MAINTAINING
6.1
Probe maintaining
1.
pH probe may not dry storage
，
soak in with 3.0mol/L KCL solution box
；
2.
Suggesting according to the measurement media condition clean the probe timely
，
calibrate
the probe after mating the meter..
3.
If probe is slicked by
suspended matter
，
can use 0.01mol/L HCl or NaOH solution to clean
，
then use clear water washing up.
4.
If the instrument still can not finish the calibration after above method
，
means the probe can
not use, should change new one
；
5.
ORP probe p
latinum ring surface is bright normally
，
surface
suspended matter will influence
the measurement
，
may use 0.01mol/L HClor NaOH solution cleaning
，
then use clear water
washing up.
6.
Strong oxidation or reduction causing rough surface will effect probe’s response potential
，
may use toothpaste lighting the platinum surface
，
then use clear water washing up.
7.
washing cleaned probe suggested immerse into 3.0mol/L KCL solution hydration 6 hours
then use it;
8.
When calibrate pH probe and instrument, the buffer solution must processing under 25 .
℃
6.2 Probe using attention
1.
pH/ORP probe is consumption type probe, it will ineffective after long time storage, so
suggested to buy to use
，
do not storage
；
2.
Prohibit sensitive glass-film
（
glass boll steep
）
working in hydrofluoric acid, fluorinion and
high concentration sulfion environment.
3.
Prohibit using standard configuration pH/ORP probe measure the organic solution which
can soluable PC and ABS
（
such as CCL4
、
CHCLCCL2
、
C4H8O
），
or it will damage the
probe shell
；
4.
Using cotton swab and neutral warm cleanser clean the ball sleep and surface of b
ounds on
liquid
，
do not use acid or causticity such strong solution or abrasive material.
5.
Biopharmaceutical
、
high pressure sterilization recommend using high temp. glass pH probe
and matting forcing sheath.
6.
pH signal belong to weak current signal
，
the cable should independent
，
prohibit wiring with
strong current.
