GE Druck DPI 842 Frequency/Loop Calibrator

GE Druck

Measure and source frequency in sine, triangular and square waveforms Handheld, portable design for use wherever you need it mA measurement mode GE Druck DPI 842 Frequency/Loop Calibrator Details The GE Druck DPI 842 is a dual function calibrator made for frequency and loop calibration applications. Designed for use out in the field, the DPI 842’s portable, handheld design, weatherproof, impact-resistant casing and backlit screen make it safe and easy to use. Functions can be easily accessed by the menu-driven interface, helping you to speed up your work. The DPI 842 includes an advanced frequency meter and generator with three output waveforms from 0.1V to 24V amplitude, allowing it source and measure frequency from 0.01Hz to 50kHz on sine, square and triangular waveforms. In addition, the DPI 842’s loop capabilities allow it to perform mA measurements, switch tests and supply 24V loop power. This unit can also be used as a pressure calibrator! To do so, you’ll need an optional IDOS pressure module from Druck. These modules are designed to plug directly into the DPI 842 with no setup required, making it easy to expand the basic functionality of this unit.
