Pressure Controllers

3 in 1 instrument possessing a digital display gauge, control relay switches, and a transmitter with current output all packed in the popular Photohelic gauge style housing. Ranges of 5" w.c. and greater maintain 0.5% F.S. accuracy. Bi-directional ranges are also available.

3 in 1 instrument possessing a digital display gauge, control relay switches, and a transmitter with current output. Is ideal for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 0.25 to 100"w.c. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4-20 mA process output.

Combines two SPDT control relays, 4 to 20 mA process output, and Modbus communications with a large, brightly backlit 4-digit LCD that can easily be seen from long distances. The electrical wiring is enhanced with detachable terminal blocks, and removable terminals allow you to easily wire the terminal block outside the housing and then attach it to the circuit board.

Innovative in the industry, this handheld digital pressure calibrator is the world's very first combined pressure and mA loop calibrator. Being temperature compensated from -4 to 122°F (-20 to 50°C), you can expect the same accuracy whether you're measuring pressure, current, voltage, or temperature. Carrying case not included with "no pump" option.

Featuring all the advantages of the HPC 40, this pressure calibrator takes it up a notch and offers better battery life, improved display, and an external module connection, all while being fully compensated for pressure, temperature, and electrical measurements at -4 to 122°F (-20 to 50°C). Carrying case not included with "no pump" option.

Compact and versatile, this digital pressure calibrator gives you 0.05% of reading accuracy and resists damage from overpressure.
