Description
Gastec GSP-400FT Automatic Air Sampling Pump in the field of industrial hygiene, the accuracy of gas concentration data is directly dependent on the precision of the sampled air volume. The Gastec GSP-400FT Automatic Air Sampling Pump addresses this requirement by incorporating an integrated mass flow sensor. This technology automatically compensates for changes in resistance caused by the collection media or detector tubes, maintaining a stable flow rate throughout the entire sampling period.
The device features an intuitive dual-LCD system: the main display shows the accumulated volume, while the sub-display provides real-time monitoring of the current flow rate. Unlike manual pumps, this automatic system provides a “Constant Flow Function” which effectively eliminates sampling errors caused by temperature or pressure fluctuations. Whether you are performing short-term detector tube measurements or long-term indoor air quality (IAQ) monitoring, this pump delivers the technical reliability needed for sensitive analytical results.
