CO-AF Alphasense 5,000ppm 20mm Carbon Monoxide Smart EC Sensor

The CO-AF AlphaSense Carbon Monoxide sensor is designed to provide accurate and reliable measurement up to 5,000ppm CO by volume in homes, offices, and industrial applications.

Note: Once an electrochemical (EC) sensor is purchased from CO2Meter.com and the sealed packaging is opened or the sensor module is installed, it is no longer eligible for return due to the limited operational lifespan that begins upon activation.

**Please Note: MOQ 10pcs - 2-4 week lead time**

Features

Electrochemical Sensor Measures up to 5,000ppm Carbon Monoxide
Barometric Pressure, Temperature and % Relative Humidity Sensors
Serial UART output and RS485 output with optional RS485 cable
Easy Integration; Compact & Low Power

Models

CO-AF Sensor Only – for integration into high-volume OEM products, 20mm diameter, the industry standard size for portable gas detectors.

Free Easy-to-use GasLab® Software

The Smart EC Board uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.

System Requirements

Windows XP SP2 or newer
Microsoft .Net 3.5 Runtime Libraries

Accessories

Tube Cap Adapters 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 mount the tube cap permanently.

RS485 Cable. Custom USB cable enables RS485 communication to GasLab Software for EC Sensor Board and Development Kit.

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.

Probe Enclosure for Development Kits gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.
