UNI-T UT139C True RMS Digital Multimeter Auto/Manual Range Tester 6000 Count Voltmeter Ohmmeter Temperature Frequency Meter
UT139 series is high reliability, high security, automatic measurement range modern digital multimeters . With synchronous display function with super large screen digital and high resolution analog pointer, full range overload protection and unique appearance design; And with the frequency converter VFD measurement function, can be stable measurement of high frequency interference signal frequency or current situation;
Combined with true RMS measurement, data storage , relative measurement, maximum / minimum, under pressure prompt, backlight and auto power off function, which becomes more superior performance of electrical instruments. It is suitable for measurement of smelting, communication, manufacturing, petroleum, national defense, university, electric power, chemical industry and other industries. It’s an ideal tool for the maintenance and repair of the circuit , power equipment.
Non-contact voltage Test, Principle of magnetic or electric field sensors to determine if voltage is present, similar to induction test pen function without direct contact and test probes charged. Used to find buried live wires inside the wall or find a buried wire disconnected.
VFC functions: filter out high frequency jamming signal, accurate measurement data. For variable-frequency motor application failures that may occur and effective detection and troubleshooting.
