This sensor design is easy to install, use, and maintain. The sensing element and membrane are mounted in a rugged 316SS stainless steel housing. The sensor assembly can be used in-situ with its own mounting flange, or it can be used in a flow stream with the optional 316 Stainless Steel Sample Chamber. It is less subject to contamination than other sensors because of the membrane. Also, when other oxide sensors fail, the whole sensor often needs to be replaced-a very costly procedure.
Measurements are very repeatable.
Since measurements are independent of the mass of gas, the inaccuracies and calibration problems associated with most other electrochemical sensors are eliminated. The instrument should not be used with gases which are corrosive, or which readily combine with phosphorus pentoxide to form water. Gases and materials that should be avoided include certain acids, alcohol, chlorine, fluorine, hydrogen chloride, hydrogen fluoride, amines, ammonia, alkynes, alkadienes, and alkenes .
