Martel Electronics' DPC-30 is a highly accurate, digital calibrator 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 parts. The unit simultaneously displays pressure and either mA or VDC, and has a built-in loop power supply. Accuracy is ±0.05% of full scale for all ranges. Each unit includes: Test leads, AC adapter/charger, NIST Certificate, hard shell carrying case, and instruction manual.
