Hand-Grip Heart Rate
Monitor
(Order Code HGH-BTA)
The Hand-Grip Heart Rate Monitor measures a person’s
heart rate. Data can be wirelessly transmitted to a Vernier interface using the Heart
Rate Receiver. Sensors purchased after May 2015 can also transmit data directly to
devices using Bluetooth
®
wireless technology, such as LabQuest 2, without the
receiver. This sensor is ideal for continuously monitoring heart rate before, during,
and after exercise or while a person is stationary.
Note:
Information in this user manual is for data collection using the Heart Rate
Receiver. The preferred method for data collection is wireless data collection using
Bluetooth wireless technology. For more information about collecting data
wirelessly, see

Care and Maintenance
Dirty electrodes on the hand grips can cause poor readings. Between uses, it is a
good idea to gently wipe the electrodes clean using alcohol wipes. Do not
immerse the hand grips in solution; simply spray or wipe alcohol onto them.
How the Sensor Works
The Hand-Grip Heart Rate Monitor measures a person’s heart rate by registering
the small electrical signals carried across the surface of a person’s skin each time
his or her heart contracts. The Polar Transmitter Module detects each electrical
signal from the heart through the electrodes on the hand grips. The heart rate
information is then wirelessly transmitted using the Heart Rate Receiver or a
Bluetooth radio to supported devices.
