Combustible gases absorb infrared radiation at certain characteristic wavelengths. A typical non-dispersive infrared (NDIR) detector passes a source of infrared energy through the sample and measures the energy received by one of two detectors. The active detector responds to wavelengths in the same band as the sample gas, while the other detector measures a reference to compensate for changes within the instrument.
When selecting a flammability analyzer, it’s always a good idea to enlist the advice of a specialist in the field. Do not assume that the analyzer which was correct for a previous job will also be the right choice for another application. Whether new or similar, the specific details of each application need to be examined closely to prevent disaster.
Baking and drying ovens have been workhorses in the food, textile, and paper industries for many decades – and many oven users have clung to decades-old equipment because profit margins can be low in their industry. Although many of these older ovens still function with roughly the same level of consistency, certain newer technologies can result in reduced operating costs and lower risks to production and personnel due to fewer shutdowns.
