Gas Safe Europe Ltd has been manufacturing test gases for 25 years.  First started with CO test gas (Detectagas), then came the development of smoke detection test gases (Detectasmoke). 

Unlike other test gases on the market, the GSE test gases are based on a drier composition formula, so they leave no residue in the detectors. 

All GSE products are consciously made to be user-friendly, efficient, cost-effective and ECO-friendly.  A good example is the Detectareach, if this handheld smoke detector tester with telescopic dispenser is empty through use, it can be reused again by inserting a replacement, new DSF2R aerosol test can.
