2/6
The UT-191T is a universal digital meter used to measure: voltage, current,
resistance, capacity, frequency, temperature and checking the correct operation
of diodes. The meter has the function of automatic change of measuring ranges,
as well as the relative measurement mode.
The device meets the IP65 tightness class.
