UNI-T UT139C цифровой мультиметр авто диапазон True RMS конденсатор тестер 6000 счетчик вольтметр измеритель температуры

Цифровые мультиметры серии UT139 с истинным среднеквадратическим значением имеют функцию VFC, которая позволяет LPF иметь более высокую точность в условиях высокочастотного интерфейса. Функция NCV также может эффективно проверять состояние электричества без контакта с измеряемым объектом.

Feature

1. MAX/MIN/REL modes

2. Data hold, LED backlight, auto power off

3. Full range protection (600V)

4. True RMS

5. NCV

6. Auto/manual ranges selectable

UT139 series is high reliability, high security, automatic measurement range modern digital multi meters . 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.

VFCfunctions: filter out high frequency jamming signal, accurate measurement data. For variable-frequency motor application failures that may occur and effective detection and troubleshooting.
