The Kyoritsu 6516BT Multifunction Tester is a versatile all in one electrical installation tester designed for professional electricians, switchboard builders, inspectors, and maintenance technicians who require fast and reliable verification of electrical installations in accordance with safety standards.
Combining multiple testing functions into a single portable unit, the 6516BT simplifies commissioning, troubleshooting, and routine inspection work across residential, commercial, and industrial electrical systems. The built in Bluetooth functionality allows test results to be transferred wirelessly to a smartphone or tablet for easier reporting and record management in the field.
The instrument supports insulation resistance testing, continuity testing, loop impedance, PSC/PFC measurement, RCD testing, voltage checks, and phase rotation verification, making it an ideal solution for complete installation testing and compliance verification. Its rugged design, intuitive interface, and large backlit display make it practical for both site and maintenance environments.
