Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors and add the ability to measure barometric pressure, temperature and % relative humidity from the gas sample. Molded polymer grips sensor for easy fit and removal while maintaining a good seal.
RS485 Modbus RTU Cable Custom USB cable enables RS485 Modbus RTU communication to GasLab Software for MX Sensor Board and Development Kit.
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.
