Conductivity tester is a professional instrument used to measure the conductivity of solutions, widely used in water quality monitoring, environmental testing, chemical production, biomedicine and other fields. Its main characteristics can be developed from multiple dimensions such as measurement performance, functional design, ease of use, and applicable scenarios, as follows:

1、 High precision measurement performance

·Wide range coverageThe measurable conductivity range is usually wide, ranging from low conductivity (such as pure water,μS/cmGrade) to high conductivity (such as concentrated solutions,mS/cmLevel), able to adapt to the detection needs of solutions with different concentrations.

·High resolution and accuracy: Resolution up to0.01μS/cmMeasurement errors are usually controlled within±1%Within (some high-precision models are available)±0.5%）Ensure the reliability of the data.

·Automatic temperature compensationThe conductivity of a solution is significantly affected by temperature. The instrument is equipped with a built-in temperature sensor (or supports an external temperature probe), which can automatically calibrate the measurement value based on temperature. Usually 25℃Compensate for the baseline temperature to reduce the impact of environmental temperature fluctuations on the results.

2、 Intelligent functional design

·auto-calibrationSupport calibration with standard conductivity solution, some models have multi-point calibration function (such as calibration points for different ranges), the calibration process is simple and can be completed with one click, ensuring the accuracy of the instrument for long-term use.

·Data storage and exportBuilt in storage module, capable of storing a large amount of measurement data (ranging from tens to tens of thousands), some instruments are equipped withUSBTheRS232Waiting for interfaces, supporting data export to computers or printers for convenient data recording and analysis.

·Mode SwitchIn addition to conductivity, some instruments can simultaneously measure total dissolved solids（TDS）Parameters such as salinity and temperature can be detected through mode switching to enhance practicality.

·Backlit display screen: AdoptingLCDorOLEDDisplay screen, equipped with backlight function, can still read data clearly in low light environments. The operation interface is simple and intuitive, displaying measurement values, temperature, units and other information.

3、 Convenient operation and maintenance

·Portable designSome models are compact in size and lightweight, equipped with suitcases or portable batteries, suitable for on-site field testing (such as water quality sampling points, rivers and lakes, etc.); Laboratory models place greater emphasis on stability and are typically designed as desktop models.

·Electrode compatibilitySupports multiple types of conductive electrodes (such as platinum black electrodes and bright electrodes), and suitable electrodes can be selected according to the measurement range. The electrode installation and disassembly are convenient, and it is easy to clean and replace.

·Low power consumption and durabilityPortable instruments often use battery power, with a long battery life (several hours to several days), and some have automatic shutdown functions to save power; The shell is mostly made of corrosion-resistant and impact resistant materials, suitable for use in complex environments.

4、 Widely applicable scenarios

·water quality monitoringCommonly used for conductivity testing of drinking water, surface water, industrial wastewater, and pure water (such as laboratory ultrapure water) to determine water purity or pollution level.

·industrial process controlIn industries such as chemical, pharmaceutical, food and beverage, it is used to monitor the concentration of solutions (such as electrolytes, cleaning agents, etc.) during the production process to ensure process stability.

·Research and EducationAs a basic laboratory instrument, it is used for chemical experiments, environmental science research, and can also be used as a teaching tool to explain the principle of solution conductivity.

In summary, the core feature of a conductivity tester isHigh precision, multifunctional, easy to operate, widely applicableBy optimizing measurement performance and functional design, meet the needs of solution conductivity detection in different scenarios.
