Fixed Gas Detectors for Continuous Area Monitoring

Fixed gas detectors continuously monitor a selected location for gas hazards and can connect to alarms, relays or gas control panels. They are used in process plants, storage areas, laboratories, utilities, charging rooms and other high-risk zones.

Quick guide: Choose fixed gas detectors by target gas, sensor technology, mounting point, alarm output, hazardous-area rating, maintenance access and calibration routine. Placement should reflect gas density, ventilation and likely leak source.

How to Select Gas Detection Equipment

Design factor	Why it matters	Typical use
Target gas and sensor	Determines detector type and alarm thresholds	LEL, toxic gas, oxygen or VOC monitoring
Mounting location	Affects response time and reliability	Leak source, breathing zone or ventilation path
Panel integration	Controls alarms and shutdown logic	Plant rooms and process areas

Calibration, Bump Test and Compliance Notes

Gas detection should be part of a written work procedure, not a standalone device purchase. Identify the gases, test before entry where required, maintain instruments, train users to respond to alarms and keep calibration or bump-test records according to site requirements.

Common Questions

What gases should a workplace detector monitor?

Common targets include oxygen (O2), combustible gas or LEL, hydrogen sulphide (H2S), carbon monoxide (CO), carbon dioxide (CO2), ammonia, chlorine, sulphur dioxide, VOCs and site-specific process gases. The right set depends on the hazard assessment.

How often should gas detectors be calibrated?

Follow the manufacturer and site procedure. Many workplaces calibrate periodically and use bump tests before use or daily for portable instruments, especially for confined space entry or harsh environments.
