Options

Collection tube heater　GTH-1

The air sampling is used to collect samples of harmful aldehydes, by connecting the ozone scrubber to the front stage and two DNPH collection tubes to the rear stage.
However, excessive moisture due to rain may interfere with collection by causing condensation in the collection tube.
The GTH-1 prevent voltage(plus 10ºC reliable to the outside air)thus enabling reliable samoling on a 24-hour basis.
In addition, the GHT-1 has a compact and lightweight desugn so it can be attached to the GSP series.

Holder for Various Collection Tubes　GSP-SH

The collection tube is set into the holder.

GSP-SH tripod adapter　GSPSH-71

Necessary when installing the collection tube holder on a tripod.

Detector tube adapter　GSP300-13

Installed when mounting the detector tube and the collection tube on the GSP-400FT automatic gas sampling unit.

Gas sampling pump tripod stand　GSP-TRIPOD
