Infrared Absorption Spectrum for Methane
The dual channel receiver is a single wafer, double filtered, dual receiver with an internal optical barrier.
The elements are perfectly matched resulting in overall stability and superior performance throughout the
entire temperature range.
Using a dual channel receiver there is no need to use any special lenses or beam splitters to achieve the
different measurement bands.
The SEC MILLENIUM utilizes a unique, patented feature; the AutoAC
circuit. The AutoAC
circuit is an
automatic analog control circuit, which allows the SEC MILLENIUM to be calibrated for any combustible
hydrocarbon, provided that a calibration quality level of the gas is available. This eliminates setting
dipswitches or changing out sensors for different types of hydrocarbons, simply calibrate the unit with a
calibration gas of the specific gas to be detected.
The optics can be easily disassembled for cleaning. This does not require powering the unit down and does
not compromise the units’ explosion proof rating. The device will self-compensate for dirty optics until a
point in which the optical surfaces are completely obscured.
There are no consumable components contained in this product.
