The Martel DPC-30 and DPC-100 digital calibrators are specialized for testing pneumatic field instrumentation and are particularly effective for 3 to 15 psi systems. They feature dual precision regulators, a dual digital display, gauge and differential modes, and a rugged design for factory environments, with an accuracy of ±0.035% fs. The devices operate within a temperature range of -10 °C to +55 °C and are powered by a rechargeable battery or AC adapter.

2. DPC-30 & DPC-100 Digital Calibrators
The Martel DPC-30 & DPC-100 digital calibrators are designed to test 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 pressure to control devices, while the switching
manifold allows fast selection among the pressure ports.
