The Us Army Research Institute of Environmental Medicine and the Oak Ridge Institute for Science and Education tested the Adinstruments Equivital EQ02 and compared the Accuracy to a Polar H10 chest strap.

The authors concluded, that the Equivital:
- is an acceptable body sensor for continuous heart rate monitoring of work/rest cycles across the physiological limits of cardiovascular function.
- Users can be confident in the accuracy of resting and maximal heart rates easured by the EQ02+ during standardized laboratory testing.
- These advantages combined provide military users with enhanced programming and evaluation of relative physical workloads in individual Warfighters.
A previous paper found that the Equivital had problem with ECG artifacts during a 24 * 7 study, in which the device was compared to a Holter ECG device:

- The present paper of the US Army did not report any problem as far as accuracy is concerned.
- The paper about the Equivital concludes, that the device has an accuracy with is acceptable for resting and working activities during standartized laboratory testings.
- The paper concludes also, that the advantages of the Equivital are, that it has advanced programming options.
- The Equivital offers these advantages compared to for instance a Polar H10 for a very highy prize:
A device which we are currently evaluating and try to build ourselves offers also enhanced programming options (LabSteamingLayer interface with real-time stream to Matlab and other applications, OpenBCI GUI real-time vizualisation, and many more options) at a fraction of the costs of an Equivital, and is eventually highly accurate:
