UNI-T UT595 Multifunction Installation Tester – Insulation 250/500/1000V to 1000MΩ, Loop and Line Impedance, RCD Trip Time, PFC to 26kA, Phase Sequence, 9999 Count
Pickup available at Digilog Electronics
Usually ready in 2 hours
The UNI-T UT595 multifunction installation tester brings a full electrical-installation test suite into one 9999-count instrument: insulation resistance at 250V, 500V and 1000V up to 1000MΩ, 200mA low-resistance continuity, line and loop impedance from 0.01Ω to 2000Ω with prospective fault current to 26kA, RCD trip-time and ramp testing, phase sequence and AC voltage to 440V.
The UT595 is the upper model of the UT590 series, extending RCD trip-time coverage with ×2 I△n test ranges. With connection checks displayed in real time, one-key storage of RCD results and a 0°/180° phase-angle option to catch the fastest trigger time, it is built for electrical contractors and inspectors certifying installations.
Key Features
- Insulation to 1000MΩ ⚡ — 250V / 500V / 1000V test voltages at ±10%, ±(5%+5) accuracy.
- 200mA continuity testing 🔧 — 0.00Ω~199Ω range with over 200mA test current for earth continuity.
- Loop and line impedance ✅ — 0.01Ω~2000Ω with 20A test current and PFC/PSC to 26kA.
- Non-trip loop impedance 🔧 — 1.00Ω~2000Ω at 15mA so you can test without tripping the RCD.
- Full RCD trip-time testing ⚡ — 10/30/100/300/500mA at ×1/2, ×1, ×2 and ×5 I△n, plus ramp testing.
- 0°/180° phase angle option ✅ — detect the fastest trigger time; half-wave and 30 s count-down modes.
- Phase sequence and missing-phase test 🔧 — 100V~440V, forward and reverse rotation display.
- 9999-count LCD with analogue bar 🔋 — white backlight, data storage and auto power-off.
