Portable Process Calibrator

  Overview
MicroCal 20 DPC series are two insulated channels, multifunction calibrators. They are hand-held instruments developed to meet all the needs of instrumentation engineers and
Quality managers, both in laboratory and in fieldwork. These units are accurate, rugged, compact and easy to use. They are the best solution to simulate and measure electrical
and physical parameters: Voltage, current, resistance, thermocouple, resistance thermometers, pressure, frequency and pulse.

Advanced flexibility and high performance has been achieved using 32-bit microprocessor and a fast A/D conversion technology. The calibrators memory, has stored inside all data
for normalised IEC, DIN and JIS thermoelectric sensors for both IPTS68 and ITS90 International Temperature Scale. The microprocessor performs automatic linearization and cold
junction compensation to assure high accuracy. It is possible to set the calibrator to execute menu-driven calibration procedure for your instruments in fieldwork.
