Our Services

What Sets CTI Apart From the Competition?

Customer Service Always Wins

CTI is large enough to meet all your gas detection needs, but small enough to know your name. We answer every phone call and can quickly connect you with the expert employee you need. CTI gives you access to the engineers and technicians who design and service the equipment. Quick response and personal service is our top priority.

Our Sensors Thrive Where Others Fail

CTI equipment is designed and built to thrive in harsh industrial environments. Extreme temperature, wet and dirty environments, and the presence of other gases do not affect the reliability of our sensors and alarms.

Prevention of False Alarms

False alarms foster complacency, cost money, and irritate employees. CTI specifically designs our equipment to prevent false alarms. Reliability and accuracy are our goals.
