Detection and measurement for safer operations

The Catex™ 3 offers top performance in gas concentration and atmosphere measurement, as well as leak surveys and localization. Measurements are highly stable and reliable, with built-in thermal compensation and IR sensors that are totally immune to poisonous compounds present in methane or propane. Continuous self-diagnostics (failsafe) stop readings in the case of a serious error and prevent false measurements.
