Type ***1 Combined
Electrode
Usage:
This electrode consists of a
sensitive glass electrode combined with a silver/silver chloride
electrode. It can be used to measure pH value of an aqueous
solution without other reference electrodes. Its measuring range:
pH 0 to *4, suitable temperature: 5 to *0℃, pH
value of cell zero-point: 7±0.3pH.
Operation and
maintenance:
â‘´ whenever a new electrode is used for the first
time or used once again after laying for a long time, soak the
glass bulb in distilled water for about 8 hrs.
⑵ when
measuring, pull out the rubber stopper situated on the upper part
of the electrode, take off the rubber cap, cover the electrode
with a protective casing of polyethylene so as the small hole on
the casing and the micro-hole of ceramic core on the glass tube
are in alignment.
⑶Immerse the protective casing in distilled
water wholly for cleaning before measurement. Both the electrode
bulb and micro-hole should be immersed simultaneously in solution
to be measured during measurement. When another solution will be
measured, rinse the protective casing thoroughly with distilled
water first to avoid impurity being brought into solution.
â‘· The
internal filling solution of the reference electrode is a 3.3N
solution of KCl and saturated with AgCl. This solution should be
maintained over half a tube and may be filled up from the upper
orifice, which must be covered with the rubber stopper when not
in use.
⑸ when
it is used together with a pH meter, the pH value of cell
zero-point must be lain within the adjustable range of pH
meter.
⑹ No
contamination on the glass bulb, if there is some, wipe it clean
by acetone, then soaked in distilled water for 8 hrs before
using.
⑺ It
cannot be used in non-aqueous solution and dehydrating
agent.
â‘» The
insulated part of plug should be kept clean and dry.
