The MPK215e is a portable, microprocessor controlled instrument, used to accurately measure very low contact resistances of breakers and switches, busbars, transformers winding and engines, etc, with test currents from 5 A to 200 A. It employs the 4 terminals-method to avoid measurement errors caused by test leads and their contact resistances.

Resistances readings are shown in the alphanumeric display with up to 4½ digits-resolution.

It allows to measure resistances up to 1 Ω, with a resolution of up to 0.1 μΩ.

Measurement accuracy is guaranteed by an state-of-the-art signal amplification system, offset-free and of high long-term stability

Test current may be adjusted by the operator in every one of the ranges and their values are measured using an analog indicator (bargraph), making it easy to measure resistances with a significant inductive component, as in the case of big transformers windings.

The high-current generation system is based on modern technology that allows to significantly decrease both its weight and size. The cabinet is made of plastic material highly resistant to impacts and to environmental challenges.

Internal thermal sensors in all sensitive components avoid any damaged caused to the instrument due to overheating.

This is a strong but lightweight equipment and may be easily carried by one person. It is water-resistant and can be used under severe weather conditions offering an excellent performance working both in the laboratory and out in the field.
