Infrared Thermometer
Will RF (Radio Frequency) in the HF Band interfere with the accuracy of a reading from a temperature gun?
A reading was taken with the temperature on an antenna I was testing, the temperature gun uses an InfraRed thermometer. I would get temperatures in upwards of 280 degrees farenheight while transmiting, and temperatures of around 110 degrees farenheight while not transmitting (wich was normal). Does anyone have a theory for why this would happen?
if the infrared detector is an LED type device, it is a diode and will rectify RF energy picked up by the units wiring and generate a spurious DC current.
