GRT1110 pH electrode is a “manufacturing expert” for industrial complex media! Whether it is colloidal media, industrial wastewater, or scenarios containing toxic ions such as S ² ⁻ and CN ⁻, ordinary electrodes are either easily contaminated and blocked, or “poisoned” by ions and become ineffective, making maintenance both labor-intensive and costly.
It is equipped with a gel electrolyte salt bridge and a circular polytetrafluoroethylene junction. It has a dual online anti poison and anti blocking function. The electrolyte free system also responds quickly. With standard interfaces and flexible installation methods, it can easily cover all kinds of industrial process monitoring, making the measurement of complex working conditions stable and easy.

Core product advantages
Antitoxic without failure: gel electrolyte salt bridge design can effectively resist the corrosion of toxic ions such as S ² ⁻, CN ⁻, and avoid electrode poisoning
Anti blocking and anti pollution: The circular polytetrafluoroethylene interface has a smooth surface without impurities, and long-term online monitoring is also not easy to block
Maintenance free and easy: gel electrolyte is pre charged at one time, and there is no need to supplement the whole process, greatly reducing the on-site operation and maintenance workload
Stable and fast response: The electrode has low internal resistance, and when facing complex media such as colloids and sewage, the data response is fast and stable
Wide installation adaptability: standard PG13.5 thread, supports pipeline installation or sleeve matching, compatible with various acidity meters
Dual compatibility of connectors: using BNC standard connectors or pin type wiring terminals to adapt to different device interfaces without the need for additional adapters
Ideal Application Scenarios
- Industrial wastewater treatment: adapted for industrial wastewater monitoring in industries such as chemical, printing and dyeing, metallurgy, etc., with anti toxic and anti blocking design to deal with toxic ions and suspended impurities in wastewater;
- Colloidal medium measurement: Accurately measure the pH value of various colloidal raw materials and colloidal chemical products. The special sensitive membrane material avoids medium adhesion and measurement does not drift;
- Conventional industrial processes: pH monitoring in industries such as chemical, electronics, and pharmaceuticals, compatible with pipeline or container installation, and suitable for continuous production needs;
- Monitoring of toxic ion media: It can deal with industrial media containing S ² ⁻, CN ⁻ and other substances that are prone to electrode poisoning. Salt bridges effectively isolate toxic ions and extend their service life;

Usage and Maintenance Guide
Installation key points
- Open box inspection: Confirm that there is no mechanical damage to the sensitive bulb and electrode body. If there are bubbles in the bulb, gently shake it vertically to remove them;
- Interface installation: PG13.5 threaded interface is used, matched with corresponding protective sleeve or cable head, and pipeline installation method can be selected to ensure stable fixation;
- Stripping specification: Peel off the metal wire layer, thoroughly remove the conductive black skin of the transparent central axis, and avoid signal interference;
- Waterproof protection: If the electrode wire connection is not waterproof, it needs to be sealed with sealant, heat shrink tubing, or waterproof joints to prevent moisture;
- Connector adaptation: Depending on the type of acidity meter interface, choose BNC standard connectors or pin type terminal blocks for docking to ensure good contact.
Maintain
- Daily cleaning: Rinse the electrode with distilled water before and after measurement, dry the filter paper to prevent impurities from entering the measured liquid; Clean thoroughly once a week to ensure performance;
- Idle storage: After washing, put on a protective cover containing 3.3mol/L KCL solution and store in a dry and ventilated place to prevent sensitive bubbles from drying out;
- Sediment treatment: When the glass film appears semi transparent or deposited, wash it with dilute hydrochloric acid and then rinse it with distilled water to avoid scratching with a hard brush;
- Calibration cycle: It is recommended to calibrate the instrument once a week to ensure measurement accuracy;
- Taboo: Avoid prolonged immersion in distilled water, protein solutions, or acidic chloride solutions, and do not come into contact with organic silicone oils.

- After opening the packaging, check whether there is mechanical damage to the sensitive bulb and sensor body of the electrode;
- Remove the sensor protective cover and check if there are any bubbles in the sensitive bulb of the sensor. If so, gently shake the sensor in a vertical plane to remove the bubbles;
- Select the corresponding sensor sleeve or cable head for installation according to different sensors;
- The connection between the sensor wire and the sensor 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.
