UNI-T UT526 Multifunction Tester

Product detailed description

UNI-T UT526 Multifunction Tester
The UT526 instrument is a universal measuring and testing instrument for carrying out inspections of electrical appliances. It allows checking the equipment of current protectors, measuring the resistance of the grounding loop, measuring the insulation resistance, measuring the frequency of AC voltage, and measuring DC and AC voltage. The instrument is newly designed in a rugged enclosure with new analog, digital and microprocessor circuits.
This instrument has been designed, manufactured and tested to IEC61010 (Safety Requirements for Electrical Equipment) safety standard in the CATIII 600V overvoltage category. It fully complies with STN EN 61557 for measuring insulation and transient resistance.
