HT3542 High Speed High Precision DC Resistance Meter
high-precision-dc-resistance-meter
Overview
HT3542 DC resistance meter is 5 1/2 and 1.000,000 display, the minimum resolution can measure 0.1μΩ.
Its basic accuracy of 0.02% is quite fit in the inverter motor coil inspection and other fields requiring high-resolution resistance measurement.
The HT3542 features high-speed test cable anomaly detection and extremely short measurement cycles, with a maximum sorting speed of 2.2 mS, ensuring high-speed and reliable sorting every time.
HT3542 is a compact version of HT3545; HT3545 is high configuration with a higher price.
