UNI-T Digital Multimeter UT131B

Description
The new generation of UNI-T UT131 multimeters offers a higher standard of measurement in the more affordable digital multimeter category. Innovative and industrial design with protective sleeve ensures the multimeter's impact and fall resistance from up to two meters. The new LCD layout is clearer and more practical for all users, plus a backlight option. UT131 series multimeters ensure safe handling and measurement and are classified as safety category CAT II (double insulated appliances) and are designed for measurements in circuits up to 250V / ac or dc. The display range is ± 1.999. The protection of the current ranges is carried out by fast-blow fuses (10A fuse 10A / 250V; mA / µA fuse 200mA). The multimeter is powered by two AAA 1.5V alkaline batteries.

The UT131B model in the UT131 series is characterized by manual selection of the measuring range within the given measurement of Vst, Vss, mVss / st, resistance, buzzer, semiconductors, µAss / st, mAss / st, Ass / st plus battery testing with load.
