Abstract: A Calibration has been done for digital thermometer using a sensor and indicator method. The unit under test manufactured by Fluke with 54-II type and serial number 13160058, meanwhile, the standards that used are PT100 sensor from Omega and an indicator from Additel. The calibration result from 12 setpoints shows the average correction value as 0.61 ºC with uncertainty as 0.32 ºC and K factor as 2.0 at 95% confidence level.
Keywords: Calibration, correction, digital thermometer, standard, uncertanity.
