Yokogawa PH8EFP is a KCI filling type pH sensor with Ryton body which allows for a wide range of applications.
Product Introduction
Yokogawa PH8EFP sensor is a high-quality, high-precision pH measurement equipment. This sensor is made of advanced technology and high-quality materials, providing users with accurate and reliable pH measurement results.


Advantage
1. The PH8EFP sensor is mainly used to measure the concentration of hydrogen ions in the solution, accurately reflect its pH, and can accurately measure the pH value ranging from 0 to 14.
2. The sensor adopts a double-cell structure design, which can effectively reduce the penetration of water molecules, improve the performance of the Nemes effect, and ensure the effective stability of the output signal.
3. The unique blue glass wall effectively prevents the external acid and alkali measuring liquid from contacting the glass membrane, and improves the stability and accuracy of the measurement.
4. The sensor can work continuously in the range of 0-130 °C, meeting the needs of pH measurement in high temperature environments.
5. It has high sealing performance and can withstand a working pressure of up to 3 kg/cm2.
6. The optimized internal reference sensor design can effectively resist the influence of KCL crystallization on the sensor performance and improve the anti-chemical pollution performance.
7. The unique design of the electric gap simplifies the fluid replacement process, and the measurement fluid can be easily replaced as needed.
8. It meets the needs of general industrial measurement and can be widely used with other analytical instrument products of Yokogawa Electronics.

Yokogawa PH8EFP sensor uses high-quality glass membrane material. The material has high corrosion resistance and can fully increase the sensitivity during pH measurement. To enhance the durability of the sensor, Yokogawa also applied a protective film to the surface of the sensor. This protective film can effectively prevent the adverse effects of external environmental pollutants on the sensor and ensure the reliability of the measurement results.

In the process of using the Yokogawa PH8EFP pH sensor, you can freely adjust the detection parameters and set the correction method independently. This greatly increases the user's flexibility and autonomy when performing pH measurements. Cooperating with measuring instruments manufactured by Yokogawa, users can quickly and conveniently perform pH calibration to achieve high-precision measurement.
Application
1. PH8EFP sensors can accurately measure water quality monitoring, including sewage, waste water, etc., and are used to control the sewage treatment process.
2. It is used to measure the pH of solutions in various chemical production processes to ensure product quality control and the stability of the production process.
3. It is used to detect the acidity and alkalinity in beverages such as wine and fruit juice to ensure the safety of the production process.
4. It can be used for pH determination in pharmaceutical production to ensure the quality of pharmaceuticals and the safety of the production environment.
5. It is used to monitor the corrosive pH of hydrochloric acid and nitric acid in the smelting process, optimize the process and ensure the safe operation of the equipment.
Yokogawa PH8EFP sensor has excellent anti-interference performance. Due to its dual-stimulation working form, the product can still provide accurate pH measurement data even in environments with high or low temperature, pressure and the presence of various chemical substances. At the same time, it is equipped with a low-noise signal processing module inside, thus ensuring the high quality and stability of the sampling signal.
