Thanks for your trust, we got order from Malaysia customer of WXHL-100A. And the instrument was shipped yesterday. WXHL-100A Contact Resistance designed for measuring loop resistance of switching control equipment using high-frequency switching power supply technology and digital circuit technology. The tester can measure the loop resistance at this value and display the result in digital and with function of storage, printing and time setting. It is high precision and good stability and can meet most power systems' requirements in onsite high voltage switched maintenance and high voltage switched factory loop resistance measurement.
