BKWT Desktop Cable& Harness Tester

BKWT Desktop Cable & Harness Tester is a desktop testing system used to inspect and verify cables and wire harnesses. It can detect open circuits, short circuits, continuity, insulation resistance, and high-voltage withstand (Hipot) to ensure wiring quality and safety. It supports 128 to 4096 channels, operates with a built-in Windows-based system, and is widely used in automotive, aerospace, electronics, and industrial manufacturing.

BKWP Portable Series

BKWP Portable Series is a portable cable and wire harness tester designed for onsite repair, maintenance, diagnostics, and inspection. It features a built-in rechargeable battery, supports 64 to 1024 test channels, and can quickly detect continuity, open circuits, short circuits, insulation faults, and resistance issues. Its lightweight, handheld design makes it ideal for field testing and maintenance applications.

BKWH High Voltage Tester

BKWH high voltage wiring harness tester series is mainly for new energy vehicle high-voltage wiring harness testing equipment. New energy vehicles generally use 300V~600V or even higher voltage platform. The high voltage cable is used to connect the high-voltage battery, inverter, air conditioning compressor, three-phase generator and motor, so as to achieve the transmission of power and energy. Due to the high voltage, new energy vehicles require test equipment to provide up to DC6000V/AC5000V test signal output.

BKWF Four Wire Kelvin Tester

BKWF Four Wire Kelvin Tester is a high-precision cable and wire harness tester that uses 4-wire Kelvin measurement technology to provide highly accurate resistance and continuity testing down to milliohm (mΩ) levels. It also performs open/short circuit, insulation resistance, and high-voltage (Hipot) tests, making it ideal for quality control of critical wiring harnesses.

BKWA Electric Vehicle Tester

BKWA Electric Vehicle Tester is a precision tester designed for automotive and EV wire harness testing. It can detect continuity, short circuits, open circuits, miswires, resistor and diode faults, and connector air-tightness, helping ensure harness quality and reliability. It supports up to 10,240 test points, imports wiring data from Excel, and provides automatic test records and barcode traceability. BKWA electric vehicle tester is designed for automobile wire and harness test. It supports all kinds of continuity test stations, with built-in barcode printer, scanner and other equipment software.

BKWD Distributed Cable& Harness Testing System

BKWD Distributed Cable & Harness Testing System is a testing solution designed for large-scale cable and wire harness systems used in equipment such as aircraft, high-speed trains, and other large machinery. It enables efficient testing of cables distributed across different sections of the equipment, helping verify wiring integrity, connectivity, and overall harness quality.
