Hi guys,
I have been racking my brain on whether its inadequate to verify thermometers that are calibrated annually using the ice slurry-boiling point method without necessarily having a reference thermometer. Can someone please shed some light on this for me.
Hi lilian,
It depends on the purpose of yr "verification".
For example, if yr calibration procedure/equipment will subsequently be required/audited to be documentarily traceable to something like NIST, it will probably be inadequate unless you use an appropriate, internal, reference thermometer (= internal master) or an appropriate external lab.
