Selection Guide (Engineering Perspective):
Identify the target gas and concentration range for your industrial application.
Determine the required alarm thresholds and sensor type (catalytic, electrochemical, or infrared).
Evaluate environmental conditions (temperature, humidity, explosion risk) to choose enclosure protection level.
Decide between portable or fixed solutions: use portable detectors for mobile inspection, temporary monitoring, and confined spaces; choose fixed detectors for continuous monitoring at critical points.
Consider OEM customization options for branding, display interface, or multi-gas integration.
