Principle
The meter uses the Conductivity detector Electrode measurement of the conductivity of the aqueous solution, and the optional TDS conversion factor to calculate the total dissolved solids value. The automatic or manual temperature compensation mechanism is used, and the standardized temperature is 25 ° C as the reference to ensure the accuracy of measurement in different temperature environments. The built-in system menu allows users to customize several parameters, such as Electrode constant and temperature compensation coefficient, to suit different application needs.
Applications
Chemical, metallurgy, environmental protection, food industry
Standards
Industrial Instrumentation Standard Specification
Steps
1. Connect the power supply and Electrode.
2. Set parameters such as Electrode constant, temperature compensation factor and alarm limit through the built-in system menu.
3. Use the calibrating liquid for 1 to 3 point calibrating.
4. Select manual or automatic temperature compensation mode.
5. Begin measurement of conductivity or TDS value.
6. Monitor 4 to 20mA signal output or RS485 communication data.
7. If necessary, use the one-click reset function to restore the default settings.
Notice
• Make sure the power supply is DC24V to avoid overvoltage use.
• Use the specified calibrating solution (e.g. 84uS/cm, 1413uS/cm, 12.88mS/cm, 111.8mS/cm) to calibrate.
• Select the appropriate Electrode constant (K = 0.1/1/10) and TDS conversion factor (0.1~ 1.0) according to the water quality.
• Operating temperature range is 0~ 60 ℃, avoid operating in extreme environments.
• Regularly check Electrode status to ensure Measurement accuracy.
• The high/low alarm setting range is within 0.02uS/cm~ 20.0mS/cm to avoid setting beyond the range.
• The maximum load of the signal output is 500Ω to prevent overload damage.
• The setting range of temperature compensation coefficient is 0.0~ 10.0%/℃, which needs to be adjusted according to the actual application.
