This pH electrode, the GRT1130C, was designed specifically for use in difficult industrial settings. It offers core advantages such as anti-ion poisoning, maintenance-free operation, rapid reaction, and specific gel dielectrics that allow it to link with two-point ceramic core fluid. Additionally, it is equipped with these dielectrics. For the purpose of providing stable and accurate pH monitoring solutions for environmental protection, electroplating, water treatment, and other industries, it is appropriate for multi-media measurement of clean water, sewage, electroplating solution, and other similar substances.

Core strength
- Anti poisoning and anti pollution: gel dielectric salt bridge can effectively resist toxic ions such as S ² ⁻ and CN ⁻, and avoid electrode failure;
- Maintenance free and cost saving: No need to supplement dielectric, only need to clean and calibrate every week, significantly reducing maintenance workload;
- Wide scene adaptation: special material sensitive film, compatible with 0-14PH full range, suitable for multiple media such as pure water, sewage, electroplating solution, etc;
- Stable and efficient: low electrode internal resistance, fast response speed, strong data stability, theoretical percentage slope ≥ 95%;
- Easy installation: Standard PG13.5 thread, suitable for pipeline installation and electrode sleeve, with strong versatility.
Adaptation scenario:
- The online measurement of pure water: it can be used to keep an eye on the pH of deionized water and industrially made pure water. It is quick to respond and very accurate.
- Environmental wastewater treatment: monitoring of municipal and commercial wastewater treatment plants;, capable of resisting complex impurities and toxic ion interference in wastewater;


- Electroplating: finding the pH of the electroplating solution, watching the process of chromium removal in real time, and protecting the electroplating solution from corrosion and ion pollution;
- General industrial situations: measuring the pH of different substances at room temperature to medium-high temperature (≤ 100 ℃) in fields like chemical protection and environmental protection.
Sensor diagram illustration

- After opening the packaging, check whether there is mechanical damage to the sensitive bulb and electrode body of the sensor.
- Remove the sensor protective cover and check if there are any bubbles in the sensitive bulb of the electrode. If so, gently shake the electrode 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 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.
