Product Description

Product Description

RS485 PH SENSOR

The pH sensor (also known as pH electrode or pH probe) is a core detection device based on electrochemical principles, which accurately quantifies the acidity and alkalinity of solutions. Its core value lies in efficiently converting the difficult-to-directly-measure hydrogen ion activity into collectible and analyzable electrical signals. It is widely used in various industries where precise control of acid-base balance is required, serving as a key sensing device to ensure process safety, product quality, and ecological health. It completely replaces the cumbersome operation of traditional colorimetric methods, enabling real-time, precise, and continuous monitoring of pH values, and is suitable for all scenarios from laboratory precision analysis to industrial harsh environment monitoring.

Core Working Principle 
This product adopts advanced electrochemical detection technology. Its core is composed of a composite electrode structure consisting of an indicator electrode, a reference electrode, and a temperature compensation electrode, strictly following the Nernst equation to achieve precise signal conversion. The sensitive membrane of the indicator electrode (mainly glass sensitive membrane, and ISFET ion-selective membrane is equipped in special scenarios) selectively adsorbs hydrogen ions in the solution, forming a membrane potential with the internal electrolyte; the reference electrode (mostly silver/silver chloride electrode) provides a stable and unchanging reference potential, serving as a "ruler" to measure the changes in the membrane potential; the temperature compensation electrode (PT1000 platinum resistance) collects the solution temperature in real time, automatically correcting the influence of temperature on the measurement results to ensure the accuracy of data in different temperature environments. Some high-end models adopt GLI differential sensor technology, replacing the traditional dual-electrode with a three-electrode system, effectively reducing the contamination of the reference electrode, eliminating closed-loop circulation, lowering the cost of faults and maintenance, and further enhancing the reliability of measurement.

Specification

High-precision monitoring with reliable data

Full-scenario compatibility and easy installation

The measurement range covers 0 - 14 pH (full range), with an accuracy of ±0.01 pH and a repeatability of ≤ ±0.02 pH. At 25°C, the Nernst slope is close to the ideal value of 59.16 mV/pH. The long-term drift can be controlled within ±0.02 pH/month, meeting the ISO 10523 water quality testing standards. It is suitable for scenarios with extremely high precision requirements such as scientific research and high-end manufacturing. It supports two-point/three-point automatic calibration, which can quickly eliminate systematic errors and ensure stable and repeatable measurement data, avoiding process failures or product non-conformity caused by pH deviations.

It supports various installation methods such as immersion type, circulation type, insertion type, and hygienic type. No additional modification is required to adapt to the environment, and it can be flexibly applied to the installation needs of different scenarios. The protection level reaches IP68, with excellent waterproof sealing performance. It can work for a long time submerged in water and also has good shock resistance, suitable for outdoor and complex environments with high vibration. It is equipped with low-noise dedicated cables, and the signal transmission distance can reach over 20 meters without interference, avoiding the influence of external signals on the measurement data.
