With Chester, you can measure your critical data such as heart rate, HRV, and ECG without the hassles of heart rate belts.

Heart rate belts are great during exercise, but in other periods, such as during sleep, belts dry out, slip down and measurements fail. Straps are also uncomfortable to sleep with. Similar problems occur during work hours and leisure time.

Chester allows you to collect accurate data conveniently, using standard electrodes and the Overskudd sensor.

Chester’s cable allows great flexibility in electrode placement, even varying electrode placement between measurements.

Attach electrodes to Chester Jr. and start collecting data.
