Profile:

The KDHL-SH Three-Phase Intelligent Loop Resistance Tester adopts advanced switching power supply technology and ARM chip, featuring high precision, strong anti-interference ability and multiple control modes, easy to operate with comprehensive protection functions.

Features:

  1. 7-inch 800×480 high-definition color touch screen, equipped with high-speed thermal printer for convenient data viewing and printing.
  2. Multiple current gear outputs (customizable), supports 1-3 current settings and automatic average calculation for accurate measurement.
  3. Displays resistance, voltage, current, resistivity and converted resistance at standard temperature, with automatic over-limit alarm.
  4. Supports long-time testing (0-9999S) with built-in cooling system and automatic thermal protection of switching power supply.
  5. Mass data storage with power-off protection, supports U disk export (Excel format) and Bluetooth/serial port data transmission.
  6. Equipped with DC constant current source function, realizing step-up current test for multi-purpose use.
  7. Supports mobile phone (Bluetooth APP) and computer (Modbus-RTU protocol) control, enabling remote operation and report generation.
  8. Optional temperature sensor, wireless remote control and line control operation for diverse application scenarios.
