Gas Detection Q&A - For Your Safety Environments

Built-in advanced gas detector sensor and sound & light alarm to ensure precise and safe gas detection in hazardous applications.

Q: Where is the best place to install a fixed gas detector?

A: The ideal location for installing a fixed gas detector depends on factors such as potential gas sources, airflow patterns, and gas properties. Generally, it's best to place the gas detector near potential gas leak sources, but not too close to avoid false alarms from minor fluctuations. Install at a height appropriate for the gas being detected; lighter-than-air gases should be detected at higher levels, and heavier-than-air gases at lower levels. Avoid extreme environmental conditions, such as high humidity or corrosive substances.
