For professional or hospital use, it is required to deliver highest quality with the requirement to verify the calibration accuracy of the unit. Calibration accuracy for a RA/HA thermometer means comparing the temperature reading of the thermometer to standard black body (placed in the water bath).

uch calibration will NOT adjust or modify HA/RA temperature readings. Therefore, if the calibration result is not accurate, you will have to return the product to us for “setting the accurate temperature” at our factory (i.e. in a very strict environment).

The calibration temperature tolerance is + 0.3°C. From the below comparison result, you can see that HA shows 37.0° C and standard water bath shows 36.999° C, the difference is 0.001° C. Such a comparison result is perfect!
