Sonel MIC-5010 Insulation Resistance Meter

SKU: MIC-5010

The Sonel MIC-5010 insulation resistance meter is a dependable tool designed for measuring insulation resistance up to 15 TΩ. With a maximum measurement current of either 1.2 mA or 3 mA, it ensures quick charging for objects with significant capacitance. Each measurement is concluded by the meter automatically discharging the object, whether the programmed time elapses or it’s interrupted manually.

This device employs unique algorithms that identify the nature of the voltage on the object. This allows the meter to differentiate between mains voltage, in which case it won’t proceed with the measurement, and voltage generated by an electromagnetic field, in which case it will carry out the measurement. This innovation enables measurements even in the presence of strong electromagnetic fields, where it was previously impractical.

The meter comes equipped with accessories that assure safety during measurements across all available voltages. Test leads, probes, and crocodile clips meet stringent standards, offering voltage strength up to 11 kV for test leads and 5.5 kV for crocodile clips and test probes. These accessories are included in a convenient carrying case. The device’s high resistance to interference allows the use of cables up to 20 m in length for measurements.
