GASERA ONE PULSE is a versatile and easy-to-use multi-gas monitoring solution offering accurate ppb-level detection at an industry-leading price. Using Gasera’s patented cantilever enhanced photoacoustic spectroscopy (CEPAS) technology, it can simultaneously measure up to 9 gases plus H₂O, and is configurable across a wide range of environmental, industrial, and occupational safety applications.
The GASERA ONE PULSE uses cantilever enhanced photoacoustic spectroscopy (CEPAS), combining a broadband IR source with narrow band-pass optical filters to achieve ppb-level trace gas detection. Unlike conventional membrane-based photoacoustic sensors, Gasera’s patented cantilever pressure sensor is over 100× more sensitive, enabling miniaturisation without sacrificing performance.
The instrument can be configured for a wide variety of applications including: SF₆ and refrigerant leak detection, anaesthetic gas monitoring, greenhouse gas emissions monitoring, soil gas analysis, occupational health and safety, photocatalysis research, animal husbandry, and fume hood performance testing.
Target gases span anesthetics (desflurane, isoflurane, sevoflurane), greenhouse gases (CF₄, C₂F₆, CO₂, N₂O), hydrocarbons (CH₄, C₂H₂, C₂H₄), inorganics (CO, NO, NO₂, NH₃, SF₆, SO₂), and VOCs (acetone, benzene, ethanol, formaldehyde, toluene, xylenes).
The optional Gasera Multipoint Sampler expands the instrument to monitor up to 12 sampling points automatically and programmably, maximising value per instrument.
