Fixed Gas Detector
CTX
300
FIXED GAS DETECTOR
 Quick response time
 Pre-calibrated
sensor modules
 One man calibration
 Local display (optional)
 Durable in harsh
environments
The detection of toxic gases or oxygen
depletion requires the installation of detectors
satisfying demanding requirements. The CTX
300 range is designed for all safety needs in
unclassified areas.
Flexibility and reduced
maintenance
The CTX 300 transmits the relevant data in
record time, covering all hazard situations and
providing extreme flexibility by way of a wide
range of sensors.
Sensors integrating zero and sensitivity
parameters are used so that maintenance is
quick and safe.
Equipped with pre-calibrated sensors, display
unit and adjustment devices, the CTX 300
transmitter can be maintained by one person.
Satisfying your safety requirements means
making genuine technical breakthroughs as
well as providing clear economic value.
The principle of the pre-calibrated sensor unit
allows maintenance by a single person and
significant reduction in costs.
Compliance with standards
• Compliance with European standards
• EMC in compliance with directives
