Common questions
Which replacement sensor does it use?
CTI lists the GG-NH3-RC-EXP as the replacement sensor element for this detector. GG-EXP transmitters are target gas, sensor element and range specific, so use only the specified replacement sensor.
Specifications are based on the CTI (Calibration Technologies) product page for GG-EXP Gas Detector Explosion Proof. Confirm fit, ratings and application requirements before ordering.
