| Dry and oil free according to ISA-S7.0.01-1996 quality standard for instrument air. Used to flush the instrument in corrosive environement. Min. 0.2 bar - Max. 0.5 bar |
| Interferences | Strong reducing agents like hydrosulfide (S2O42–), nitrite (NO2–) > 0.2 mg/L, sulfite (SO32–) >200 mg/L and thiosulfate (S2O32–) > 5 mg/L decrease the blue color and interfere. Oxygen reacts with sulfide and must be absent. Large quantities of color and turbidity interfere. Fats, oil, proteins, surfactants and tar interfere. |
