UNIT UT139S is an advanced digital multimeter designed for electricians, service technicians, and users who expect high accuracy and safety in measurements. The device is equipped with True RMS technology, ensuring reliable results even when measuring non-sinusoidal signals.


The multimeter offers automatic range selection (Auto Range), which significantly facilitates and speeds up work, as well as the option for manual range setting for more precise applications. Thanks to the NCV (Non-Contact Voltage) function, quick, non-contact detection of voltage presence is possible, increasing user safety when working with electrical installations.
The device allows for a wide range of measurements, such as DC and AC voltage, current, resistance, capacitance, frequency, and temperature. Additional features, including diode testing and continuity testing with audible indication, make the UT139S a versatile diagnostic tool.


A clear, backlit LCD display provides good visibility of results even in poorly lit areas. The ergonomic housing and solid construction make the multimeter resistant to intensive use and ideal for both professional applications and advanced home projects.
