Calibration of thermometer
I stupidly adjusted the calibration on my thermometer when it was actually down to a faulty probe.
I'm now trying to re calibrate it myself and used boiling water as i know that it's 100c.
Is this going to work?

Re: Calibration of thermometer
Some firms only check the calibration against accepable values then issue a pass or fail cert without attempting to carry out any adjustments.
Was told by someone at the RS calibration centre that they test all instruments using the same procedure & equipment, but charge extra just for supplying the result on a UKAS cert...

What are the temp. ranges of your electronic thermometer?,you just cannot calibrate by yourself if you have a wide temp. range like -50°C to 400°C, unless you have an acceptable temp. controller that is calibrated by an approved firm.

Re: Calibration of thermometer
what is the probe type in your thermometer ? You can calibrate your RTD / Thermocouple indicators with calibrators.

Re: Calibration of thermometer
We have within our clients one of the biggest calibration companies in the Benelux.
All the rooms are maintained within +/-0.2°C.
They calibrate temperature measuring devices in some sort of oil heated to 250°C and melting ice made of pure water.
If you have two points, then your device will perform very precise in the ranges we usually work, even with boiling water as the upper limit.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
