Ch. 10. Environmental Scanner Overview Sec. 10.4. Chemical Compatibility
10.4. Chemical Compatibility
The ES scanner is equipped with FKM (Viton equivalent) O-rings in the factory. For cases where viton
is chemically attacked, please switch to the included FFKM (Kalrez equivalent) O-ring. These rings can
be found in a small box, shown in
10.2. When you no longer require these O-rings, please store them
back in the case. FFKM Costs between 10 and 100 times more than FKM, so do not misplace them.
