UMR-230 Handheld High-Current Micro-Ohmmeter
Product Functions:
The UMR-230 is a handheld, battery-powered micro-ohmmeter (circuit resistance tester) that uses advanced supercapacitor technology. It can measure the circuit resistance of open or GIS circuit breakers, the resistance between train frames and tracks in railways or subways, and the surface resistance of metal materials. It is suitable for any scenario requiring micro-ohmmeter testing.
Product Features:
-
High Measurement Accuracy:
The higher test current ensures greater accuracy, with a measurement range of up to 3000mΩ and a minimum resolution of 0.1μΩ. The test accuracy can reach ±(0.1% reading + 0.1% range). -
Portability:
Weighing only 0.95kg, the device is highly portable, making it ideal for high-altitude testing scenarios such as open circuit breakers. -
Fast Testing Speed:
With one-click testing and Kelvin four-wire connection, the testing process only takes a few minutes. -
Mobile Operation Software:
The device communicates with smartphones via Bluetooth, allowing for easy data export and report generation with a single click.
Application Areas:
- Power grids
- Subways
- Railways
- Nuclear power plants
- Hydroelectric plants
- Wind and solar energy facilities
- Electrical testing companies
- Manufacturing enterprises
