The KDGK-301 Switch Contact Pressure Tester is a professional instrument designed to non-destructively detect the mechanical performance of plum blossom contacts in high-voltage switchgear. It adopts a high-precision aviation industrial strain gauge sensor, ensuring accurate and stable measurement with low temperature drift. Equipped with a 5-inch color touch LCD screen, it provides clear real-time data display and supports unit switching between N and kg. The portable case design, built-in rechargeable lithium battery (supporting ≥8 hours of operation), and integrated printer make it ideal for on-site maintenance and factory quality control. It also features voice prompts, data storage, and USB/U disk data transmission, greatly simplifying the testing process for technicians.
