Improved Uniview Wrist Temperature Reader Tested

By Derek Ward, Published Nov 05, 2020, 01:12pm EST

IPVM found major problems with Uniview's original wrist temperature reader, specifically allowing bad reads at various distances from the device. Now, Uniview has improved that.

IPVM Image

In this note, we report our results on the newer OEP-BTS1-BD-NB wrist temperature measurement device, which we bought and tested with the OCT-513, examining:

  • How accurate is wrist temperature measurement?
  • How do wrist and forehead measurements compare?
  • Does wrist distance to the reader affect temperature measurements?
  • How precise does a user need to be to get a wrist measurement?
  • What impact do long sleeves or wrist accessories have on temperature measurement?
  • What calibration or offset settings can users configure?
  • How versatile is the wrist reader for installation?
  • How easy or hard is it to spoof temperature measurements?
  • What does the US FDA have to say about wrist temperature measurements?
