The Oldham CTX 300 can detect O2, CO2, toxic and refrigerant gases. Choose from a range of sensors (infrared, electrochemical, semiconductor) according to your application needs. It is also available with or without display.

Sensor replacement does not require any special menu access. Just replace the sensor without even powering down the transmitter.

As the only consumable element, the CTX 300 sensor is easily replaceable. New sensors come pre-calibrated from the factory. So during the sensor exchange, no calibration gas is required, nor are the detector or remote central controller adjustments necessary. Oldham is a Teledyne brand.
