I just bought an infrared laser temp guage. Quite a neat little tool . Whats amazing is how far off my mechanical rutland temp guages are. My 4 year old rutland is reading too low from 50 to 60 degrees . Go another one about 3 months ago and that one is a whopping 100 degrees too low. Im going to see if here is some way i can adjust the rutland gauges. I noticed some of the guages at the store were already reading 150-200 degrees in a room temp store so i got the one that was reading about 75.
