GSP series automatic gas sampler
Model: GSP-250FT
Features
- Integrated electronic flowmetre enables real-time flowrate values to be digitally displayed
- Constant flow rate function automatically controls changes in flow rate caused by variations in load
- Automatic shut-off of air pump by preset timer; digital display of integrated flow rate
- Automatic shut-off of air pump at preset volume; digital display of elapsed time
- Displays instantaneous and integrated flow rate as well as elapsed time during air pump operation as set for both the timer and constant volume modes
- Automatic calibration of instantaneous and integrated flow rates to appropriate values at 20ºC
- 24-hour continuous fixed volume sampling (equipped with Ni-Cad cell, no external AC power source required)
- Employs a quiet air pump
- One-touch switching from timer to fixed parameter mode
- Compact and light (tripod-mounting possible)

The air sampler collects aldehydes which are hazardous air pollutants. The ozone scrubber is connected to the front stage and two DNPH collection tubes to the rear for air sampling. However, excessive moisture due to rain may interfere with collection by causing condensation in the collection tube. The GTH-1 prevents condensation by heating the collection tube to a temperature higher than the dew point with a direct current voltage (10ºC to 15ºC higher than the ambient air temperature) thus enabling reliable sampling on a 24-hour basis.
