Product description
UNI-T UT139S is a professional True RMS multimeter developed for electricians and service technicians. The multimeter features a CAT III 600 V safety rating and supports both automatic and manual ranging. The black EBTN display provides high contrast and excellent readability, even in dark environments.
The instrument features NCV functionality for non-contact detection of electrical fields as well as a LoZ function for AC voltage, helping to reduce the influence of ghost voltages. The built-in 31-segment analog bar graph provides fast and clear visual feedback during measurements. True RMS technology enables accurate measurements even on non-sinusoidal signals.
