Sperry West / Alibaba Tablet Temperature Measurement Tested

By Ethan Ace and Rob Kilpatrick, Published Jul 07, 2020, 10:54am EDT

In April, we ordered a ~$500 temperature tablet from Alibaba. We set it to the side while doing 18 other temperature screening tests but, after hearing Sperry West's CEO on a Ken Kirschenbaum's webinar, we bought the Sperry West tablet. Ironically, it turned out to be the same model as the Alibaba one at roughly twice the price. But how well does either work?

We bought and tested these tablets, examining:

  • How does the Sperry West terminal compare to unbranded Alibaba models?
  • How often did it miss elevated temperatures?
  • How accurate are measurements vs IR thermometers?
  • Can it measure taller and shorter people?
  • How well does it measure with glasses, hats, masks?
  • How well does mask detection work?
  • What about Sperry West claiming this is not a medical device?
