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.
