Semi Disposable Glass Fiber Optic Sensors

SELECT OPTION:

Low cost glass fiber optic oxygen sensors, zero long term drift, borosillicate core/clad, NA 0.55. Custom lengths available (minimum order 10).

There are two types of cap coatings

1) The AP series designed for zero long term drift with applications:

  • Environmental monitoring
  • Process control
  • In line monitoring in beverage industry
  • Waste water treatment
  • Long-term measurement in soil

2) the HCR series for Hydrocarbon Resistant Oxygen applications:

  • Oil industry: refineries, fuel processing
  • Chemical industry involving explosive hydrocarbons and flammable solvents
  • Aviation industry: OBIGS, OBOGS, online real-time fuel tank monitoring​
