Combustible Gas Detector
Combustible Gas Detector measures and indicates the amount of certain gases in air using different technologies. It is employed to avoid any toxic exposure and sudden fire in different sectors for safety purposes. It is designed as portable as well as stationary units to work by signifying the levels of combustible gases with audible and visible indicators. It is well equipped with modern alarms, lights as well as a combination of signals to detect any gas leak. This multifunctional device is also capable of detecting varied gases at once in industrial plants, fumigation facilities, refineries, pharmaceutical manufacturing, paper pulp mills, aircraft, ship-building facilities, waste-water treatment facilities, etc. It is very easy to install, use and operate ensuring to provide safety to workplace and workers.
Features :
- Provides a fast and reliable output by using Electro Chemical / Pellister Sensor Technology.
- Optimized for detection of smallest leak of Oxygen, -Toxic and Combustible Gases.
- Highly resistant to poisoning and etching.
- Capable of detecting down to PPM, %LEL & %V/V.
- Digital display of Gas Concentration on LED Display
- Standard 4-20mA signal output with configurable range.
- Easy handling and programming with 3 keys for Weatherproof Models.
- Non - Intrusive programming for Flameproof model using Magnetic pen.
- Password protected programming with passwordchanging facility.
