UNI-T UT502A Megger Insulation Resistance Tester 2500V
The UNI-T UT502A presents a durable and dependable persona from the first glance. Encased in a sturdy housing capable of enduring demanding environments, it’s built to function smoothly outdoors and onsite. The sizable backlit display ensures readings remain easily visible even in low-light scenarios, while intuitive controls and a clear rotary dial keep navigation straightforward under pressure.
Capable of delivering test voltages up to 2500 V and measuring insulation resistance across an impressive range (up to 20 GΩ), the UT502A empowers technicians to handle high-voltage insulation diagnostics with assurance. It provides essential assessment tools such as Polarization Index and Dielectric Absorption Ratio testing, giving a complete perspective on insulation health. Automatic discharge and real-time high-voltage warnings boost both safety and workflow.
This tester effortlessly merges precision with efficiency. Auto-ranging simplifies configuration, while audible and visual alerts like buzzer alarms and warning lights help catch anomalies early. Its continuity mode, overload indicators, and return-to-zero functionality for low-resistance tests further enhance accuracy and ease of use. Altogether, the UT502A balances advanced diagnostics with intuitive operation in a professional-grade package.
Features:
- Backlit 2000-count LCD display with overload indication.
- Auto discharge function for safety after testing.
- Continuous low-resistance measurement with return-to-zero capability.
- Integrated PI (Polarization Index) and DAR (Dielectric Absorption Ratio) diagnostics.
- Auto-ranging and low battery indicator for seamless use.
- Audible buzzer and red warning light for high-voltage alerts.
- Auto power-off to preserve battery life.
