UNI-T UT139S multimeter
Details
The UNI-T UT139S is a true-RMS multimeter that can measure up to 600V AC/DC, with multiple high-end features. The small auto-ranging multimeter is designed for all the needs of an electrical technician. The high contrast in combination with the blue digits, ensures that the 6.000 counts display stays easy to read no matter the lightning condition. The multimeter features an adjustable brightness, to ensure readability in every condition. In addition, the display has a 31-segment bar graph displaying the range that was selected automatically.
Moreover, the meter is provided with a rubber case that protects it against falling or other external influences. The meter is equipped with electric field detection and LoZ, which presents a low impedance input to the circuit, which can be used to detect 'ghost voltages'. This device offers measurement possibilities for DC/AC voltages and currents. Additionally, the meter measures resistance, capacitance, frequency, temperature, duty cycle and diodes. The UT139S is quite similar to the UT139C, the only difference is the display and the LoZ function.
