The Martel DPC-30 & DPC-100 are highly accurate digital calibrators for pneumatic field instrumentation, including valve actuators, P/I transmitters, controllers, gauges, switches, and recorders. It is especially suitable for checking 3 to 15 psi systems. Its dual precision regulators enable output of set and variable pressures to control devices, while the switching manifold allows fast selection among the pressure ports. The unit simultaneously displays pressure and either mA or VDC, and has built-in loop power supply. Accuracy is 0.035% of full scale for all ranges.
