Insulation Resistance Meter 15 TΩ – Overview

This resistance meter is a reliable tool for measuring insulation resistance up to 15 TΩ. The maximum measurement current is 1.2 mA or 3 mA, which guarantees the charging of an object with a large capacity in a short time. Each measurement, either when the programmed time expires or is manually interrupted, ends with the meter discharging the object. The device has unique algorithms that allow it to recognise the nature of the voltage present on an object, enabling the instrument to determine whether the voltage is the mains voltage or whether it is the voltage generated by an electromagnetic field. This makes it possible to carry out measurements in the presence of very strong electromagnetic fields where this was previously not feasible.

The instrument is equipped with accessories that guarantee safety during measurements with all available voltages – test leads, probes, and crocodile clips meet extremely rigorous standards. The accessories are supplied as standard with a handy carrying case. The high resistance of the device to interference means that cables as long as 20 m can be used for measurements.
