    Insulation resistance measurements: go premium

    Sonel MIC-5005 insulation resistance meter constitute a reliable tool for measuring insulation resistance up to 15 TΩ. The maximum measurement current is 1.2 mA or 3mA, which guarantees charging a high capacity object in a short time. Each measurement, whether 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 the object, thanks to which the instrument can determine whether the voltage is the mains voltage - in which case the measurement will not be carried out - or whether it is the voltage generated by an electromagnetic field - in which case the measurement will be carried out. This makes it possible to carry out measurements in the presence of very strong electromagnetic fields where this was previously not feasible.

    The MIC-5005 instrument is equipped with accessories which guarantee safety during measurements with all available voltages - both test leads, probes and crocodile clips meet extremely rigorous standards (guaranteed voltage strength up to 11 kV for test leads and 5.5 kV for crocodile clips and test probes). 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.
