A gas detector pump (also called pumped type, forced air type, or sampling tube type) draws air to a handheld gas monitor through an internal (or external) tube. These pumps are typically used in confined space inspections or to get samples from a remote area for testing.

They can be used to test for carbon monoxide, hydrogen sulfide, or toxic gas. The pumped gas monitors have the ability to draw an air sample from up to 50 feet away. They operate at a 0.5 LPM or 500 cc/min with an easy USB recharge and come FACTORY-CALIBRATED. They feature a high-resolution display that indicates the temperature, time, date, and pump power readings.

The pumped gas monitoring devices are compatible with various colored tubes that reveal the presence of specific gases using color-changing reagents. The technician breaks off the ends of the tube and inserts it into a hand pump to draw a set amount of air across the inside of the reagent chamber for a specified amount of time. The results are then read on an easy-to-read calibrated scale printed on the tube.

While a pumped gas detector can make performing certain tasks much easier and safer, it is important to keep in mind that a pumped detector will not detect hazardous gases any faster than a non-pumped detector. It will still depend on the specific application and governing regulations or standards to determine whether it is safe to enter a confined space or not.
