Sensorex 8000 Series Product Instruction Sheet

8000 Series pH/ORP Electrode Platform
Product Instructions
Introduction
Congratulations on your purchase of your Sensorex S8000
series electrode platform. The platform is designed in a modu-
lar fashion with the flexibility to use only the parts needed, or
to add or modify installation and interface requirements with
little or minimal cost impact. All mounting adapters and cables
are designed to be reuseable. Replace only the electrode car-
tridge as needed.
Electrode Care and Use Tips
1. The S8000 pH and ORP electrodes are shipped with a cap
containing a solution of pH 4 buffer and potassium chloride.
The cap should remain on the electrode until it is used. If the
electrode is used infrequently the cap and its solution should
be saved and the electrode stored in it. Store pH and ORP
electrodes in pH 4 buffer if soaking solution is discarded.
Before using the pH electrode remove the tape around the
top of the black cap then slide the black cap off of the
electrode. Next, remove small o-ring under black cap and keep
with black cap or discard (SEE FIG 1A).
2. Electrodes are a form of battery and have limited shelf lives.
Electrodes in inventory should be rotated so that the older
electrodes are used first. The date code is stamped on each
electrode by fiscal week and year (Example: 4608 = week 2 of
November 2008). See FIG 2.
3. After exposure to a sample, buffer or rinse solution, carryover
can be minimized by blotting—never by wiping—the elec-
trode with a clean non-abrasive paper or a clean cloth towel.
Do not use a brush on pH glass.
4. As a rinse solution, measure and use a portion of the next
sample or buffer. This action will minimize carryover
contamination.
5. When calibrating pH electrodes, use a buffer close in value to
that expected from the sample for one-point calibrations or as
the second buffer for two-point calibrations (See below). This
action will minimize span errors. ORP electrodes are typically
not calibrated. However, a solution to verify electrode perfor-
mance should be used periodically. 225mV solution, Zobell's
solution (Part no. B225), is a good choice for single point
verification.
