Model UT522 is a professional meter designed for measuring ground resistance and voltages on grounding systems and lightning protection installations.
The device is dedicated to installers, service providers, energy companies, and for monitoring lightning protection systems. Thanks to its wide measurement range and thoughtful design, it will perform well in both fieldwork and inspections in industrial plants.
Key features and characteristics
- Measurement of ground resistance in a 3-wire configuration (more accurate method) and 2-wire configuration (faster/simplified)
- Resistance measurement range: from 0 Ω to 4 000 Ω in three ranges.
- AC voltage measurement on the ground or between grounding points in the range of 0‑400 V.
- Clear LCD screen (up to 4000 counts) with backlight - facilitates reading in low light conditions.
- “Data Hold” function (freezing the last result), backlit display, low battery indicator.
- Automatic shutdown of the device after a certain period of inactivity - battery saving.
- Memory storage: ability to record up to 20 measurements in the device's internal memory.
- Design adapted for “field” work: durable housing, complete set of accessories included (wires, auxiliary grounds)
Applications
- Measurement of ground resistance of lightning protection installations, lightning protection systems, grounding of networks and devices in the energy sector.
- Monitoring the condition of grounding in industrial plants, telecommunications, network infrastructure.
- Voltage measurement on the ground - identification of irregularities in the grounding installation.
- Field service and inspections - thanks to the portability of the device and additional functions.
Parameters:
- Ground resistance measurement: 0 - 40 Ω (accuracy +/-(2%+20))
0 - 400 Ω (+/-(2%+3))
0 - 4000 Ω (+/-(2%+3)) - AC voltage measurement on the ground: 0 - 400 V AC (accuracy +/-(1%+6))
- Display: Up to 4000 readings ("counts")
- Maximum ground resistance measurement range: 4000 Ω
If you need a compact, functional, and professional ground resistance meter, the UT522 model from UNI-T is a very solid option. It offers a wide measurement range, intelligent features supporting fieldwork, and a proven design. It will be suitable for installers, service providers, electrical auditors, and in facilities where monitoring of grounding and lightning protection systems is required.
