Declarations of Conformity

The CE mark, or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985.[1] The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.


Products for Explosive Atmospheres

The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosives.


Material Specification - Declaration of Compliance with the Order EN 10204

The material specifications show the materials of the wetted parts and the specifications they fulfill, i.e. surface quality, USP class VI tests, etc.
Please note that some products like VisiFerm DO, VisiPro DO, OxyFerm FDA and OxyGold B and G consist of a sensor body and a membrane / cap. Due to the fact that the membranes / caps can be changed the material specifications of sensor body and membrane / cap are separated. As a consequence for these products both specifications are required.
