GMS-IV is a low-noise measuring preamplifier for monitoring gas insulated switchgear (GIS).

This amplifier technology allows to detect the broadband transmissions small defects or impurities in the GIS. Thus, vulnerabilities can be detected early and damage can be avoided. The amplifiers are powered via the coaxial cable at the output. A protective circuit at the input prevents the destruction by excessive input power.

We offer:
+ Input Protection
            to prevent damage to the electronics
+  Status LED
             simple optical status control
+  Extremely versatile through very large bandwidth
             measure unaffected by different noise sources
+  Models ranging from standard to high sensitivity
             whatever requirements you have we have a suited model

Trusted by manufacturers and commissioning organisations around the world.
