Industrial Gas Detectors for Safety in the Workplace

Monitoring harmful gases in the ambient air can be challenging but crucial to ensure a safe industrial environment. Too much oxygen or toxic gas, such as hydrogen sulfide, chlorine, or ammonia, can present new dangers to employees and equipment in the area. Fortunately, finding the best sensor and monitoring system for your environment helps automate the process of gas detection and gives you peace of mind.

Industrial toxic gas and oxygen gas detectors monitor the presence of gases in a specified area and sound an alarm when they reach dangerous levels. Gas detectors are typically installed where there is a potential for a gas leak, and where unsafe gas levels pose an immediate danger to workers or equipment. Toxic gas detectors are widely used by industries including gas and oil, medical, mining, nuclear, construction, food and beverage, and industrial.
