Testador de Voltagem Multifunções a LED - UNI-T

Description
The UT22B-EU is a simple, easy-to-use voltage tester for measuring the presence of AC/DC voltage on 230V outlets, switches and electrical appliances. This voltage tester has IP54 protection against water and dust and is designed to withstand drops from a height of 2 meters. The good thing about this product is that it doesnt need batteries, its power is supplied by the tested voltage! The UT22B allows you to distinguish voltage from 12V to 400V (by the number of LEDs) and automatically distinguish between DC and AC voltage (""+"" or ""-"" indicators are lit or both at the same time). Accuracy of voltage level indication: the corresponding LED usually lights up fully for approx. 70% to 100% of the specified range, with the exception of the 12 V AC / DC range, where it lights up already at 50% to 100% of the voltage value. The device complies with the standards: EN61326-1: 2013, EN61326-2-2: 2013, EN61243-3: 2014.
