The insulation resistance tester UNI-T UT511 is a digital measuring device designed for both electronic fields. Enables the measurement of high resistances up to 10 GOhm at a test voltage of 1000 V. In addition, you can measure AC and DC voltages as well as low resistances with this meter. Among the many additional functions, the dielectric absorption test, polarisation indexing and comparator function are worth highlighting. This model complies with IECG1010 standards.
