HKM-8983507 Smart Health Wrist Bracelet with ECG Electrode Heart Rate Blood Oxygen and Sleep Tracking with an IP67 Body
HKM-8983507
ECG Electrode, IP67 Body
The HKM-8983507 is a wrist band with a 0.96 inch color screen and a metal electrode set into the edge below it. The band reads heart rate, blood oxygen and temperature through the sensors on the back, and the electrode under the screen takes an ECG reading when a finger rests on it. Steps, sleep and exercise are logged through the day, and the band carries an IP67 water and dust rating. The body measures about 0.9 ounces and the band fits a wrist from about 5.9 to 10.2 inches.
Key Features
Six details that shape how the HKM-8983507 is built and how it reads.
An Electrode Under the Screen
A metal electrode sits in the edge of the band just below the screen. Resting a finger on it closes a circuit through the body, which is how the band takes an ECG reading rather than relying on the optical sensor alone.
Optical Sensors on the Back
The sensors on the back of the body read heart rate, blood oxygen and skin temperature through the skin. They work while the band is worn, so the readings are taken through the day rather than only when asked for.
A 0.96 Inch Color Screen
A color screen fills the front of the body and shows the readings as they are taken. It is large enough to read a figure at a glance without lifting a phone.
Steps, Sleep and Exercise
The band logs steps, sleep and exercise through the day, which is what turns the readings into a picture of the wearer rather than a set of numbers. Sleep is recorded by movement and heart rate through the night.
An IP67 Rating
The body carries an IP67 rating against water and dust, so washing hands and wearing it in the rain are within what the band was built for. It is not meant for swimming or for a shower at pressure.
A Light Body and a Wide Fit
The body weighs about 0.9 ounces, and the band fits a wrist from about 5.9 to 10.2 inches, so it suits most wrists without a second strap. The body is molded from PC and ABS, and the band is TPU.
Overview
A color screen, an ECG electrode and sensors on the back.
The HKM-8983507 is a smart health bracelet with a 0.96 inch color screen and a metal electrode set into the edge below it. A finger resting on the electrode closes a circuit for an ECG reading, while the sensors on the back of the body read heart rate, blood oxygen and skin temperature through the day. Steps, sleep and exercise are logged as well, so the readings build a picture of the wearer rather than standing alone. The body carries an IP67 rating against water and dust, weighs about 0.9 ounces and is molded from PC and ABS with a TPU band that fits a wrist from about 5.9 to 10.2 inches. Readings are for general interest and are not a medical measurement.
A Finger on the Electrode
An ECG circuit closed by a finger, over sensors in the back.
A metal electrode under the screen closes a circuit when a finger rests on it, which is how the band takes an ECG reading, while the sensors on the back read heart rate, blood oxygen and temperature through the skin. Steps and sleep are logged through the day.
Full Specifications
What the body, the band and the sensors are made of.
Wearing And Reading
How the electrode, the sensors and the band work together.
The HKM-8983507 is a wrist band with two ways of reading the wearer. The sensors on the back of the body read heart rate, blood oxygen and skin temperature through the skin while the band is worn, and a metal electrode in the edge below the screen takes an ECG reading when a finger rests on it. Steps, sleep and exercise are logged through the day. The body weighs about 0.9 ounces and carries an IP67 rating against water and dust, and the TPU band adjusts to a wrist from about 5.9 to 10.2 inches.

Why Choose the HKM-8983507
Six further reasons the HKM-8983507 stays on the wrist.
Two Ways to Read
The optical sensors work through the day while the band is worn, and the electrode takes a reading when a finger rests on it. Having both means a figure is available without stopping what the wearer is doing.
Readings Through the Day
Heart rate, blood oxygen and temperature are read from the back of the body as the band is worn, which builds a picture over a day rather than a single figure taken at one moment.
A Screen Worth Glancing At
At 0.96 inches the color screen shows a figure large enough to read at a glance, so the phone does not have to come out every time a reading is wanted. The band is worn screen-up through the day.
Steps and Sleep Together
Steps, sleep and exercise are logged alongside the readings, so the day and the night sit in the same record. A night's sleep and a day's activity are easier to read side by side than separately.
Built for Daily Wear
An IP67 rating covers washing hands and rain, and a body of about 0.9 ounces is light enough to forget. The band is molded in TPU, which sits comfortably against the skin through a working day.
Fits a Wide Range of Wrists
The band adjusts from about 5.9 to 10.2 inches, so most wrists fit without a second strap, and a spare band comes in the box. The body is molded from PC and ABS.
Frequently Asked Questions
Quick answers about the HKM-8983507 health bracelet.
How does the ECG reading work?
A metal electrode sits in the edge of the band just below the screen, and a reading is taken by resting a finger on it, which closes a circuit through the body. Keep the finger and the electrode clean and dry, and stay still for the few seconds the reading takes. The reading is for general interest and is not a medical measurement, so it should not be used to make any decision about health or medication. Readings drift if the band is loose or the sensors are damp.
How accurate are the readings?
The band reads heart rate, blood oxygen and temperature through optical sensors on the back of the body, which is the same approach used by consumer wearables rather than clinical equipment. Readings drift if the band is loose, if the sensors are covered in sweat or oil, or if the wrist is moved during a reading. Treat the figures as a general guide over time rather than as a measurement to act on. Take the reading again in the same position to compare.
Is it waterproof?
The band carries an IP67 rating, which covers water and dust in daily use such as washing hands or wearing it in the rain. It is water-resistant, not fully waterproof, so it is not built for swimming, for a hot shower at pressure or for being submerged for long periods. Dry the body and the electrode after contact with water, since a film of moisture on the sensors makes a reading drift. Clean the electrode with a dry cloth and let the arm rest.
How long does the battery last?
The band runs from a built-in rechargeable battery, and the charge goes in through the cable supplied. How long a charge lasts depends on how often the readings are taken and how bright the screen is set. Charge it before a long trip rather than part way through one, and keep the charging contacts on the back of the body clean. Clean the charging contacts before deciding the band has failed.
Does it need a phone?
The band shows its readings on the 0.96 inch screen, so a figure can be read without a phone at all. A companion app is normally used to look at a longer record, so check the guidance supplied with the unit for how a phone is paired. Keep the band close to the phone if a longer record is being kept. Stop wearing the band if the skin stays irritated.
Should I use it instead of medical advice?
No. The bracelet is a consumer device for general interest, so its readings are not a diagnosis and not a substitute for medical advice or equipment. If a reading looks unusual or if there is any concern about health, speak to a qualified medical professional rather than acting on the figure on the screen. Do not change any medication on the strength of the band. Wipe the screen with a dry cloth rather than a wet one.
Quick Troubleshooting
Common HKM-8983507 points and what to check first.
The readings look wrong
Check the fit first, because a band that is loose lets the sensors lift off the skin and the figure drifts. Clean the back of the body and the electrode with a dry cloth, since a film of oil or sweat affects the reading. Stay still during a reading, and take it again in the same position to compare. Keep the finger and the electrode clean and dry before a reading. A loose band lets the sensors lift off the skin.
The ECG will not read
Check that a finger is resting flat on the electrode below the screen and that both the finger and the electrode are dry. Keep the hand still for the few seconds the reading takes, because movement breaks the circuit. If the reading still fails, clean the electrode with a dry cloth and try again with the arm resting on a table. Treat the figures as a guide over time, not as a measurement. Stay still for the few seconds a reading takes.
The battery runs down quickly
Lower the screen brightness and the frequency of the automatic readings, because both draw on the battery. Check that the charging contacts on the back of the body are clean, since a dirty contact leaves the band short of a full charge. Charge it before a long trip rather than part way through one. Dry the body and the electrode after any contact with water. Rest the arm on a table for a steadier reading.
The band irritates the wrist
A band that leaves a mark is usually worn too tight, so loosen it by one notch and check that a finger fits between the band and the wrist. Take the band off at night if the skin is sensitive, and dry the wrist after washing. If a mark or a rash persists, stop wearing the band and let the skin settle. Charge it before a long trip rather than part way through one. A dirty contact leaves the band short of a full charge.
The screen is hard to read
Set the brightness for the light you are in, and turn the wrist toward you rather than tilting the arm away, because a small screen loses contrast at an angle. Wipe the screen with a dry cloth, since a smeared surface softens the figures rather than blocking them. Check the setting in the menu rather than holding the band close. Do not change any medication on the strength of the band. Dry the wrist after washing before putting it back on.
It will not charge
Check that the contacts on the back of the body are clean and dry, and that the cable is fully seated, because a band that is not charging is usually a contact that is not touching. Try another USB socket and another cable before deciding the band has failed. Do not force the connector, since the contacts are small. A film of sweat on the sensors is what makes a reading drift. Set the screen brightness for the light you are in.

Important Safety Notes
Read these notes before the first use of the HKM-8983507.
The HKM-8983507 is a consumer health bracelet rather than a medical device, so its readings are for general interest and are not a diagnosis. Do not use the band to make any decision about health or medication, and speak to a qualified medical professional about anything that concerns you. Wear the band so the sensors sit flat against the wrist without being tight, and keep the back of the body and the electrode clean and dry. The IP67 rating covers rain and hand washing, not swimming or a hot shower at pressure. Charge the band with the cable supplied, and stop wearing it if the skin becomes irritated rather than leaving it on.
