Series 4 Electrochemical Gas Sensors
Amphenol SGX SensorTech electrochemical sensors detect toxic gases using little to no current draw
Amphenol SGX SensorTech 20 mm diameter Series 4 electrochemical sensors can detect toxic gases such as ammonia, carbon monoxide, ethylene oxide, hydrogen, hydrogen sulfide, nitric oxide, nitrogen dioxide, and sulfur dioxide. Electrochemical sensors detect gases by producing a chemical reaction between the gas and oxygen contained in the sensor. This reaction produces a small current, which is proportional to the concentration of the present gas. The sensor is, in effect, a type of fuel cell.
Features
- Absolute gas measurement
- Wide range of gases
- Measurement ranges: ppm/ppb
- Low cost
- Little to no current draw
- Excellent response
- Great linearity
- 20 mm diameter Series 4 housing
- Long lifetime
Applications
- Underground parking garages
- Mining
- Leak detection
- Handheld detectors
- Medical ventilators
- Air quality monitoring
- Air purifiers
- Firefighter equipment
- Environmental monitoring
