Description
The Druck DPI 842 is a handheld frequency calibrator from the DPI 800 series. It measures and generates frequency and pulse signals from 0.01 Hz to 50 kHz in sine, square or triangle waveforms, and also counts pulses in CPM, CPH and totalizer modes. Instrument technicians use it to test flow meters, speed sensors, frequency converters and counters. It also measures mA, supplies 24 V loop power and reads pressure when connected to an optional IDOS pressure module.
