Scope of Application
- Used for detecting the oxidation-reduction potential of circuit boards and chromium containing wastewater treatment.
Four core advantages define industrial grade reliability
Strong anti poisoning effect
The gel dielectric salt bridge technology can specifically block toxic ions such as S ² ⁻ and CN ⁻, and its service life is more than 50% longer than that of ordinary electrodes.
Anti pollution and anti blockage
The annular PTFE liquid interface design is not easy to adhere to suspended solids, and can operate stably even in highly polluted mud and water. It is maintained only once a month.
Low maintenance design
Solid gel dielectrics do not need fluid replacement, and the terminal blocks are easy to install, saving 80% of the labor cost for the operation and maintenance team.
Strong anti-interference ability
Enhanced shielded cables have excellent resistance to electromagnetic interference, ensuring stable and reliable data even in complex industrial electromagnetic environments.
Accurately adapting to the scene
Chromium containing wastewater treatment:
Accurately capturing the ORP changes of chromium containing wastewater, providing data basis for the reduction of chromium ions, and ensuring that the treatment effect meets environmental discharge standards.
Circuit board wastewater treatment:Real-time monitoring of the oxidation-reduction potential of wastewater from circuit board fabrication helps control the chemical reaction process and makes sure that the treated wastewater fulfills the needed standards.

Usage and Maintenance Guide
Measurement and Calibration Standards
- When measuring, it is necessary to ensure that the testing part of the sensor and the reference liquid network are both immersed in the measured liquid to avoid data deviation due to insufficient contact.
- ORP standard solution preparation: 50ml pH 4.00 standard buffer, add an appropriate amount of quinone hydroquinone reagent and stir until saturated. After preparation, use immediately and do not store for a long time;
- The sensor standard solution (saturated quinone hydroquinone solution) has a storage time of only 48 hours and needs to be re prepared if it exceeds the expiration date.
Key points for cleaning and maintenance
- If the platinum electrode is contaminated with oil, cotton dipped in acetone or alcohol can be used to gently scrub it; If insoluble organic matter is attached, it needs to be washed with 30-50% hydrochloric acid and then rinsed clean with distilled water.
- If left idle for a long time, the sensors should be stored properly to avoid contact with corrosive substances and prevent structural damage from affecting measurement accuracy.

- After opening the packaging, check whether there is mechanical damage to the sensitive bulb and electrode body of the sensor.
- Select the corresponding sensor sleeve or cable head for installation according to different electrodes;
- The connection between the sensor wire and the electrode is not waterproof, please make sure to do a good job of waterproofing.
Wire stripping instructions

Attention
- The outer layer of the transparent central axis is covered with a conductive rubber layer and a metal mesh layer. When stripping, first strip the metal mesh layer into the metal mesh as shown in the picture, and be sure to removal of conductive black skin on the transparent central axis;
- The cable extends to the host without any contact points except for a dedicated junction box.
