The UNI-T UT590 Series Multifunction Installation Testers are professional electrical testing instruments designed for electrical installation verification, commissioning, inspection, maintenance and fault finding.
Combining multiple essential electrical installation tests in one portable instrument, the UT590 Series can perform insulation resistance, low resistance continuity, line impedance, loop impedance, prospective fault current (PFC), RCD testing, phase sequence and AC voltage measurements.
Available as the UT593 and UT595, the series is particularly suitable for electricians, electrical contractors, commissioning technicians, facility maintenance teams and electrical inspectors who require a versatile instrument for day to day installation testing.
With a 9999-count display, 250V/500V/1000V insulation testing, >200mA continuity testing, non-trip loop testing, multiple RCD test modes and real-time connection checking, the UT590 Series provides a practical all in one solution for professional electrical installation work.
