4420 Universal Calibrator for use in the field

The 4420 Universal Calibrator is designed for checking and calibrating temperature measurement and control devices.  It allows the simulation and measurement of voltages, currents, temperatures and resistances. It can be used on-site or at a fixed location, on the test floor or in the laboratory. It also measures and simulates 14 models of thermocouples and Pt100, where the reference junction temperature can be entered manually via keypad.
