AQ+7SO2 Sulphur Dioxide SO2 Gas Sensors 4th Electrode Use In Environment Air Quality
AQ+7SO2 Sulphur Dioxide SO2 Gas Sensors 4th Electrode Use In Environment Air Quality
Key Features: Air Quality Specifications, PPB
Common Applications: Air Quality
Detailed Description:
The AQ+7SO2 sulfur dioxide sensor is a 7-series specification with a 4-pin interface. The AQ+7SO2 requires a 0V bias voltage. The AQ+7SO2 has a measurement range of 0 - 20 ppm, an output current of 400 ± 100 nAppm, a response time of less than 60 seconds, and a warranty of 24 months. Key features of the AQ+7SO2 include: high accuracy, strong environmental stability, and excellent price/performance ratio.
Key Features: 4th electrode for improved baseline v temperature performance
