UNI-T True RMS Digital Multimeters UT139C

UNI-T UT139C Electrical Digital LCD True RMS Multimeters Handheld Multimetro Tester Ammeter


True RMS Digital Multimeters UT139C
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.
