The Uni-T UT593AU is a high-performance, multifunctional electrical tester engineered specifically for the Australian electrical market. It combines several critical testing functions into a single, rugged unit, allowing electricians to perform insulation resistance, RCD trip time and current, loop impedance, and voltage tests with ease. This versatile tool is essential for ensuring that electrical installations are safe, functional, and fully compliant with local regulations.

Built to withstand the demands of professional fieldwork, the UT593AU features a large 9999-count LCD display with an analog bar and a bright backlight for clear visibility in dark environments. With its comprehensive range of test modes—including ramp testing for RCDs and phase sequence detection—this device is designed to find faults faster and provide reliable data for both residential and commercial safety inspections.

Why It Matters

Compliance with AS/NZS standards is non-negotiable for Australian electrical work. The UT593AU provides the accuracy and reliability needed to certify that every circuit, RCD, and grounding system is operating within safe limits, protecting both the electrician and the end-user from potential hazards while streamlining the documentation process.

Tradie Pro Tip

Use the ramp test mode when dealing with nuisance tripping. By slowly increasing the current, you can identify if an RCD is tripping prematurely due to existing leakage in the circuit, helping you differentiate between a faulty breaker and a cable leakage issue.
