Gas Detection Sensors:

318 Products Found

Farnell offers a wide range of gas sensing technologies, including Electrochemical sensors, Pellistor gas sensors, Infrared gas sensors, Photoionization Detectors (PIDs), MEMS gas sensors, and photoacoustic gas sensors. A specific gas technology can be chosen only after multiple factors are considered, such as the type of gas under detection, whether the device is portable or fixed, single or composite, diffusion or pumping, and the specific detection principles involved.

Environmental gas sensors enable the detection and monitoring of various gases in the environment for total assurance of safety, efficiency, and compliance in several industries. They alert about hazardous gases by triggering visual and audible alarms at home or in industrial environments, thus keeping the residents, employees, and the organization safe. It is, therefore, crucial to choose the correct gas-sensing technology depending on its operating principles, applications, and their respective advantages and disadvantages. It is also essential to know how to calibrate a gas sensor. 

Farnell’s selection features portable gas detectors, fixed gas sensors, and multi-gas detection designed to provide real-time and precise measurements of gases such as carbon monoxide (CO), methane (CH4), hydrogen (H2), ammonia (NH3), and many others.
