The Honeywell Analytics Searchpoint Optima Plus Infrared Flammable gas detector has versions for Hydrocarbon and Ethylene gases. Standard calibrations are Methane, Ethane, Propane and Butane with over 100 gas and vapour calibrations to choose. The long-life IR sensor can withstand harsh environments, is immune to chemical poisoning that can occur in catalytic sensors and is supplied with a three-year warranty.

Suitable for a range of applications from general industry through to Oil & Gas, certified for use in Zone One hazardous areas, where the potential for explosion is deemed high.

Hart models communicate by a digital connection over 4-20mA existing wiring,  providing remote access from a control room to real-time gas readings, detector status, diagnostics and configuration. Alarms can be set, event history accessed, target gas programmed, or a device named for identification. A HART enabled portable device can also be used, without having to purchase a proprietary mobile unit. The Searchpoint Optima Plus can be checked locally using the Optima Excel Local Display (OELD) smart junction box or used with the XNX transmitter.  Both of these options display readings, enable efficient maintenance resulting in less downtime.

Equipped with an integrated health check to minimise false alarms and warns of contaminated optics. Heated-optics adapt to changing environmental conditions to combat condensation.

  • Detects hydrocarbon gases including solvents
  • Fast response T50 < 3 seconds, T90 < 4 seconds (methane)
  • Operates in inert atmospheres
  • 4-20mA output and optional Hart ensures compatibility with controllers
