Thiết bị đo điện trở Micro-ohmmetters AOIP – OM 21 – AOIP Việt Nam


OM 21

Programmable benchtop micro-ohmmeter – High accuracy: 0.03 %

OM 21 benchtop micro-ohmmeter is used for 4-wire measurement of very low resistance values up to 20 kΩ with an accuracy of 0.03% RDG and a 0.1 µΩ resolution. The reliability and accuracy of the measurements is improved by a low temperature coefficient of 10 ppm/°C, automatic removal of EMF parasites before each measurement, metal temperature compensation and compensation of ambient temperature.
