Description
■ Caution
Calibration solutions are sold separately. For accurate measurement it is recommended to use calibration solutions.
■ Notice
- The sensor may be damaged to shorten its life if it is used for liquids such as organic solvents, oils, adhesives, surface-active agents, strong acids (pH 0 to 2), or strong alkalis (pH 12 to 14).
- The reading may become unstable if you measure pure or tap water.
- If you measure food or drink, take a sufficient quantity of a sample in a separate container so that the end of the sensor is immersed at least 3 cm in the sample. Do not eat or drink the sample after measurement.
- The sensor is made of glass, so take a great care in handling. Be careful not to injure yourself when it is broken.
