SnO2 surface functionalization was performed in order to obtain sensitive and selective ammonia gas sensor that operates at room temperature. The first step of functionalization is the covalently attachment of 3-aminopropyltriethoxysilane (APTES) film on SnO2 in vapor or liquid phases. The characterization performed by the Infrared Spectroscopy and X-ray Photoelectron Spectroscopy, show that ...

Ammonia gas is widely used in manufacturing processes, but high concentrations pose serious health risks to workers. RC Systems provides ammonia sensors and detectors for reliable monitoring of NH3 gas and other toxic substances.
Ammonia Gas Sensor . Designed to detect ammonia levels ranging from 1ppm (30 times below the point at which ammonia can be smelled) to 5+ ppm, this sensor will consistently provide the protection needed to ensure a safe, ammonia-free environment. It is constructed with a state-of-the-art, colored membrane, which changes from a canary-yellow to a deep-blue color in the presence of ammonia ...
The gas detection units can detect a wide range of refrigerant gases including Ammonia (R717), CO2 (R744), fluorinated refrigerants (HCFC and HFCs), and Propane (R290). They come with various sensor technologies to match the specific refrigerant, application, and safety requirements of the refrigeration system including electrochemical (EC), semiconductor (SC), Pellistor (P), and infrared sensors.
07/02/2017· GAS sensor technology is a fast meat freshness detection method. Meat is composed of water, protein, fat, and some carbohydrates; enzymes and bacteria will decompose the meat into volatile gases [].The protein will decompose into ammonia, hydrogen sulfide and ethanethiol.
While Ammonia’s distinctive smell makes it relatively easy to initially identify, accurate calibration is needed to ensure life safety. Therefore, real-time monitors are necessary to allow continuous determination of the Personal Protective Equipment (PPE) necessary to provide proper protection from ammonia. ammonia detector ammonia monitor ammonia gas detectors
