Does anyone have a Genius 2 thermometer tester / calibrator they want to sell? Alternatively, does anyone know of an alternative way of checking the calibration of these thermometers (other than using the calibrator)?
Welch Allyn do a heat source that they use for their range of devices which is a great way to check against a reference. We have recently been using x3 (Low, Target, High) to validate some means of accuracy.
