UT139B digital multimeter new versatile multimeter from the company unit with the function True RMS. With the help of this device makes measuring AC and DC current, voltage, resistance, capacitance, frequency and duty cycle, diode conduct tests, file transfer electric circuits. The device enables to measure the true RMS value (True RMS) in the frequency range 45 Hz 400 Hz and the opportunity to work with the frequency converters (VFD). Unlike other models of multimeters series UT139 unit are powered by two batteries AA 1.5 V.
