Apera Instruments LabSen 763 User manual

LabSen® 763 Blade Spear pH/Temp. Electrode
User Manual

LabSen® pH electrodes are made with proprietary sensor technologies and key components from
Switzerland. LabSen® 763 Blade Spear pH Electrode adopts a spear glass membrane with titanium blade
sheath, which can easily pierce into solid medium while protecting the sensor. This probe is designed for
pH measurement of raw/frozen meat and fish.
Features(
• LabSen® S-type spear sensor tip featured with high firmness and fast response, designed for
direct measurement of solid samples
• Built-in temperature sensor for automatic temperature compensation (ATC)
• Food-grade titanium blade sheath, easily piercing into hard samples while providing strong
protection to the sensor
• Open&Ceramic double-junction with Polymer electrolyte. No more junction clogs.
• Long life reference system improves the stability of the reference system and extends the
electrode’s service life.
• Blue gel inner solution - does not flow and will not generate air bubbles

How(to(use(
1. Insert the blue BNC connector of the electrode to the BNC socket of your pH
meter while twisting clockwise until it’s locked.
2. Insert the black RCA connector of the electrode to the RCA socket directly.
3. Before measuring, twist off the storage bottle cap (see graph on the right), pull
out the electrode and rinse it off with distilled or deionized water.
4. Perform at least a two-point calibration before measuring after connecting the
new electrode to your pH meter.
5. After using, put the electrode back into the storage bottle and twist on the
bottle cap.
Maintenance(
1. When not in use, the electrode should be soaked in the storage bottle containing 3M KCL soaking
solution to keep the glass membrane and junction in a healthy condition. Clean the bottle and replace
the soaking solution if it gets contaminated. The electrode should never be stored in pure water such
as deionized or distilled water.
2. The electrode is only as accurate as it is clean. Always thoroughly rinse off the probe before and after
each measurement with pure water in a container or with a wash bottle.
3. The transparent polymer gel electrolyte will inflate and ooze out a bit when it’s soaked in KCL solution.
This will not affect the measurement of the electrode, and it will happen more frequently with newer
electrodes. This is a “self-clean” situation especially when the junction gets contaminated. Just wipe
off the inflated gel with clean tissue and continue to use the electrode as normal.
4. When piercing meat (especially frozen meat), avoid bending the spear tip. Wash the electrode and
the titanium sheath with soap water after measurement, the titanium blade can be screwed off and
cleaned separartely if necessary.
5. The connector of the electrode should be kept clean and dry. If contaminated, please clean it with
medical cotton and absolute alcohol and blow dry to prevent the short circuit of the electrode and
slow reaction of electrode.
6. For tough contaminants, soak the electrode in Apera cleaning solution (AI1166) for 30 minutes. Then
use a soft brush to remove the contaminants. Afterwards, soak the electrode in 3M KCL soaking
solution for at least 1 hour. Rinse it off, then re-calibrate it before using again.
7. The connector of the electrode should be kept clean and dry. If contaminated, please clean it with

medical cotton and isopropyl alcohol and blow-dry it to prevent short circuit of the electrode or slow
response of the electrode.
8. The electrode should avoid testing strong acid and strong alkali solutions, as well as dehydrating
media such as absolute ethanol and concentrated sulfuric acid. If testing such solutions, the
immersion time should be minimized and the electrode should be carefully cleaned after use.
9. Every pH electrode will eventually age and fail. The typical service life of Apera pH electrodes is 12-
24 months depending on the frequency of usage and how well you keep it clean and properly stored.
We recommend replacing your electrode every 12-18 months to ensure the best accuracy.
