UNI-T UT131B multimeter – unboxed

We provide a 3-year warranty on this product. The UNI-T UT131 series of multimeters offers a high standard of measurement within the affordable digital multimeter category. The innovative, industrial design, featuring a protective casing, ensures the multimeter can withstand impacts and drops from heights of up to two metres. The new layout of the LCD display is clearer and more practical for all users; the display also features a backlight. The UT131 series multimeters ensure safe handling and measurement; they are classified as CAT II safety category (double-insulated appliances) and are designed for measurements in circuits up to 250 V AC or DC. The display range is ±1.999. The current ranges are protected by fast-acting tubular fuses (the 10 A range by a 10 A/250 V fuse; the mA/µA range by a 200 mA fuse). The multimeter is powered by two 1.5 V AAA alkaline batteries.

The UT131B model in the UT131 series features manual selection of the measurement range within the given measurement modes: Vst, Vss, mVss/st, resistance, buzzer, semiconductors, µAss/st, mAss/st, Ass/st, as well as 1.5V, 9V and 12V battery testing with a load.
