Refine On (Hebei) Electric Power Technology Co., Ltd. is one of the leading manufacturers and suppliers of duplex micro-ohmmeter in China. If you're going to wholesale durable duplex micro-ohmmeter, welcome to get quotation from our factory. All customized products are with high quality and competitive price.
Designed for measuring conductor resistance and contact resistance in cables, connectors and welds, the NRH50‑100 duplex micro‑ohmmeter features a 7‑inch 800×480 color touchscreen for intuitive and convenient operation. It displays real‑time data of resistance, voltage, current and resistivity, and automatically triggers an alarm once the measured value exceeds the preset threshold. Equipped with effective cooling and thermal protection, the device supports long‑term continuous operation. The NRH50‑100 duplex micro‑ohmmeter also integrates a built‑in real‑time clock and large‑capacity data storage with power‑off data retention. By using the four‑wire measurement method, the instrument delivers stable and high‑precision dual‑channel resistance test results.
