The Searchpoint Optima Plus is a point infrared hydrocarbon gas detector certified for use in potentially explosive gas atmospheres. The device's infrared detection principle provides the fastest response speed and fail-safe reliable operation, thus ensuring that your plant is safe, protecting your personal safety and maximizing your safe production time and reducing the need for routine maintenance. Requires less operating expense than traditional catalytic combustiongas detectors. Advanced internal fault diagnosis and false alarm immunity design ensure that the Searchpoint Optima Plus provides the highest level of operational integrity.
Searchpoint Optima Plus is widely proven to be a market-leading high-performance, high-sensitivity hydrocarbon flammable gas spot infrared detector.
With more than 40 years of experience in the design, manufacture, installation and maintenance of point infrared gas detectors, Honeywell Analytics has successfully used more than 100,000 point infrared hydrocarbon gas detectors worldwide in a wide range of fields – from light industry to the most demanding offshore oil platforms.
Typical applications for the Searchpoint Optima Plus include environments where catalytic combustion beads may be poisoned or inhibited by substances or environments that require extensive maintenance for commonly used flammable gas detectors, such as: offshore oil and gas platforms, offshore production storage and offloading platforms (FPSOs), tankers, onshore oil and gas platforms, refineries, LNG/LPG tanking plants, Pressure metering stations, gas turbine power stations, solvent printing and coating processes.
