Product overview

A fixed multigas detection platform with local display, data logging and configurable industrial outputs.

Configurable fixed multigas monitoring

GTYQ-MIC-600 is a fixed multigas detection platform configurable for continuous monitoring of one to six gases at industrial installations. The installed gases, ranges and sensing principles are selected for the application.

The 2.5-inch color display shows local readings and alarms. Data logging, RS485 and 4–20 mA outputs support the monitoring point; any wireless link depends on the selected configuration.

Sampling method: Diffusion
Ingress protection: IP66
Operating temperature: -20 °C to 55 °C

ENGINEERING GUIDEHow to Define an Industrial Gas Leak Detection Project

Read guide

Industries and applications

Safety engineer checking a portable gas detector at an oil and gas process facility

Industry

Oil & Gas

Oil and gas projects span mobile worker protection, continuous release-point detection and conditioned process sampling. Define the target gases, operating conditions and site response before selecting portable, fixed or online equipment.

Explore operating context

Safety technician inspecting process equipment at a chemical facility

Industry

Chemical Processing

Define the target gases, measuring ranges and installation conditions for your process. Review the selected model's documentation and applicable certificate scope before specifying a configuration.

Explore operating context

Technician testing the atmosphere at a wastewater treatment process area

Industry

Water & Wastewater

For water and wastewater projects, describe the target gases, sampling location and expected humidity or condensation. Assess the detector configuration and any sample-conditioning requirements for the specific installation.

Explore operating context

Technician checking a process valve during a gas leak inspection

Application

Leak Detection

Industrial gas leak detection helps teams identify selected gas hazards around equipment, pipework and work areas. Portable instruments support inspection and investigation, while fixed detectors provide continuous monitoring at selected points.

Review the monitoring task

Fixed gas detector monitoring an industrial process area

Application

Area Monitoring

Fixed and online gas monitoring systems provide ongoing visibility at selected industrial locations or sample points. Detector placement, sample handling, signal integration and alarm response should work together as one monitoring approach.
