  • With over 40 years experience in the design, manufacture, installation and maintenance of point infrared gas detection, Honeywell Analytics currently has a worldwide installed base of over 100,000 infrared point hydrocarbon gas detectors in a wide spectrum of applications from light industrial to the most demanding of offshore environments.

    The Honeywell Searchpoint Optima Plus is an infrared point Hydrocarbon gas detector certified for use in potentially explosive atmospheres. The unit’s infrared detection principle offers the fastest speed of response and fail-to-safe operation, ensuring that your plant is compliant, your personnel are protected and your production process can deliver maximum up-time.

    Significantly reduced routine maintenance, when compared with other IR sensor designs as well as conventional electro-catalytic based gas detectors, provides the lowest cost of ownership available during the usable life of the instrument. The development of advanced internal fault diagnostics and false alarm rejection algorithms ensures that the Honeywell Analytics Searchpoint Optima Plus Infrared Point Hydrocarbon Gas Detector delivers the highest level of operational optimization and detection accuracy.

    Superior Technology, Unmatched Accuracy – Dual sensors, dual filtered sources is unique to the Optima Plus. This dual scheme with FILTERED SOURCES fully compensates for changes in both source and sensor performance caused by the known degradation that occurs on all manufactures infrared technology components AND this technology increases overall detector accuracy, especially in the most challenging conditions that have proven to disable other IR sensor design schemes.
