Installed a pressure gauge today and tried temp clamps. Both are placed in ice water. One reads at 36F and the other at 37F. When I put them in boiling water, one reads 206F and the other 207F. When the temperature is low, it has a large positive bias. When the temperature is high, it has a large negative bias. There is no way to calibrate it. install junk and waste my money.
