Oldham CTX 300 Gas Detector

  Detects O2, CO2, toxic and refrigerant gases
  4-20 mA output analog transmitter with optional backlit display
  Plug-in and pre-calibrated sensors
  Available with electrochemical, infrared or semi-conductor sensors
  More than 30 different sensors are available to detect most toxic gases in the industry
  Available in an infrared version for CO2
  EN14624 compliant with regards to R134a monitoring
  Oxygen detector for commercial or industrial applications in unclassified areas

When hazardous levels of toxic gases or oxygen threaten the safety of an unclassified area, the CTX 300 oxygen detector can satisfy the most demanding safety requirements.

The CTX 300 detector is designed to detect oxygen, toxic and refrigerant gases, and also uses a new sensor for CO2 detection over three different ranges: 0-5000 ppm, 0-5% vol. and 0-100% vol.

The CTX 300 transmits data in record time. With a wide range of sensor options, it has the flexibility to protect many potentially hazardous environments.

Maintaining the unit is easy with pre-calibrated sensors and an optional LCD display.
