Searchpoint Optima Plus

The Honeywell Searchpoint Optima Plus is a hazardous area certified flammable infrared gas detector. Infrared gas detectors are ideal for applications in the harshest environments or where catalytic poisons may be routinely present. Searchpoint Optima Plus has the fastest speed of response combined with the highest reliability and reduced routine maintenance. Two versions are available: a hydrocarbon unit and an ethylene unit that can detect a wide range of hydrocarbon gases including solvents.
