How to use conductivity meter properly

Conductivity meters are instruments used to measure various liquid media. They are mainly used to measure the conductivity value of liquid media. When equipped with electrodes with corresponding constants, they can accurately measure the conductivity of high-purity water. Common types include portable conductivity meters and desktop conductivity meters.

How to use conductivity meter properly

1. In order to ensure measurement accuracy, the electrode should be rinsed twice with distilled water or ionized water less than 0.5μS/cm before use, and then rinsed three times with the test sample before starting the measurement.

2. Before and after use, avoid moisture on the plug, otherwise unnecessary measurement errors will occur.

3. The measuring electrode is a precision component, do not disassemble or decompose it, do not change its shape and size,do not clean it with strong acid or alkali to avoid inaccurate measurement results due to changes in the electrode constant.

4. When the equipment is not in use, put it in a ventilated and dry environment to avoid leakage or measurement errors caused by water droplet splashing or moisture.

5. When measuring the conductivity of pure water or ultrapure water, in order to avoid drift of the measured value, it is recommended to use a sealing groove and measure the flow in the sealed state. If a beaker is used for sampling and measurement, a relatively large error may occur.

6. The equipment should be inspected and maintained regularly.

Water conductivity meter has the advantages of accurate measurement, easy use and simple operation. It is widely used in scientific research institutes, tap water, hospital sewage, swimming pool water, domestic sewage, aquaculture water, environmental monitoring, petrochemical, papermaking, pharmaceuticals, food, agriculture, electricity, industry, printing and dyeing, textiles, leather, brewing, electronics, universities and other industries and fields.
