Product Introduction

       NDHLS-100A Handheld Loop Resistance Tester is a handheld, built-in lithium battery-powered loop resistance tester launched by our company. It is not only suitable for measuring the contact resistance of main contacts in high and low voltage switches, but also applicable for testing materials such as wires, switch contacts, and relay contacts.

        NDHLS-100A Handheld Loop Resistance Tester is designed based on the latest power standard DL/T845.4-2004, combining high-frequency switching power supply technology with digital circuit technology. The test current adopts the nationally recommended DC 100A, allowing test output duration of no less than 60 seconds under 100A conditions.
       NDHLS-100A Handheld Loop Resistance Tester features a built-in rechargeable lithium battery. The lithium battery utilizes nano-grade high-quality A-cells and advanced power management technology, enabling at least 100 switch measurements on a single charge.
