UNI-T UT18B Max multimeter
Details
The UNI-T UT18B Max is a True-RMS multimeter with many handy features for measurements. It can measure AC/DC voltages up to 1000V and current up to 10A. Since the meter is certified to meet CAT-III 600V standards, it is safe and reliable for residential and industrial applications. The included K-type thermocouple for measurement of temperatures from -55℃ to 500℃ makes this multimeter stand out compared to other multimeters at this price/feature set.
A unique feature of the UT18B Max is that it can perform variable frequency drive (VFD) measurement with a high interference rejection, as well as LED testing with automatic polarity detection. Furthermore, there are protection features, such as a mis-plug alarm, full-range input protection, and an indication for over-voltage/over-current.
