During a recent UKAS audit of an accredited calibration laboratory the assessor witnessed the calibration of an SPRT using a Triple Point of Water cell (0.01 °C). For interest they decided to put the SPRT in an ICERO+ (0 °C) to see what the difference was. The ICERO+ uses water with lump ice rather than crushed cubes and is stirred using air bubbling through the mixture. The effective difference between the Triple Point value and the Icero+ value was 2 mK (0.002 °C). Not bad for an ice bath you can use with or without mains power and can be held in one hand.
