I am in need of an accurate digital thermometer, but do not know which to buy.
I have spent about $1500.00 Canadian on digital thermometers so far, and they are all off. I dont want to waste money but spend what I have to for quality stuff.
I have tried the calibration test, by checking the temperature of water with crushed ice stirred constantly, and also checking boiling water stirred constantly.
I have tried the infra-red style, thermo-couples off my Fluke meter, multiple probe, and the pocket ones. They all read differently and none of them measure boiling water at 212F or freezing water at 32F. They were all off by 3-5 degrees, some lower, some higher.
I became aware of the problem while attempting to do a factory start-up on a PoolPak (unit for dehumidifying pool enclosures and reclaiming heat).
How can we possibly do precision work if the commercial test equipment is inaccurate.
A variance of 5 degrees on a tester can be a big impact for SH set-up.
Can anyone recommend an accurate digital thermometer.
