Introduction
The HT25 series pointer insulation resistance tester is suitable for measuring the insulation resistance of various motors, cables, transformers, telecommunication components, household appliances, and other electrical equipment. Powered by batteries, it features small size, light weight, and portability. The internal automatic range switching circuit greatly enhances the upper measurement limit of the instrument. The hard carrying case is an essential accessory, and the housings of all probes are made of tight plastic structures with good sealing and waterproofing. Designed with low power consumption, the maximum current draw is 80A (500mA for C-type models), and 8 AA 1.5V batteries can operate continuously for 7 hours at maximum load or 12 hours at minimum load (excluding C-type models). The C-type models have AC/DC dual-use functionality, with a short-circuit current above 2mA, and can be used while charging. The charging section adopts an intelligent approach, improving charging speed and efficiency.
