Photoacoustic Gas Monitor INNOVA 1412
The LumaSense Photoacoustic Field Gas-Monitor INNOVA 1412 is a highly accurate, reliable and stable quantitative field gas monitor. Its measurement principle is based on the photoacoustic infrared detection method. This means that the 1412 can measure almost any field gas that absorbs infrared light.
Appropriate optical filters (up to 5 + water vapor) are installed in the Field Gas Monitor INNOVA 1412's filter carousel so that it can selectively measure the concentration of up to 5 component gases and water vapor in any air sample. Further, Field Gas Monitor INNOVA 1412 can compensate for interference between the measured field gases, using the unique Cross-compensation feature. The INNOVA 1412's detection limit is field gas-dependent but typically in the 10-² ppm region.
Field Gas Monitor INNOVA 1412 Uses
- Quantitative analysis of up to 5 components and water vapor in gas mixtures
- Indoor air-quality and ventilation measurements
- Ventilation measurements using tracer-gas
- Occupational health and safety measurements - of possible production or accumulation of toxic/carcinogenic substances in working areas
- Monitoring of anaesthetic gases in hospitals
- Emission monitoring of exhaust from chemical processes
INNOVA Gas Detection Limits
The optical filters used in Field Gas Monitor INNOVA 1412 display different characteristics while sharing a basic design. Each filter comprises three separate infrared elements; a narrow-band pass element, a short-wave pass element and a wide-band pass element. The narrow-band pass element has very specific transmission characteristics defined by the short-wave pass and wide-band pass elements, which prevents transmission of light at other wavelengths.
