Cautions on use
Safety Precautions
Points of concern
The materials used of the electrode may dissolve in the
sample depending on the specified sample or lengthy
measurement. Do not eat the whole, or the part around
where the electrode sensor touched, of measured
samples.
If measured sample gets on the skin, wash off it com-
pletely with soap and water.
Do not touch the sensing part and sensor terminal, or It
may be damaged by static electricity.
Store the product in dry conditions. Storage area should
be kept away from high temperature, high humidity, and
direct sunlight.
Do not wet the electrode connector and the sensor ter-
minal.
Avoid continuous use in high temperature, acids or alkali
sample of 0.01 mol/L or thicker. Failure to comply may
cause decline life period of the sensor.
White powder or solution may be generated at the liquid
junction. This is leaked internal solution of the reference
electrode, and not a symptom of trouble. Rinse the
sensor with ion-exchange water before use.
If internal solution of the reference electrode gets on the
skin, wash off it completely. In case that the solution gets
into the eyes, continue to flush the eyes with running
water. And after washing the eyes thoroughly, get
medical help immediately.

CAUTION
Handle carefully the sharp electrode tip to not get hurt.
If calibration standard solution gets on the skin, wash off it
completely. In case that the solution gets into the eyes, continue to
flush the eyes with running water for at least 15 minutes. And after
washing the eyes thoroughly, get medical help immediately.

Assembling sensor and converter
Note
Do not touch the sensing part and sensor terminal, or It may
be damaged by static electricity.
When tightening the nut, no gap should be left between the
nut and the sensor. If the nut is not tightened enough, water
may enter the inside of the sensor and the sensor may be
damaged.
1. Remove the end cap from the sensor, and the seal from
the liquid junction. Make sure that the O-ring is attached
to the sensor.
2. Turn the nut to the left to remove it from the converter.
3. Insert the sensor to the converter slowly checking that
the O-ring is untwisted, and match the

marks on the
sensor and converter. Then turn the nut to the right to fix
the sensor.
