These micro gas sampling pumps by Thomas are designed to provide a constant flow of air across any of our sample draw sensors or sensors with tube cap kits. This makes them perfect for bench-top testing of sensors for closed-loop sampling applications.

Using a pump, an air or gas sample is drawn through an optional particulate filter, water trap, and hydrophobic filter for cleaning and to remove excess moisture in the gas that might foul the sensor. The pump then pulls the sample across a gas sensor with a tube-cap that creates a sealed system. Finally, the gas is either exhausted or returned back to the original closed-loop system.
