Important

In order to have accurate and stable measurements, it is important that the

membrane surface is in perfect condition. This semipermeable membrane

isolates the sensor elements from the environment but allows oxygen to enter.

If any dirt is observed on the membrane, rinse carefully with distilled or

deionized water. If any imperfections still exist, or any damage is evident (such

as wrinkles or tears-holes), the membrane should be replaced.

Make sure that the O-Ring sits properly in the membrane cap.
