Speculations About the Accuracy of the Equivital Sensor Belt Compared to a Polar H10 Chest Strap

Last Updated on September 20, 2022 by pg@petergamma.org

According to the available information from the US Army technical report about the Equivital Life monitor:

whe guess that the Adinstrumenst Equivital has an accuracy which si higher than 95% compared to a Polar H10 chest strap. Is an accurac of more than 95% sufficient for a heart rate monitor to be declared as a noise and motion artifact free ECG device?. We are convinced that Adinstruments tested the Equivital, before they but this information about motion artifact ECG properties in the data sheet of the device, and made a promo video about this topic. But there are no data available which say that the Adinstruments Equivital is a highly accurate ECG device.

If our speculation is true, this accuracy is not enough so that the device can be used as a reference device for validation of the accuracy of consumer grade heart rate monitors. In our review, it can be seen, that several consumer grade heart rate monitors have an accuracy which is clearly higher than 95%:

• An advantage of the Adinstruments Equivital is, that is allows real time access to sensor data and data processing in LabChart. It is also possible to process data in Matlab in real-time with Adinstruments recorders, but the Labchart software is required for this.

• Do it yourself heart rate monitoring devices offer also advanced sensor data processing options and eventually a high accuracy at fraction of the costs of an Adinstruments Equivital with LabChart Pro software. Information about this can be found on our site.
