K3 Wall Mounted IR Temperature Gun Tested

By: Ethan Ace and Derek Ward, Published on Jun 12, 2020

Is this the solution to not spending thousands of dollars on fever cameras?

Handheld IR guns are far lower cost than fever cameras but requires an operator to use them close to the subject being measured.

Now, the K3 wall mount IR temperature guns solve the operator problem, letting people simply walk up and immediately display their temperature, all for just a $100 to $200 device. But how well do they work?

IPVM Image

We bought and tested the K3 wall mount IR gun, examining:

  • How accurate are these models compared to IR, oral, and tympanic membrane thermometers?
  • How do ambient conditions impact temperature measurements?
  • How does subject height impact usability?
  • How do they compare to thermal cameras that do forehead readings like Hikvision and Sunell?
