Digital conductivity meter is a device for measuring conductivity, usually used in laboratories in the fields of analytical chemistry, life science and environmental science. The following will introduce the selection points and precautions of the digital display conductivity meter in detail.
select points
Measuring range: Select the appropriate measuring range according to the experimental requirements. Normally, the measurement range of digital display conductivity meters ranges from 0.001 μS/cm to 200 mS/cm.
Accuracy: Choose a digital conductivity meter with high precision to ensure the accuracy of the measurement results. Normally, the accuracy of the digital display conductivity meter is between 0.1% and 1%.
Display screen: choose an easy-to-read digital conductivity meter, it is recommended to have a large screen display and backlight function, so that the experimenter can read the measurement results under different light conditions.
Automatic temperature compensation function: The digital display conductivity meter should have automatic temperature compensation function to eliminate the influence of temperature on the conductivity measurement results.
Data storage function: choose a digital display conductivity meter with data storage function, so that the experimenter can check the historical data and perform data analysis.
Ease of operation: The operation of the digital display conductivity meter should be simple and easy, and the instruction manual should be clear and easy to understand.
Precautions
Calibration: Before using the digital conductivity meter, it needs to be calibrated to ensure the accuracy of the measurement results.
Cleaning: Before each use of the digital display conductivity meter, the probe needs to be cleaned to avoid contamination from affecting the measurement results.
Maintenance: Regularly maintain the digital display conductivity meter, including replacing the battery, cleaning the device, checking the probe, etc., to ensure the normal operation of the device.
Prevent impact: The digital display conductivity meter is a precision equipment, and care should be taken to prevent impact and collision to avoid damage to the equipment.
Temperature control: The digital display conductivity meter should be measured under constant temperature conditions to eliminate the influence of temperature on the conductivity measurement results.
