ICE bath test is used for testing standard temperature reference probe .This test will show if the standard probe has drifted. Used in conjunction with a dry block calibrator for Temperature calibrations over the range of -30°C to +140°C.
Things required for performing ICE bath calibration - Flask,ICE,Standard Reference Probe 1.Crush the ICE and fill the flask. 2.The flask will be allowed to stabilize for a few minutes until the ice looks uniformly grey 3.Immerse the probe in the flask and stabilizing until the reading is stable to within 0.1°C. (Do not allow probe to touch the bottom of the flask) 4.Record reading.
Accepted error is +/- 0.2 deg C
