Acidimeter (also known as acidity meter)pHMeter is used to accurately measure the acidity and alkalinity of a solution（pHThe instrument is widely used in fields such as chemical engineering, environmental protection, medicine, food, agriculture, etc. Its main characteristics can be developed from multiple dimensions such as measurement performance, functional design, and ease of use, as follows:

1、 High precision measurement capability

·high accuracyThe measurement accuracy of mainstream acidity meters can usually reach±0.01pH(Laboratory level), some models can even reach±0.001pHMeet the requirements of precision experiments.

·Wide range coverage：pHThe measurement range is generally0-14pHIt can cover the measurement of strong acids, strong bases, and neutral solutions, and some models can also be extended to- 2.000to19.999pHAdapt to special scenarios (such as high concentration acid solutions).

·Taking into account other parametersMany multifunctional acidimeters can also simultaneously measure parameters such as temperature, conductivity, and dissolved oxygen of a solution, achieving synchronous analysis of multiple indicators.

2、 Intelligent and automated functions

·Automatic temperature compensationBuilt in temperature sensor (or support external probe), capable of real-time monitoring of solution temperature and automatic calibrationpHValue (due topHThe value is significantly affected by temperature, ensuring the accuracy of measurement results at different temperatures.

·auto-calibration: Support1-3Point automatic calibration (commonly used standard buffer is)pH4.00、6.86、9.18）The instrument can automatically identify the calibration solution and complete the calibration process, reducing human operation errors.

·Data storage and outputEquipped with data storage function (capable of storing hundreds to thousands of sets of data), supported by some modelsUSBTheRS232The interface can export data to a computer or printer for easy data recording and analysis.

·Intelligent reminderWhen the calibration expires, the electrode ages, or exceeds the range, the instrument will issue an alarm or prompt, improving the convenience of use.

3、 Stable measurement system

·Optimization of electrode performance: Specialized for pairingpHElectrodes (such as glass electrodes, composite electrodes) have a fast response speed (usually30 Stable within seconds, strong anti-interference ability (such as resistance to ion strength and organic interference), and some electrodes also have characteristics such as high and low temperature resistance and high voltage resistance.

·Anti interference designThe circuit system adopts shielding technology to reduce the impact of electromagnetic interference (such as surrounding electrical equipment and static electricity) on the measurement signal, especially in complex environments such as industrial sites, it performs stably.

4、 Widely applicable scenarios

·laboratory-gradeCompact in size, precise in function, suitable for laboratory scenarios such as scientific research and quality inspection, emphasizing measurement accuracy and data reliability.

·portableLightweight and easy to carry, with built-in rechargeable battery, suitable for rapid field and on-site testing (such as environmental water quality inspection, soil leachate measurement).

·Industrial online typeCan be fixedly installed on production lines (such as chemical reaction vessels, water treatment systems) to monitor solutions in real timepHValue and output control signals to achieve automated production control, with industrial grade characteristics such as high temperature resistance, corrosion resistance, and vibration resistance.

5、 Convenience of operation

·Visual display: AdoptingLCDorOLEDLarge screen, clear displaypHValue, temperature, calibration status, and other information. Some models support backlighting, making it convenient to use in low light environments.

·Simplify operationsThe button layout is simple, and calibration, measurement, and other steps can be completed with just one click, without the need for complex settings. Even beginners can quickly get started.

·easy maintenanceThe electrode can be easily disassembled and replaced, and some models are designed with electrode protective covers or storage solutions to extend the service life of the electrode.

6、 Durability and adaptability

·Material corrosion-resistantThe instrument casing is often usedABSEngineering plastics or stainless steel, resistant to impact and chemical corrosion, suitable for use in damp and dusty environments.

·Wide working temperatureThe working environment has a wide temperature range (such as0-50℃）Some industrial models can be used- 10℃to 60℃Stable operation.

In summary, the core feature of an acidity meter isHigh precision, intelligence, and strong adaptabilityIt can meet the precision measurement needs of laboratories and adapt to the complex environment of industrial production and on-site testing. It is a tool for analyzing the acidity and alkalinity of solutions.
