UNI-T UT139S True RMS Digital Multimeter — professional measuring instrument for accurate measurement of voltage, current, resistance, frequency, capacitance and temperature. Due to its wide functionality and high accuracy, the instrument is suitable for both electricians, service engineers and home craftsmen.
The multimeter is equipped with the True RMS function, which provides accurate measurement of alternating voltage and current even with a distorted signal shape. The instrument also has a non-contact voltage detector (NCV), which allows you to quickly determine the presence of alternating voltage without direct contact with the wire.
UNI-T UT139S — a universal and reliable tool for professional electrical measurements.
Principle of operation:
The multimeter measures electrical parameters using built-in high-precision electronic circuits. The results are displayed on a large backlit LCD display.
Thanks to the analog graphic scale, the user can quickly track the signal change in real time, which is especially convenient when diagnosing electronic circuits.
Advantages:
- 📟 6000 count display with backlight
- 📊 Analog graphic scale for quick signal analysis
- ⚡ True RMS — accurate measurements of alternating signals
- 📡 NCV — non-contact voltage detection
- 🌡 Temperature measurement up to 1000°C
- 📉 Low pass filter (LPF) for accurate measurements
- 🔌 LoZ mode to eliminate phantom voltage
- 🔊 Audible continuity test
