The UNI-T digital clamp multimeter UT203 is a 3¾ digits instrument with steady operation, fashionable structure and highly reliable measuring. The Meter uses a large scale of integrated circuit with double integrated A/D converter as its core, and contains a full range overload protection.
Besides the quality, the measurement devices distinguish by their ease of use, good legibility of the display and sophisticated measurement functions. UNI-T digital multimeters also fulfill the important details of everyday measuring, such as the almost immediate response of the continuity test, reliable measurement results, and conservative use of the battery. If you have ever worked with a digital multimeter from one of the various cheap manufacturers, you are familiar with problems such as continuity tests taking several seconds, noticeable deviation of measurement results if the battery is low, and rapid battery drain...
