Gastec GSP-300FT-2 Automatic Air Sampling Pump

Description

Gastec GSP-300FT-2 Automatic Air Sampling Pump in the field of industrial hygiene, the accuracy of gas concentration readings depends heavily on the precision of the air volume sampled. The Gastec GSP-300FT-2 Automatic Air Sampling Pump addresses this challenge by incorporating a high-performance mass flow sensor. This sensor automatically compensates for any increase in resistance caused by the collection media, maintaining a constant flow rate throughout the sampling period.

This pump features a dual-LCD system that allows technicians to monitor the accumulated volume on the main display while simultaneously tracking the real-time flow rate on the sub-display. Unlike traditional manual pumps, the Gastec GSP-300FT-2 Automatic Air Sampling Pump provides a “Constant Flow Function” that corrects for temperature and atmospheric pressure fluctuations. This level of automation eliminates manual calculation errors and ensures that your laboratory samples or detector tube readings are based on highly accurate volumetric data.
