GLP2-R Resistance Testers
Single-function and multifunction testers for resistance testing
Our resistance testers are based on proven GLP2 technology and are optimized for both individual and combined testing tasks.
The range of options extends from
- Resistance tester
- Resistance and Insulation Resistance Tester
- AC/DC Resistance, Insulation Resistance, and High-Voltage Tester
Switching between test methods occurs automatically, ensuring a smooth process. In addition, the test points can be flexibly expanded, either via an integrated relay matrix or through external matrix modules. A particularly convenient feature is that the relays can be controlled directly from the test unit. This simplifies setup and speeds up the testing process.
Typical applications
