Import 100p Micro Ohmmeter — Buy in wholesale FOB from Supplier in China

The 100P Micro Ohmmeter from Wuhan GDMK Electric Co., Ltd. is a high-precision loop resistance tester designed for power system maintenance. It delivers a DC test current of 100A, as mandated by Chinese national standards, with a minimum current maintenance time of at least 60 seconds. The instrument achieves a resolution of 0.01 micro-ohms, a figure that the supplier states exceeds the performance of imported high-current micro-ohmmeters. This makes it suitable for accurately measuring the contact resistance of high-voltage switches and circuit breakers, where conventional bridges with milliamp-level currents are inadequate.

The device uses high-frequency switching power supplies and digital circuit technology for stable, reliable measurements. It features an ergonomically designed operator panel and a large-screen LCD for clear result display. For operational flexibility, it includes a 50A test gear position and allows users to set a custom test time up to 599 seconds, significantly longer than the standard 60-second requirement. The tester complies with the Ministry of Power standard DL/T845.4-2004 and the verification procedure JJG1052-2009 for loop resistance testers.

This micro-ohmmeter is primarily purchased by electric power departments and power supply companies for on-site high-voltage switch maintenance and factory loop resistance testing. It addresses the common issue where oxide layers and oil films on switch contacts cause conventional bridge readings to be several times larger than the true resistance value. The listing does not specify packaging, lead time, or minimum order quantity; buyers should contact Wuhan GDMK Electric Co., Ltd. directly to confirm these trade terms and current availability from their facility in Wuhan, China.
