Whether you need an infrared or catalytic bead sensor to detect combustible gases or an electrochemical sensor for a toxic environment, the Meridian universal gas detector utilises a single detector head to accept all sensor types easily. There is no requirement for different personality boards in the gas detector or other detector heads to make the instrument behave as a combustible or toxic gas detector.

The Meridian gas detector accepts all sensor types in one detector. Installation of the sensor is a simple plug-and-play action. Attach the specific toxic or combustible sensor to the universal detector head, and the Meridian gas detector will automatically determine the type of gas to be detected. Several ranges are available with each gas sensor to meet your specific application.

You can perform sensor replacements without powering down the instrument or declassifying an area. Sensors provide reliable performance even in harsh temperature and humidity environments with minimal drift. High specificity means less interference from other gases, reducing cross-sensitivity and the likelihood of false alarm.

All accessories fit the universal detector head, no need to purchase different accessories for toxic and combustible monitoring. Global approvals allow deployment anywhere in the world.

Supports industry-standard communication protocols, including 4-20 mA analogue, MODBUS, and wired HART.

  • Single detector head for all sensor types
  • Full range of combustible and toxic sensors
  • Voted Best Industrial Hygiene – Fixed Permanent System
  • Approvals: IECEx, cCSAus, ATEX, INMETRO INDUSTRY CANADA, CE, SIL-2 (Third Party Certification by TUV-Rheinland)
