Cautions before use
A special treatment has been applied to the tip of the sensor.
Never touch it with your bare hands.
Be sure not to drop it or let it bump against the container. If the sensor is hit against a hard object or
a strong impact is applied to it, its inner part could be damaged.
If the sample contains any conductive substance other than salt, an inaccurate measurement could
result due to the effect of such substance.
Keep them away from water or solution since the sensor unit (except the part to be directly inserted
into the sample) and the main unit are not waterproof.
Otherwise, the unit may malfunction.
Notes
1. The unit can be used only to measure liquids.
The unit may display readings when used to measure solid matter, powder or gel matter, but the
readings are not necessarily correct.
When measuring, if the sensor touches any solid matter present in the sample, the measurement
values could be affected.
The readings may be unstable when the sample is flowing.
2. When there is a large temperature difference between the sample and the sensor
Measurement error may occur when there is a large temperature difference between the sample
and the sensor. To obtain accurate measurement, allow the sensor to adapt to the sample
temperature by immersing it in the sample for about 30 seconds.
The unit
is designed to measure samples between −5 to 70°C. If the temperature falls outside
this
range, "0 − L" appears and if the temperature exceeds the range, "0 − H" appears on the
display, indicating that measurement is disabled.
Avoid immersing the sensor into an extremely hot liquid.
Doing so may cause a malfunction.
3. Measuring range
The measuring range for salinity concentration is 0.1 to 10.1%. Measuring a high-salinity solution is
largely affected by the sample temperature and sensor condition.
Since precise measurement of a high-salinity solution requires special expertise and equipment,
this unit should only be used for reference purposes.
Note that if the sensor is used for measuring a high-salinity solution, which consumes much
power,
battery life is greatly shortened
