GSP series Air Sampling Pump

GASTEC developed a detector tube system utilising an electric suction pump in response to growing user needs for improvements in measuring time and routine in the working environment. Moreover, although the reagent filling density of detector tubes is generally high, making effective sampling with conventional electric suction pumps next to impossible at times, the compact GASTEC GSP-300FT-2 has a powerful suction performance that enables effective sampling with any of the designated detector tubes.
GASTEC's new detection tube measurement system provides performance meeting the relevant measurement criteria for the respective working environment
