Professional Electrical Installation Testing with the UNI-T UT595
Accurate verification of electrical systems is crucial for preventing hazards, protecting equipment, and certifying installations. The UNI-T UT595 Multifunction Installation Tester is engineered specifically for certified electricians, maintenance technicians, and electrical inspectors working across residential, commercial, and industrial facilities. Featuring complete compliance with European safety standards and bearing official CE certification, this instrument delivers reliable results that align with strict EU installation regulations.
Versatile Diagnostics: From Ground Continuity to Loop Impedance
Equipped with a broad array of measurement modes, the UT595 eliminates the need to carry multiple single-function meters. Its 200 mA continuity test verifies protective bonding conductors swiftly and accurately down to 0.01 Ω. When checking insulation integrity, users can toggle between 250 V, 500 V, and 1000 V DC test voltages, reaching resistance measurements up to 1000 MΩ. The integrated loop impedance mode features both a 20 A high-current test for raw line/loop analysis and a dedicated 15 mA non-trip setting that prevents nuisance tripping of active residual current devices during live circuit diagnostics. Real-time calculation of Prospective Fault Current (PFC) and Prospective Short-Circuit Current (PSC) up to 26 kA ensures that circuit breakers and protection devices are sized correctly for the installation.
Advanced RCD Analysis and Phase Verification
The UT595 shines in complex RCD testing scenarios. Supporting trip current settings from 10 mA to 500 mA, it handles trip time evaluations at half-rated, full-rated, double, and five times the residual current rating (×1/2, ×1, ×2, and ×5 *IΔn). Electricians can effortlessly switch between 0° and 180° phase angles to capture the fastest trigger time, conduct half-wave or full-wave tests, or run automated 30-second countdown sequences. In addition, the instrument incorporates phase sequence verification (L1-L2-L3 clockwise/counter-clockwise rotation) between 100 V and 440 V, making it an invaluable asset when commissioning 3-phase machinery, sub-panels, and commercial distribution boards.
Durable Design for Demanding Job Sites
Housed in a rugged casing rated for CAT III 300 V environments, the UNI-T UT595 is built to withstand everyday job site handling. The large 9999-count backlit display with an analogue bar graph provides crisp readouts even in dimly lit switchboards. With intuitive one-touch test triggering, a remote-control test probe, comprehensive connection status monitoring, and an automatic power-off function to preserve battery life, the UT595 streamlines verification workflows from initial installation sign-off to recurring safety audits.

Safety Instructions
⚠️ Safety and Warning Instructions for Measurement and Testing Equipment
Before using our measurement and testing equipment (such as multimeters, current/ground fault clamps, voltage testers, laser and environmental measuring devices, laboratory power supplies, oscilloscopes, and testing and inspection tools), please be sure to observe the following warnings:
Electrical Safety & Voltage Hazards (Danger to Life)
- Risk of electric shock: Check devices and test leads for damage (e.g., cracks in the insulation, exposed wires) before each use. Damaged devices or cables must never be used!
- Measurement categories (CAT): Pay attention to the permissible overvoltage category (e.g., CAT III 600V, CAT IV 300V). Never use the devices in mains circuits that exceed the specified category or the maximum rated voltage/current.
- Voltage-free condition: Perform resistance, continuity, diode, or capacitance measurements exclusively on voltage-free circuits. Capacitors must be discharged before measurement.
- Fuses: Replace defective fuses in multimeters exclusively with the exact same type (usually high-resistance ceramic fuses with the same voltage and current specifications). Never bypass them!
- Grounding & Lab Power Supplies: Operate mains-powered test equipment (e.g., oscilloscopes, lab power supplies, function generators) only from properly grounded outlets. Incorrect voltage or current settings on laboratory power supplies can destroy connected components, which can lead to fire or explosion (e.g., of electrolytic capacitors).
Laser Radiation & Optical Hazards
- Eye injuries: Many devices (laser rangefinders, infrared thermometers, tachometers) use aiming lasers. Never look directly into the laser beam and do not point it at people or animals.
- Reflections: Caution around reflective surfaces! The laser beam can be deflected and unintentionally strike the eye.
- Risk of glare: Borescopes and inspection cameras often have very bright LEDs. Do not look directly into the light source.
Heat, fire hazard & environmental conditions
- Risk of burns: When using thermal imaging cameras or contact thermometers to measure hot components (e.g., in industrial settings or on engines), there is a risk of accidentally touching hot surfaces. The measuring device itself does not protect against the heat of the test object.
- Wetness & Moisture: Never use electrical measuring instruments in wet, damp, or extremely condensing environments unless they explicitly have a corresponding IP protection rating. Moisture inside the device can lead to fatal short circuits.
- Explosion hazard: The devices are generally not EX-protected. Do not use them in environments containing explosive gases, vapors, or dust.
Mechanical hazards & handling
- Rotating machine parts: When using tachometers, anemometers, or stroboscopes on running machines, there is an extreme risk of entanglement. Maintain a safe distance and do not wear loose clothing, have your hair down, or wear dangling jewelry. Ensure that test leads do not come into contact with moving parts.
- Falls & Equipment Damage: A dropped measuring device (e.g., multimeter, insulation tester) may be internally damaged, which means protection against electric shock is no longer guaranteed. If in doubt, have the device tested at 230V before using it again.
- Magnetic fields: Some devices or mounts contain strong magnets. Keep them away from pacemakers, magnetic data storage devices, and sensitive electronics.
General Information & Health
- Technical expertise: Work on electrical systems (especially those operating at 50V AC / 120V DC or higher) must only be performed by appropriately trained professionals.
- Batteries: Remove batteries/rechargeable batteries if the device is not used for an extended period of time to prevent damage and burns caused by leaking battery acid.
- Children: These high-precision test and measurement devices are not toys. Keep them out of the reach of children.
