Description
The TX Carbon Dioxide (CO2) Industrial Sensors are designed for industrial applications where RS485 Modbus RTU or 4-20mA outputs and 6-24VDC is required.
The TX Sensor Smart Boards combine the GSS ExplorIR®-M 5%, 20% or 100% carbon dioxide sensors with a PCB that provides RS485 or 4-20mA output options and 6-24VDC power options on a 30mm PCB for industrial applications.

Software
Free Easy-to-use GasLab® Software
The Devkit uses GasLab® software for setup, calibration, data logging, and real-time data analysis via USB. 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.
- TC-1 – 3 mm side mounted ports
- TC-2 – 3 mm top mounted ports
- TC-3 – 4.5 mm top mounted ports
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.
