How to choose a pen conductivity meter?

Pen-type conductivity meter is a portable instrument used to measure the conductivity of solution, which is often used in water quality testing, food processing and pharmaceutical fields. The following is a detailed introduction to the selection points and precautions:

select points

Measuring range: When selecting a conductivity meter, the required measuring range should be considered. Different conductivity meters have different ranges, so it is necessary to select an appropriate range to ensure that the required conductivity value can be measured.

Precision and Accuracy: Precision and accuracy are also very important considerations when selecting a conductivity meter. Higher precision and accuracy can ensure more accurate and reliable measurement results.

Display screen: Conductivity meters are usually equipped with a display screen, so choose a conductivity meter with a clear, easy-to-read display screen.

Battery Life: When choosing a conductivity meter, battery life needs to be considered. A conductivity meter with long battery life can reduce the frequency of battery replacement, so it is more convenient and economical.

Functions and Features: Some conductivity meters also have additional functions and features such as automatic temperature compensation, data storage, automatic shutdown, etc. The corresponding functions and features should be selected according to actual needs.

Precautions

Calibration: Before taking measurements with a conductivity meter, calibration is required. Calibration should be performed before and after use to ensure the accuracy and precision of the measurements.

Cleaning and Maintenance: Regularly clean and maintain the conductivity meter to ensure the normal operation and accuracy of the instrument.

Protect the instrument: The conductivity meter is a precision instrument and should be handled with care to avoid collisions, drops, and moisture intrusion. When not in use, store it in a dry, clean place away from direct sunlight and high temperatures.

Operating specifications: To operate the conductivity meter, it should be operated according to the operating specifications in the manual to avoid inaccurate measurement results or damage to the instrument due to misoperation or improper use.
