Membrane Coated Peracetic Acid Sensor With High Chemical Resistance For All Water Treatment

Membrane-Coated Peracetic Acid Sensor With High Chemical Resistance For All Water Treatment Applications

The two-electrode system membrane peracetic acid sensor P10.1 is used in all water treatments. It has a mechanically sturdy membrane system with high tolerance to chemicals. The maximum water temperature is 45°C. The optional range is 0~20/200/2000/5000/20000/50000 ppm. Its main features and advantages include the following:

Features

1. Simple two-electrode structure:
Contains working electrode and reference electrode, compact design, easy to integrate into equipment or system.
Reduces complex interactions between electrodes and improves signal stability.

2. Selective detection:
Isolates other interfering substances through membrane technology to achieve specific detection of peracetic acid.
Provides a stable background signal to avoid cross-interference.

3. Fast response time:
The high mass transfer rate of the membrane enables the sensor to respond quickly to changes in peracetic acid concentration.

4. Low maintenance requirements:
The protective effect of the membrane reduces electrode contamination and loss, extending the service life of the sensor.
Usually has automatic calibration and self-cleaning functions for daily use.

5. Wide measurement range:
It can detect peracetic acid from low concentration (ppm level) to high concentration, meeting various application requirements.

Advantages
1. High precision and stability:
The membrane method effectively reduces external interference and improves the accuracy and long-term stability of detection.

2. Chemical corrosion resistance:
The sensor material is usually made of corrosion-resistant materials to adapt to the strong oxidizing environment of peracetic acid and other disinfectants.

3. Low power consumption design:
The two-electrode system has a simple design and low energy consumption, which is suitable for continuous online monitoring.

4. Easy to install and operate on site:
The miniaturized design and plug-and-play function make it easy to deploy under various field conditions.

5. Flexible data output:
Supports multiple signal output methods (such as analog signal 4-20mA or digital communication protocol), which is easy to integrate with the control system.

6. Strong adaptability:
It can be used in different water quality conditions (such as sewage, drinking water, industrial water), and has strong tolerance to flow rate and pressure changes.
