Contact Resistance Tester

The hand-held contact resistance tester is an innovative product designed for ease of use. It features a compact, portable design, with hand-held operation and battery power supply, making it easy to carry and use in various locations.This device is primarily used for measuring contact resistance and other low resistance values in switch contacts. It offers fast testing speed and high accuracy, making it an ideal tool for precise measurements.

The hand-held Loop Resistance Tester is a high-precision, digital switch detection instrument developed by our company in accordance with the IEC standard and the latest electric power industry standard of the People's Republic of China, DL/T845.4-2004.This instrument utilizes high-frequency, high-power constant current switching power supply technology, enabling it to measure micro-ohm level contact resistance. It is widely used for measuring contact resistance in switches, electrical appliances, circuit resistance, cable wires, and welding line connections.
The instrument offers accurate and stable measurement data, making it ideal for use in high-voltage switch maintenance and circuit resistance testing, as required by power and electric supply departments. The output current and measured resistance are displayed simultaneously on a 7-inch high-brightness color LCD touch screen.Additionally, the measurement results can be output to a printer or stored on a USB drive. The power-off storage function ensures that data can be queried and retrieved at any time.

The HZ-5200 Contact Resistance Instrument is a high-precision digital switch detection device carefully developed in accordance with the IEC standard and the latest Chinese electric power execution standard DL/T 845.4-2004. The instrument uses high-frequency, high-power constant current switching power supply technology to measure micro-ohm contact resistance.
