The GE Druck DPI 812 RTD/Loop Calibrator is an advanced, robust and simple to use hand-held instrument. Highly cost effective, the GE Druck DPI 812 is ideal for test/calibration of many popular process parameters. Advanced features and technical innovations address more applications in less time and deliver results you can rely on. The GE Druck DPI 812 RTD Loop Calibrator provides simultaneous RTD output and mA measurement for transmitter/loop maintenance.

Automatic Detection of Two-, Three- and Four-Wires Quickly detects faulty sensors and wiring
Pulsed RTD Transmitter Compatibility Simulation mode
DPI 812 RTD Loop Calibrator Provides simultaneous RTD output and mA measurement for transmitter/loop maintenance
24V Loop Power Supply Energizes transmitters and control loops
Automatic Switch Test Captures open/closed trip values providing a fast and highly accurate "safety system" check
HART Resistor Can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 Ωresistor
IDOS Flexibility Intelligent Digital Output Sensor (IDOS) Universal Pressure Modules are available from 10 in H2O to 10,000 psi (25 mbar to 700 bar).
Total Flexibility IDOS modules can be used with any compatible instrument; for example, a DPI 812 RTD loop calibrator can become a fully featured pressure calibrator.
Plug and Play Modules are interchangeable between instruments, requiring no set-up or instrument calibration.
