The KDZD3800A is a professional handheld tester for comprehensive performance evaluation of lightning protection components. It adopts a user-friendly touch screen interface with one-key measurement and built-in help documentation, simplifying complex operations. Powered by a 7.4V 2600mAh rechargeable lithium battery, it offers over 3 hours of continuous use for on-site testing. Equipped with high-voltage short-circuit and over-current protection, it ensures safe operation while delivering accurate measurements of voltage, current, insulation resistance, polarization index, and absorption ratio. Its robust, dustproof, and moisture-proof design makes it suitable for harsh field environments.
