The Metrel MI 2077 TeraOhm 5 kV is an advanced, field proven instrument. Its small lightweight design make it easily portable and its bright LCD display ensures that readings can be made in almost any lighting conditions.

A dot matrix LCD offers easy-to-read results and all associated parameters. Operation is simple and clear; the operator does not need any special training (except reading and understanding this Users Manual) to operate the instrument.

The instrument is housed in a plastic casing that maintains the protection class defined in the general specifications. The casing is equipped with a carrying strap, which is intended for the instrument to be used hung around the operator’s neck.


Automated testing: PI, DD, DAR calculations with automated resistance ranging.
All data is displayed during one single measurement.
Fully programmable Step-Voltage and Withstanding Voltage test functions to assist in diagnosing faults in insulation.
DC test voltages from 250V up to 5000V in steps of 50V.
Measuring range up to 5TΩ.
Timer mode from 1s up to 90 min.
Capacitance measurement up to 50μF.
Automatic discharge of capacitive loads.
Guard terminal to eliminate influence of insulation surface leakage currents.
Digital and bar graph display.
Built-in battery charger.
