UNI-T UT-511 Insulation Resistance Meter for Precise Electrical Testing
The Insulation Resistance Meter delivers dependable accuracy for demanding electrical inspections. This insulation resistance meter helps you verify system safety with confidence.
Insulation Resistance Meter – Benefits for You
✅ Quickly assess insulation health so you can identify issues before they become hazards.
✅ Clear readings help you make confident decisions even in challenging lighting conditions.
✅ Reliable performance supports smooth workflows so you can stay focused on the task.
✅ Intuitive controls streamline testing, letting you work efficiently without guesswork.
✅ Safety indicators keep you aware of voltage conditions so you can handle every test with caution.
✅ Robust construction ensures dependable use in the field, giving you long-term value.
✅ Handy data storage lets you review past measurements so you can compare results over time.
Strong performance and dependable accuracy make this tool an excellent partner for electrical diagnostics.
The UT-511 is designed for technicians who need trustworthy readings across a wide range of insulation values. It supports test voltages of 100 V, 250 V, 500 V, and 1000 V, allowing you to adapt easily to different systems and environments.
The device measures insulation resistance from 0.1 MΩ to 10 GΩ, giving you the flexibility required for both routine checks and more demanding applications. Its graphical display with backlighting provides clarity during testing, and the built-in safety alerts help you stay aware of high-voltage conditions.
Accuracy remains consistent thanks to carefully engineered measurement ranges. Resistance from 100 kΩ to 100 MΩ maintains precision within ± (3% + 5), while readings above 100 MΩ achieve ± (5% + 5). This allows you to trust each result even when working on sensitive electrical installations.
The open circuit voltage reaches the test voltage plus 20%, and the meter uses a controlled test current between 1 mA and 1.2 mA depending on the selected level. For short-circuit situations, it delivers approximately 2 mA, maintaining safe operating parameters.
Beyond insulation testing, it also measures both AC and DC voltage. AC ranges from 30 V to 750 V with ± (2% + 3) accuracy at 1 V, while DC voltage spans 30 V to 1000 V with similar precision. Automatic range switching reduces manual adjustments, helping you complete tasks more quickly.
Connectivity is straightforward thanks to its RS-232 and USB interfaces, making it easy to transfer results. You can store up to 18 measurements internally, which is useful when documenting tests on multiple circuits or locations.
The meter includes several practical features such as comparative testing, polarization index measurement, and a maximum test duration of 30 minutes. Its sturdy and compact build enhances portability, while the large LCD ensures visibility. A low-battery alert helps you avoid interruptions mid-task.
Designed to operate reliably between 0 °C and 40 °C with up to 85% relative humidity (non-condensing), this model performs well in typical work environments. It can run on eight 1.5 V R14/LR14 batteries or an optional 15 V DC adapter.
With dimensions of 202 × 155 × 91 mm and a weight of 0.92 kg, it fits comfortably into tool kits. The package measures 330 × 315 × 120 mm and weighs 3.18 kg, offering generous protection during transport.
This instrument is well-suited for electricians and maintenance personnel who require reliable insulation testing across a range of electrical systems. Its thoughtful design helps reduce downtime and improve workflow efficiency on the job.
Watch the product in action on YouTube to see how it performs in real testing scenarios.
