UNI-T UT593 Multifunction Installation Testers

UNI-T UT593 Multifunction Installation Testers

The primary functions of the Multifunctional Installation Tester series multifunction testers are to test AC/DC voltage, RCD, loop/line impedance, earth resistance continuity, and insulation resistance. They can be used in the construction industry or for home electrical installation, inspection, and repair.

UT593, UT595 are the models in the Multifunctional Installation Tester Series.
