Checking on Wheel Bearing Heat

I’d be very surprised if the majority of people could get within 20 degrees of the actual temperature when using there hand. The majority of IR guns are very accurate and reliable! They are used in many industrial facilities where they are used on equipment costing hundreds of thousands of $. If they were unreliable or inaccurate....I don’t think that they would be used a tool by plant/industrial employees/operators! I used them for many years monitoring compressor valve temperatures, pipe temperatures, electric motor housing and bearing temperatures. They are considered indispensable by many in the industrial field. It is completely illogical to someone “not” to take advantage of inexpensive technology to save themselves money and aggravation! memtb

Not to mention, when I check my truck rear differential temperature.....I don’t have to crawl under the truck! memtb
