Kofloc Flowmeter With Precision Needle Valve Model RK1250 Series
GSP series Air Sampling Pump GSP-300FT-2
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
Features
•Flow volume of 50-250mL/min can be set for the inserted detector tube
•The fixed flow function automatically regulates load changes
•Real-time flow volume and integrated flow volume are automatically corrected to the values for 20ºC
•Automatic start enables sampling to begin after a preset time
•Automatic stop at preset time/volume, with total flow and transpired time calculations
•Ventilation system configured for uninterrupted sampling
•Compact and lightweight; 10 hrs. continuous operation on 2 AA batteries
•Specially-suited detector tubes for continuous workplace sampling (10 min.)
•Formaldehyde tubes 91P, 91PL can be used
•Activated carbon and other solid-collecting detector tubes can be utilised
