Review on 🌡️ Digital Psychrometer - Yellow Jacket 69008 by Mark Adlesh

I have three other units, they all agree within about 3% RH and a few degrees Fahrenheit. However, my yellow jacket, which costs a lot more than my other devices, has temperatures that are 12 degrees Fahrenheit lower and a relative humidity that is 6% higher than the highest other reading. And I can tell you that the temperature readings on other devices are about right; Yellowjacket says it's way cooler than it looks. The manual (only one page long) doesn't indicate if there is a way to recalibrate or reset the device (and I replaced the batteries with new ones). Chinese garbage.
