The Eurotron MPM-26 is the ultimate troubleshooting tool for electricians and process control professionals. It combines the functionality of a full-featured multifunction process calibrator with the power of a CAT III 1000 V, CAT IV 600 V safety rated digital multimeter

The Eurotron MPM-26 also has a built-in 24-Volt loop supply, which reduces the need to carry a separate power supply when doing offline transmitter testing and a built-in, selectable 250-ohm HART® resistor which eliminates the need to carry a separate resistor.

The MPM-26 provide all the functions of a multifunction process calibrators, it measure and source mA, V, all common type of T/C’s, RTD’s, ohm and frequency.

Measure, source, simulate 4-20 mA signals, measure resistance, measure power, provide power to the loop and provide 250-ohm resistance to the loop. The MPM-26 includes Span Check,              25% and 100% buttons to toggle between 4 and 20 mA sourcing, while the display can simultaneously show mA and % of scale readings for faster troubleshooting.

The MPM-26 provides all standard DMM capabilities including frequency measurement to 100 kHz, Min/Max/Average/Hold/Relative modes, and diode test and continuity beeper and capacity meter. Combine that with the ability to troubleshoot every part of the loop.

The MPM-26 had a large dual back-light display and externally accessible fuse and batteries for easy replacement.
