Trouble-Shooting (Sluggish Response Time, Insufficient Sensitivity Etc.); Disposal; Warranty - Mettler Toledo InPro 3030 Betriebsanleitung

InPro 3030 pH combination electrode
3. If the electrode is stored mounted in its housing,
the same rule as described in point 2 applies, but
the storage electrolyte has to be slightly modified,
with 2 parts of buffer solution pH 9.2 to 10 parts
of electrolyte, this in order to avoid corrosion of
housing parts
4. If a electrode is stored dry for a few days by mis-
take, let it soak in the normal storage electrolyte
for several hours before use.
5. Occasionally check the connector for possible trac-
es of moisture. If necessary, clean well with de-ion-
ized water or alcohol, and afterwards dry carefully.
7 Trouble-shooting (sluggish response time,
insufficient sensitivity etc.)
The glass membrane can be reactivated using a HF
solution (order no. 51 319 053). The electrode tip
(only pH sensitive glass part) is immersed into the
HF solution for a period of about 5 minutes, is then
immediately and thoroughly rinsed with de-ionized
water and thereafter stored in buffer solution pH 4 (see
Chapter 6) up to the diaphragm for 12 hours.
Possible protein precipitation and blockage of the di-
aphragm can be treated with our special electrode
cleaner (order no. 51 340 068). However, use of the
diaphragm cleaner (order no. 51 340 070) is normal-
ly not necessary for this electrode type, as the built-in
silver-ion trap prevents the formation of silver sulfide
contamination.
Also, check the connector for possible traces of mois-
ture. If necessary, clean well using de-ionized water
or alcohol, and afterwards dry carefully.
