CH-A3 Alphasense 2.5% Pellistor Gas Sensor
Couldn't load pickup availability
The CH-A3 Alphasense Pellistor Gas Sensor (formerly known as AP-0012) detects low levels of flammable hydrocarbon gases including methane, ethane, propane, butane, acetylene, ethylene and isobutylene in ambient air.
This 20mm diameter sensor is the industry standard size for portable gas detectors. All pellistors are housed in certified flameproof chambers.

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.
Sensor Pin Sockets - Manufacturers do not recommend soldering to the pins. Pin sockets can be purchased from Andon distributors. Click here to see the PDF of all AlphaSense sensors pin sockets, find your sensor brand, then find and search for the Andon part number for your sensor.
