The UNI-T UT139C is a 5999-count True RMS digital multimeter for professional electrical and HVAC maintenance. It measures AC/DC voltage and current, resistance, capacitance, frequency, duty cycle and temperature, with VFC, NCV and optional 40 A current-sensor support.

Key Features

  • True RMS measurement for AC voltage and current
  • Measures AC/DC voltage up to 600 V and AC/DC current up to 10 A
  • Measures resistance, capacitance, frequency, duty cycle and temperature
  • VFC mode for variable-frequency environments and NCV for non-contact voltage detection
  • 5999-count display with automatic/manual ranging and MAX, MIN, REL and data hold modes
