The H2S-A1 AlphaSense Hydrogen Sulfide Sensor (formerly known as the AP-0006) is designed to detect low levels of hydrogen sulfide in ambient air using well-known fuel cell technology.

This 20mm diameter sensor is the industry standard size for portable gas detectors and also is compatible with the EC board.

For Sensor Tube Caps, please look under the "Accessories" Tab

With very high sensitivity and low zero, accurate and stable readings are possible when measuring current concentration ranges at the parts per million level.

  • 0 to 100ppm H2S sensor
  • Does not require calibration
  • Up to 2 year lifespan
  • Small, compact and maintenance free

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 utilize 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.

Sensor Pin Sockets - Manufacturers do not recommend soldering to the pins. Pin sockets can be purchased from Andon distributors. Click here to search for your sensor's socket. Select the brand PDF, find your sensor, then search for the Andon part number for your sensor's socket.
