Note: The accuracy rating value is obtained from
measurements at an intermediate point of the standard solution after
two-point calibration (at room temperature and pressure).
The repeatability and accuracy rating percentages are based on the full
scale (except for salinity).
*1: Organic solvents, strong acids, and strong alkaline solvents cannot be
measured.
*2: The maximum depth for ion measurements are 100 m for nitric acid ion,
chioride ion, fluoride ion, 15 m for calcium ion, ammonia, and 3 m for
potassium ion.
*3: Based on the data measured automatically at 15 minutes intervals. The
battery life taken into account.
Periodical maintenance and calibration is necessary when a lot of
shellfishes and seaweeds exist at the measurement point.
