In general, when placing gas sensors, you should consider the following principles:
DO
- Place sensors close to the possible gas/leak source.
- Place sensors in areas where air currents are likely to produce the highest gas concentration, including areas where gas buildup is likely, such as corners or stopping points of gas-releasing moving devices.
- Factor in the monitored gas’s vapor density when compared to air. Sensors should be located near the floor for gases or vapors three or four times heavier than air. They should be installed near the ceiling or roof to detect lighter-than-air gases.
DON’T
- Don’t place sensors near entrances or fresh air vents during representative room sampling, as sample concentrations will be diluted by incoming air.
- Don’t mount the detector on a surface subject to vibration as it could damage the detector. Best practice is to anchor the detector to a wall or firm base rather than to a motor housing.
