1、 Equipment name: conductivity meter

2、 Specification and model: CM-230

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

Conductivity meter is an on-line water quality analysis instrument with wide temperature range for medical multi effect distilled water system, boiler bottom water, condensate, heat exchange system, industrial hot cleaning of mechanical parts, industrial circulating water and other high-end water quality management and automatic control. The definition of conductivity is that electrolyte solution exists in the form of electric ions in aqueous solution, so the solution has the property of conducting electricity, and the strength of its conductivity is called conductivity.

5、 Working principle:

Conductivity is the ability of a solution to conduct current in numbers. The conductivity of water is related to the content of inorganic acid, alkali and salt. When their concentration is low, the conductivity increases with the increase of concentration. Therefore, this index is often used to predict the total concentration or salt content of water ions.

(1) Conductivity and water hardness:

The conductivity of aqueous solution is directly proportional to the concentration of dissolved solids, and the higher the solid concentration, the greater the conductivity.

(2) Soft and hard water:

Water is soft water and hard water. Water without or containing a small amount of calcium and magnesium ions is called soft water, and vice versa. If the hardness of water is caused by sodium bicarbonate or magnesium bicarbonate, it is temporary hard water (boiling temporary hard water, decomposing sodium bicarbonate, precipitated by insoluble carbonate generated, water changes from hard water); if it is caused by sulfate or chloride containing calcium and magnesium, it is permanent hard water. According to the total hardness value of water, the total hardness of 0-30ppm is called soft water, the total hardness above 60ppm is called hard water, the total hardness of high-quality drinking water is less than 25ppm, and the total hardness of high-quality soft water is below 10ppm. In natural water, rainwater and snow water far away from the city are soft water; spring water, stream water, river water and reservoir water are mostly temporary hard water, and some groundwater belongs to high hardness water.

(3) Conductivity:

Conductivity is the ability of a substance to transmit current, relative to the resistance value, in Siemens / cm.

(4) Water hardness:

The hardness of water refers to the concentration of calcium and magnesium ions in water. The unit of hardness is ppm. 1ppm represents the content of calcium carbonate in water, 1mg / L (mg / L).

6、 Performance features:

● All Chinese display, friendly interface: all data, status and operation tips are displayed in Chinese, without any symbol or code defined by the manufacturer.

● Simple menu structure, text-based human table dialogue: it is more clear and convenient to use, and can be operated according to the prompts on the screen.

● Multi parameter display: simultaneously display conductivity, output current, temperature, time and status.

● Automatic compensation of (ultra) pure water: for ultra pure water, automatic temperature compensation of conductivity at 25 ℃ is realized.

● Notepad function: faithfully record the operation and use of the instrument and the occurrence time of alarm, which is convenient for management.

● Historical curve and digital recorder function: the secondary meter can automatically store the measured data every 5 minutes, which can continuously store the conductivity of one month.

● Digital clock function: display the current time and provide time reference for digital recorder function.

● Backlight function: it can be used in low light or no light environment, and automatically adjust the contrast to the clearest according to the temperature change.

● The watchdog program ensures that the instrument will not crash, which is the basic requirement of on-line instrument.

● Output current setting and checking function: manual current source function can check and arbitrarily set output current value, which is convenient to detect recorder and lower computer.

● Current output mode set by software: 0 ~ 10mA or 4 ~ 20mA output is selected for software.

7、 Precautions:

1. The lead wire of the electrode should not be wet, otherwise it will be inaccurate.

2. High purity water should be measured quickly after being put into the container, otherwise the conductivity will increase quickly, because CO2 in the air dissolves into water and becomes carbonate ion.

3. The container containing the measured solution must be clean and free of ion contamination.
