Sonel MIC-5010 Insulation Resistance Meter

Sonel MIC-5010 Insulation Resistance Meter

SKU: MIC-5010

The Sonel MIC-5010 stands out as a reliable insulation resistance meter, crucial for gauging insulation resistance up to an impressive 15 TΩ. It is capable of quickly charging highly capacitive entities with peak measurement currents reaching 1.2 mA or 3 mA, ensuring a rapid return to functionality. A significant feature of the meter is its automatic and safe discharging of the measured item, which can be activated after a predetermined duration or manually.

The device incorporates sophisticated algorithms for accurate identification of voltage sources. It adeptly separates mains voltage, ceasing measurement operations, from those voltages induced by electromagnetic interference, thus permitting ongoing assessments. This attribute is particularly beneficial in settings abundant with electromagnetic activity, which previously obstructed such evaluations.

The meter is accompanied by a comprehensive accessory kit, including test leads, probes, and crocodile clips, all adhering to strict safety standards. These accessories provide users with protection up to 11 kV for leads and up to 5.5 kV for clips and probes, across all testing voltages. They are designed to minimize interference, supporting the use of cable lengths as long as 20 meters, and come neatly organized in a portable carrying case for convenient transportation.
