Gas Detection Sensors

Industrial Gas Monitoring Instruments from Agro Enviro Tests

Gas Detection Sensors supplied by Agro Enviro Tests are electronic measurement devices designed to detect and quantify specific gases or groups of gases present in agricultural environments. These instruments convert chemical interactions into electrical signals that represent gas concentration levels expressed in parts per million or percentage by volume.

Typical sensor categories include:

Electrochemical Gas Sensors

Electrochemical detectors measure target gases through oxidation or reduction reactions at an electrode surface. Current output is proportional to gas concentration and is commonly used for ammonia, hydrogen sulfide, sulfur dioxide, and nitrogen oxides monitoring.

Infrared Gas Detection Sensors

Non-dispersive infrared sensors measure gases such as carbon dioxide and methane by analyzing infrared light absorption at specific wavelengths. These detectors provide stable long-term measurement with minimal cross-sensitivity.

Catalytic Combustible Gas Sensors

Catalytic bead sensors measure flammable gases by detecting heat generated during catalytic oxidation. These sensors are frequently used for methane and volatile organic compound monitoring in manure and storage facilities.

Semiconductor Gas Sensors

Metal oxide semiconductor detectors measure gas concentration through changes in electrical resistance caused by gas adsorption. These sensors are suitable for multi-gas screening and early detection applications.

Agro Enviro Tests supports system integrators and engineering teams by supplying sensors designed for integration with agricultural IoT controllers, data loggers, and supervisory monitoring platforms.

Functional Capabilities for Agricultural Atmospheric Monitoring

Gas Detection Sensors are engineered to operate in demanding agricultural conditions where humidity, dust, and temperature variations affect measurement stability. Sensor electronics include signal conditioning, temperature compensation, and long-term drift correction algorithms.

Measurement capabilities typically include:

• Continuous monitoring of ammonia concentrations in livestock housing and manure handling areas
• Carbon dioxide monitoring for controlled growing environments and soil respiration analysis
• Methane detection near anaerobic digesters and manure storage systems
• Oxygen monitoring in controlled atmosphere storage and confined work areas
• Hydrogen sulfide monitoring in waste processing facilities and slurry storage areas
• Volatile organic compound measurement in pesticide storage and processing zones
• Multi-gas monitoring through modular sensor arrays connected to a single controller
• Alarm outputs for high and low concentration thresholds
• Data logging with timestamped measurement records
• Integration with telemetry networks and industrial monitoring systems

Field deployments across North America have demonstrated that continuous gas monitoring improves ventilation management and reduces the likelihood of hazardous exposure conditions.
