Disposal instruction:
The device must not be disposed in the unsorted municipal waste! Send the device directly to us (sufficiently stamped), if it
should be disposed. We will dispose the device appropriate and environmentally sound.
Points to be observed during operation
a.) In case of low battery voltage "BAT" is displayed; make sure to exchange battery immediately as too low an operation
voltage may lead to incorrect measuring results.
We recommend to take out battery if device will not be operated for some time or storaged over 50°C.
Please note: If the battery voltage falls even lower the voltage may not be sufficient for "BAT" to be displayed so that
there will be no "BAT" indication although the battery has been used up.
We recommend to make it a rule to always check the battery if the values indicated seem to be
completely out of range.
b.) Make sure to maintain device an electrode properly and to operate it in accordance with the specification listed (do not throw,
knock etc.).
c.) The electrode must be stored in 3 mol/l KCl (ours type: KCl3M), in order to avoid drying out (excluded GE103).
d.) Before measuring the protection-cap has to be removed.
e.) Our pH-electrodes can be used in a degree range from 90° to ±45° compared to horizontal
