Spare parts
The measurement station is constructed using a number of individual instruments. An
itemised parts list is made for each measurement station and placed in the device ring
binder. This means that the user can quickly identify individual items.
The parts list can be found in section 3 in the ring binder.
However, it is recommended that the user holds the most important consumables and
parts subject to wear and tear on stock (see maintenance plan in section 10 in the ring
binder). In order to make the correct decission the storage time and conditions must be
considered, e.g. pH sensors etc.
