CTex-Kit

Upgrade Kit for CT Infrared Pyrometers in Hazardous Areas

The CTex Upgrade Kit transforms a standard Optris CT sensor into an explosion-proof version, ensuring safe operation in hazardous environments. This kit includes Zener double barriers, providing essential protection in explosion-prone areas (ATEX compliant). The upgrade maintains the same high-performance characteristics as the CTex LT series. The kit ensures secure and precise remote temperature monitoring with the same reliability as the original CT series. This comprehensive upgrade instills confidence in safety, making it indispensable for critical applications in dangerous settings.
