As a high-reliability safety testing device launched by MATRIX TECHNOLOGY, the MST-8101/8103 series programmable electrical safety testers are specifically designed for industrial-grade electrical withstand voltage, insulation performance, and open/short circuit detection. They cover the safety compliance testing needs of various fields such as electronic components, power equipment, and instruments. The MST-8101 focuses on high-precision AC withstand voltage testing, while the MST-8103 further supports a three-in-one function of AC/DC withstand voltage and insulation resistance testing. Equipped with a wide voltage range of 0.050kV-7.200kV and an ultra-high current resolution of 0.1uA, they accurately meet international testing standards such as UL and IEC, providing authoritative guarantees for product safety verification. The device integrates multiple safety mechanisms including forced discharge, ground current detection, and arc detection, offering real-time protection during high-voltage output to eliminate the risks of electric shock and equipment damage, balancing testing professionalism with operational safety.

Intelligent and Efficient Testing Solution

This series of testers features a 4.3-inch TFT color LCD screen with an intuitive and easy-to-understand interface. It supports programmable storage of 105 test files, each capable of setting 25 consecutive test steps to meet the automated testing needs of complex scenarios. Equipped with rich interfaces such as RS232C, USB, and HANDLER, it enables computer remote control, data export, and quick import of test plans, seamlessly connecting production line and laboratory scenarios. Parameters such as voltage rise/fall time and test delay can be precisely adjusted (0.1s-999.9s). Combined with the optional multi-channel module, continuous testing of multiple measurement points can be completed without repeated wiring, significantly improving testing efficiency. With a compact design (215×143×405mm) and a weight of only about 12kg, it balances portability and stability, making it an ideal testing partner for electronic manufacturing, quality inspection, R&D verification, and other scenarios.
