The AlphaSense CO-AF Carbon Monoxide Sensor provides an accurate and reliable way to measure up to 5,000 ppm CO by volume.

The smart board and development kit converts the sensor’s analog output current to a voltage that is measured by a high-resolution analog to digital converter. The digital voltage is corrected and compensated for temperature and pressure by a micro-controller to produce an accurate gas concentration measured in ppm (parts per million).

This can be read as RS485 serial output or can be logged in internal memory for later retrieval. In addition the board makes it easy to apply zero or span calibration.

Features

  • Excellent response time to changes in CO levels
  • Low sensitivity to temperature changes
  • Easy integration; compact & low power

    System Requirements

    • Windows XP SP2 or newer
    • Microsoft .Net 3.5 Runtime Libraries
    Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer grips sensor for easy fit and removal while maintaining a good seal.

    Micro-Pump Kit includes all the tools you need to urilize the tube-cap adapters as part of a sampling sensor system.

    Nafion tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.

    Micro gas sampling pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
