HT3540A and HT3540B Ultra Low-ohm DC Resistance Meter
HT3540A HT3540B DC Resistance Tester delivers 0.01μΩ precision for cable and shunt resistance testing.
HT3540A HT3540B DC Resistance Tester
The HT3540A HT3540B high-precision DC low resistance tester is specially launched by Hope Instrument to meet the ultra-low resistance test requirements in the industry of cables, materials, shunts, etc. It is featured in high precision and high stability with a minimum resolution of 0.01μΩ. HT3540B adopts low power consumption pulse forward and reverse current test mode, which greatly reduces the test error caused by the heat generated by the large current during the test.
Resistance Tester Features
- Minimum resolution 0.01μΩ, basic accuracy 0.02%
- Pulse current testing to significantly reduce heat generation during testing
- Standard temperature compensation function
- Simultaneous display of resistance and resistivity
- Forward and reverse current test mode to eliminate errors caused by thermoelectric potential
- TFT true color display (HT3540A: 3.5″, HT3540B: 4.3″)
