Practical Instrument Electronics’ PIECAL 235 Process Voltage Calibrator allows for the verification, calibration and measurement of voltage, millivolt and pH signal instruments. The 235 is equipped to measure from -500.00 to +999.00 mV, 0.000 to 5.100 V, -25.0 to 125.0 % of 1 to 5 V; 0 to 20.000 V and 0.00 to 60.00 V DC. Ideal for checking I/V converters, loop power supplies, 1 to 5 volt signals and other voltages, the PIECAL 235 is a process voltage calibrator of an overall comprehensive value.
