Call 800.959.0299 to speak with a sales representative or visit us on the web at www.analyticaltechnology.com High Level Ammonia Gas Detector The Model E12-15 IR Infrared Gas Detector is a rugged reliable microprocessor based intelligent gas detector. The E12-15 IR can be used to monitor from PPM levels to explosive levels of ammonia gas. The E12-15 IR is ideally suited for use in harsh environments where electrochemical sensor life can be short. Areas such as engine rooms, emergency vents, or other high level NH3 areas are excellent appliations. The E12-15 IR Infrared Gas Detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology. The E12-15 IR is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to full scale. • Requires no routine calibration to ensure proper operation • Continuous self-test automatically indicates a fault, with fail to safe operation • A multi-layered filtering system protects optics from dirt and water ingress • Straight optical path eliminates the need for reflective surfaces, such as mirrors or beam splitters • Highly resistant to poisoning and etching • Standard 4 to 20 mA output (current source) • Explosion proof housing designed for harsh e

INFRARED DETECTION TECHNOLOGY Detection Method The Model E12-15 IR Infrared Gas Detector uses infrared absorption technology for detecting ammonia gas. Gases absorb infrared light only at certain wavelengths. The concentration of a gas can be quantified by measuring and comparing intensities in light bands where there is significant absorption by the target gas in bands where there is little absorption by the target gas. The Model E12-15 IR uses an infrared light source that passes collimated light through a waveguide containing the gas sample. At the other end of the waveguide is a...
