Conductivity detector is an instrument used to measure the conductivity of solutions, widely used in water quality monitoring, environmental protection, chemical industry, food, medicine and other fields. Its main characteristics can be reflected from multiple dimensions such as measurement performance, functional design, and ease of use, as follows:

1、 High precision measurement capability

·Wide range coverageCan adapt to the measurement needs of solutions of different concentrations, with a range typically ranging from0.01μS/cmto1000mS/cm(Even higher), it can cover the detection of pure water, ultrapure water to high concentration electrolytes.

·High resolution and accuracy: Resolution up to0.001μS/cmMeasurement errors are usually within±0.5%Within (some high-precision models are available)±0.1%）Ensure the reliability of the data.

·Temperature compensation functionThe conductivity of a solution is significantly affected by temperature. The instrument is equipped with a built-in temperature sensor (or supports an external probe), which can automatically correct the measured value based on temperature (usually measured by 25℃As a benchmark, reduce the interference of environmental temperature fluctuations on the results.

2、 Diversified functional design

·Multi parameter integrationMany models can not only measure conductivity, but also simultaneously measure total dissolved solids（TDS）Parameters such as salinity and temperature meet the requirements of multi scenario detection.

·Data storage and outputEquipped with data storage function (capable of storing thousands of sets of data), supportingUSBTheRS232Export data through the interface or print directly through a printer for easy data recording and analysis.

·Calibration functionSupport manual or automatic calibration, some instruments have multiple built-in standard calibration points (such as1413μS/cmThe12.88mS/cmEnsure measurement accuracy during long-term use.

·alarm functionThe conductivity upper and lower limit thresholds can be set. When the measured value exceeds the range, an audible and visual alarm will be triggered, which is suitable for real-time monitoring scenarios (such as industrial water treatment).

3、 Design to adapt to different scenarios

·Difference between portable and desktop：

oPortable instrument: small in size, light in weight, equipped with rechargeable batteries, suitable for field inspections (such as water source patrols), easy to operate and strong anti-interference.

oDesktop instruments: higher precision, more comprehensive functions, suitable for long-term continuous monitoring in laboratories or fixed locations, and some support online real-time monitoring (with flow tanks).

·corrosion resistanceElectrodes are often made of corrosion-resistant materials such as platinum and titanium alloys, and the outer shell is usedABSOr stainless steel, which can adapt to complex solution environments such as acid and alkali.

·Online monitoring adaptationIndustrial grade models support online installation and can monitor the conductivity changes of solutions in pipelines in real time, with fast response speed (usually ＜1 Meet the demand for automated production in seconds.

4、 Convenience of operation and maintenance

·Visual display: Equipped withLCDorOLEDThe screen clearly displays measurement values, temperature, calibration status, and other information, and some support backlighting to adapt to dim environments.

·Simple operationThe button layout is simple, supporting one click measurement and calibration, and some have Chinese menus, reducing the threshold for use.

·Low maintenance requirementsThe electrode can be disassembled for cleaning or replacement, the instrument has low power consumption (especially portable), and the long-term use cost is low.

5、 Targeted optimization of application scenarios

·Laboratory level: focuses on high precision and stability, used for scientific research or precision analysis.

·Industrial grade: emphasizes anti-interference ability, durability, and online monitoring function, adapting to harsh environments in factories.

·Water quality monitoring: optimized for scenarios such as drinking water and sewageTDSThe conversion accuracy with conductivity meets relevant industry standards (such asGB/T 6908-2018Methods for analysis of boiler water and cooling water - Determination of electrical conductivity.

In summary, the core feature of a conductivity detector isHigh precision, multifunctional, and strong adaptability to different scenariosIt can meet the precision analysis requirements of laboratories and also adapt to real-time monitoring of industrial sites, making it an important tool for detecting solution ion concentration.
