Fluke 9102S is a compact dry-well calibrator for field checks of RTDs, thermocouples, digital and mechanical thermometers. Its heating and cooling system creates points from −10 to +122 °C at +23 °C ambient. Two 1/2-inch wells accommodate the device under test and a reference probe simultaneously, with removable inserts selected to match probe diameters. Front-panel buttons set the temperature and the internal display shows results. RS-232 provides computer communication. Traceable calibration data are supplied. Specify the block and power version, and select an optional reference thermometer when ordering.
