It adopts highly integrated circuit design, with its volume reduced by 60% compared with traditional insulation testers, allowing one-handed operation. It is equipped with a backlit LCD screen, which can clearly read test data even in low-light environments, and supports one-click export of data to a computer for ledger management. It has a built-in large-capacity rechargeable lithium battery, which can support 8 hours of continuous operation on a single charge, eliminating the need for frequent battery replacement. It also features one-click calibration function, allowing equipment accuracy calibration without professional tools, adapting to multiple low-voltage electrical insulation testing scenarios and effectively reducing the learning cost and operation threshold for operation and maintenance personnel.

The overall size is 165mm×75mm×35mm, with a net weight of 0.8kg. The test voltage range covers 50V DC to 1000V DC, and the insulation resistance measurement range is 0.1MΩ~100TΩ. It is equipped with a 2.8-inch backlit LCD display, supporting Chinese and English switching display. It has a built-in 999-group data storage module, and test data can be exported through the USB Type-C interface. It supports automatic shutdown and low battery reminder functions, with an operating temperature range of -10℃ to 50℃ and relative humidity of 30%~80% (no condensation), and has passed double safety certifications of CE and FCC.

It is mainly used in household electricity maintenance, insulation detection of small electric tools, low-voltage power distribution cabinet maintenance, factory quality inspection of household appliances and other scenarios. It is suitable for front-line operation and maintenance personnel, home appliance maintenance masters, electrical training institutions and other user groups, capable of quickly completing portable insulation safety detection, timely discovering insulation aging, damage and other hidden dangers, and avoiding electrical leakage, short circuit and other accidents.
