I. SPECIFICATIONS Model: MILLENIUM Infrared Hydrocarbon Gas Detector Available gases: Methane Hexane Isobutane Ethane Octane Ethanol Ethylene Benzene Methanol Ethylene Oxide Ethyl Benzene 1-Butene Propane Toluene Cyclohexanone Propylene Xylene Cyclohexanol n-Butane Heptane DimethylPropane Please note that this list is not all-inclusive. The MILLENIUM can be calibrated for most hydrocarbons, provided a calibration gas is available. -
Page 5: General Description
II GENERAL DESCRIPTION CONVENTIONS The following conventions are used in this manual. Warning Statement VDC (DC Voltage) MILLENIUM The MILLENIUM Infrared gas detector is a microprocessor based intelligent gas detector that continuously monitors combustible hydrocarbon gases and vapors within the Lower Flammable Limit (LFL). The MILLENIUM is ideally suited for use in harsh environments and where the cost of required maintenance for conventional catalytic detectors is prohibitive. - Page 6 Infrared Absorption Spectrum for Methane 100% Reference Absorption Band Band Wavelength 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.

III. OPERATION Installation and Startup Warning: The user shall be made aware that if the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. The first step in the installation process is to establish a mounting location for the MILLENIUM. Select a location that is typical of the atmosphere to be monitored or close to the anticipated source of a dangerous gas. - Page 8 Warm-up When power is applied to the detector, it enters a one (1) minute warm-up mode. The output current will be 0.8 mA during the warm up time period. At the end of the warm-up period with no faults present, the detector automatically enters the normal operating mode (4 mA).

IV. CALIBRATION SEC MILLENIUM The MILLENIUM is factory calibrated zeroed and spanned. Unlike catalytic sensors it does not require routine span gas calibration to ensure proper operation. The MILLENIUM can be calibrated for almost any hydrocarbon using a calibration gas of the hydrocarbon that is to be detected (target gas). -
