GASTEC - portable unheated Hydrocarbons FID analyser

Runtime of more than 60 hours with a Hydrogen refill for longer analysis projects

More than 5,500 units sold worldwide

The GASTEC portable FID analyser is a VOC (Volatile Organic Compounds) analyser that runs according to the principle of flame ionisation. This technique, used for many years by stand-alone analysers (see our type 201 analyser), overcomes any disparities that may exist between the different compounds measured.

The portable GASTEC FID analyser gives an almost linear response between the different organic molecules (alcohols, ketones, aromatics, alkanes, VOC ...).

The portable GASTEC FID analyser, with its reliability and rapid response, is of exceptional quality, and is able to detect leaks in under 2 seconds.

GAS-TEC - Compounds detected
The portable GASTEC FID analyser analyses VOCs (Volatile Organic Compounds).

GAS-TEC - Scale of analysis
Large scale of measurement <1 ppm to 10,000 ppm (100,000 ppm also possible).

GAS-TEC – Hydrogen cylinder refill station
The refill station is completely stand-lone. Filling is done from a parent bottle.
