The CO-A1 AlphaSense 5,000ppm Carbon Monoxide sensor is designed to detect highly dangerous toxic gas that poses a significant threat to those working in its presence. The circuit board's microprocessor provides zero and span calibration as well as barometric pressure, temperature and % relative humidity sensors. Features on-board memory to log data when used in a remote device.
This sensor can also integrate within various applications such as fixed systems to monitor indoor air environments and industrial safety applications.

Accessories
easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must .
. Custom USB cable enables RS485 communication to GasLab Software for EC Sensor Board and Development Kit.
includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
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.
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.
gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.
