UT-502A Insulation Resistance Meter
The Insulation Resistance Meter delivers dependable, high‑range testing accuracy for demanding electrical environments. This Insulation Resistance Meter helps professionals diagnose insulation issues quickly and confidently.
Insulation Resistance Meter – Benefits for You
✅ Quickly identify insulation faults so you can prevent costly downtime and safety hazards.
✅ High measurement range ensures you can assess everything from small systems to large industrial equipment with confidence.
✅ Backlit display keeps critical data visible so you can work efficiently in dim or low‑light spaces.
✅ Automatic power functions save battery life so the device is ready whenever you need it.
✅ Robust construction withstands tough field conditions so you can rely on it during daily operations.
✅ Integrated warning alerts notify you of high voltages so you stay protected during testing.
✅ Smooth, intuitive controls simplify operation so even complex tests feel straightforward.
Take your electrical diagnostics to a more reliable level with a meter designed for professional precision.
The UT-502A offers a wide insulation resistance range of 0 MΩ to 20 GΩ, giving technicians the flexibility required for residential, commercial, and industrial work. It delivers consistent results using selectable test voltages of 500 V, 1000 V, and 2500 V, allowing you to match the measurement settings to the system you are examining.
Accuracy remains dependable across the scale, with refined performance at low, mid, and high resistance values. Open‑circuit voltage remains stable, and controlled test currents help maintain reliable readings across a variety of conditions.
This meter also supports AC voltage testing from 30 V to 750 V, along with low‑resistance measurement capabilities for continuity checks and system troubleshooting. Automatic range switching makes each test smoother, removing unnecessary guesswork.
The device includes RS‑232 and USB connectivity for convenient data logging, helping you store and review measurements over time in a clean, organized workflow.
Additional functions such as polarization index testing and dielectric absorption measurements offer advanced diagnostic tools for insulation health evaluation. The reset option for low resistance readings keeps the device ready for rapid repeated use.
Operating between 0 °C and 40 °C with up to 85% relative humidity, the meter performs well in typical field environments. Six AA batteries power the unit, providing portable functionality without reliance on external power sources.
With its ergonomic shape, clear LCD backlight, and sturdy build, the UT-502A supports long work sessions and dependable readings, making it a valuable asset in any technician’s toolkit.
