 Points of concern

 Do not give an excessive shock to the sensor cartridge.
 Cracked or chapped sensor cartridge can not be used.

Replace such sensor cartridge with a new one.

 Avoid continuous measurement soaking in the strong

acidic or alkaline solution concentrated more than 0.01
mol/L. These solution may reduce the performance and
the lifetime of the

sensor cartridge.

 Do not to use the sensor cartridge in a solution in which

hydrofluoric acid

(HF) is contained. Glassware will

corrode in the HF solution.

 Avoid sudden temperature change over 50 °C on the

sensor cartridge. The
the glassware might be cracked.

 Solid particles of silver chloride might be observed

sensor body might be deformed or

floating in the inner solution of the responsive glass
membrane. This is not a problem and this will not affect
performances of the

sensor cartridge.
