Please note - Product designs and specifications are subject to change without notice. The user is responsible for determining the suitability of this product.

• Available with electrochemical, infrared or semi-conductor sensors
• More than 30 different sensors are available to detect most toxic gases in the industry
• Available in an infrared version for CO2
• EN14624 compliant with regards to R134a monitoring
• Oxygen detector for commercial or industrial applications in unclassified areas

The CTX 300 detector is designed to detect oxygen, toxic and refrigerant gases, and also uses a new sensor for CO2 detection over three different ranges: 0-5000 ppm, 0-5% vol. and 0-100% vol.

The CTX 300 transmits data in record time. With a wide range of sensor options, it has the flexibility to protect many potentially hazardous environments.

Maintaining the unit is easy with pre-calibrated sensors and an optional LCD display.
