Additional Information

Description of UNI T UT139C True RMS Digital Multimeter

The UNI-T UT139C is a high-performance, auto-ranging digital multimeter designed for accurate electrical and electronic measurements. This UNI-T Multimeter is a 6000-count auto-ranging DMM built for electricians, electronics technicians, and DIY users who need accurate readings. It supports AC/DC voltage and current measurement up to 600V and 10A, along with resistance, capacitance, frequency, temperature, diode, continuity and non-contact voltage (NCV) functions. 

Backed by True RMS technology and CAT III 600V safety certification, the UT139C is a reliable choice for everyday electrical troubleshooting, industrial maintenance, and modern electronic diagnostics where inverters, UPS systems, and variable-frequency drives are involved. 

Key Features of UNI-T UT139C Digital Multimeter

  • 6000-Count LCD Display: High-resolution digital display with a responsive LED backlight for clear visibility of readings in any environment. 
  • True RMS Technology: The True RMS function allows the UT139C to measure the effective value of AC signals more accurately when the waveform is distorted or non-sinusoidal. This is particularly useful when working with switch-mode power supplies, variable-frequency drives, inverters, UPS systems, and modern electronic equipment.
  • True RMS Measurement: Delivers precise readings for AC voltage and current, even on complex non-sinusoidal waveforms.
  • Auto and Manual Range Selection: Allows convenient automatic operation or manual range control.
  • Multi-Function Testing: Measures AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, temperature (°C/°F), continuity, and diode.
  • 600V Voltage Measurement: Measures AC and DC voltage up to 600V, suitable for a wide range of electrical and electronic testing applications. 
  • 10A Current Measurement: Supports AC and DC current measurement up to 10A.
  • Resistance Measurement: Measures resistance up to 60MΩ, making it suitable for testing components and electrical circuits. 
  • Capacitance Measurement: Measures capacitance up to 99.99mF.
  • Frequency Measurement: Supports frequency measurement from 10Hz to 10MHz.
  • Temperature Measurement: Measures temperature from -40°C to 1000°C with the supplied temperature probe.
  • Duty-Cycle Measurement: Measures duty cycle from 0.1% to 99.9%, providing accurate readings for a wide range of electronic signal testing applications. 
  • Non-Contact Voltage (NCV) Detection: Allows safe identification of live electrical wires by measuring EM field intensity without direct contact.
  • VFC Function: Supports voltage and frequency conversion measurement for variable-frequency signals, making it useful for testing AC signals with changing frequencies.
  • Data Hold: Holds the displayed measurement for easier reading and recording. 
  • Auto Power Off: Helps conserve battery power when the meter is not in use. 
  • MAX/MIN/REL Modes: Useful for monitoring maximum, minimum and relative measurement values.
  • Safety Features: The UT139C is designed to CAT III 600V safety requirements and provides full-range input protection. It also includes NCV detection, allowing users to check for the presence of AC voltage without making direct electrical contact with the conductor.

Is it imported recently or was in the stock for years? (actually i diagnosed UNI-T launched it in the market in 2016 though it is not a best seller in your website while being a good DMM)

By tijek97239@archifun.com on 27 Aug 2026

Thanks for your valuable observation! The UNI-T UT139C is indeed a well-known and reliable DMM. Our current stock is imported based on demand and availability, so it isn’t necessarily stock that has been sitting for years. We also regularly monitor product condition and stock quality before dispatch.
