Sending in your gas detector for service is quick and easy.

After receiving your unit, CTI will process it within one business day (pending unforeseen repairs) and send it back with a calibration certificate. Units sent in will be function-tested for common issues that require repairs. We keep most repair parts on hand to quickly calibrate gas detectors and allow our customers to return to work with peace of mind.
