DURABLE ELECTRODE：GRT1130

The “stable tool” GRT1130 pH electrode works effectively in high-viscosity, clog-prone conditions. When working with thick suspensions, emulsions, and protein-rich thick liquids, ordinary electrodes often have interface blockage, hard maintenance, and poor adaptability. Disassembling and washing objects reduces efficiency, and viscous medium causes data drift. A solid gel dielectric and two-point ceramic core liquid contact prevent sticking and maintenance. Standard universal interface, double sheath adaption, different lengths. This allows it to monitor complex media in environmental protection, chemical manufacture, electroplating, and other industries using foreign electrodes. It also makes viscous measurements painless and stable.

Adaptation scenario:

  • Online monitoring of sewage treatment: continuous pH monitoring of industrial wastewater and biochemical treatment wastewater, anti blocking design to deal with suspended impurities in water, and dual protective sleeves suitable for different corrosive environments;
  • Application in the electroplating industry: monitoring of plating solution, online monitoring of chromium removal process, resistance to medium impurity erosion, and optional length to adapt to different plating tank depths;
  • Production of viscous media: pH measurement of viscous liquids such as pulp, starch, mud, sugar, etc., with anti sticking and anti blocking properties to avoid medium adhesion and ensure continuous measurement;
  • Multi scenario adaptation in the chemical industry: monitoring complex media in industries such as chemical drugs, dyes, and mining, combining multiple lengths and double sheaths to adapt to different installation requirements such as pipelines and containers;

Maintenance

  • Daily cleaning: Rinse the electrode with distilled water before and after measurement, gently absorb moisture with filter paper to avoid residue of viscous media;Deep cleaning once a week to clear the liquid interface;
  • Sediment treatment: When the glass film appears semi transparent or adhered, soak it in dilute hydrochloric acid for 5-10 minutes, rinse with clean water, and do not scratch it with hard objects;
  • Idle storage: After washing, put on a protective cover containing 3.3Mol/L KCL solution and place it in a dry and ventilated place. Dry storage is strictly prohibited from causing the sensitive film to fail;
  • Regular calibration: It is recommended to calibrate once a week with standard calibration solution to ensure measurement accuracy; In scenarios with high levels of viscous media or impurities, calibration can be shortened to every 3-4 days;
  • Taboo: Avoid long-term immersion in distilled water, protein solutions, or acidic chloride solutions, stay away from organic silicon oils and fats, and prevent electrode performance degradation.

Sensor diagram illustration

  1. After opening the packaging, check whether there is mechanical damage to the sensitive bulb and electrode body of the sensor.
  2. 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;
  3. Select the corresponding sensor sleeve or cable head for installation according to different sensors;
  4. 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.

Technical Support

The two-point ceramic core liquid interface increases the ion conduction area, and the ceramic material has uniform pores, which can effectively block the adhesion of suspended particles and proteins in viscous media; Ordinary junctions are often designed as single points and are prone to blockage by impurities, while two-point structures can form dual conduction channels. Even if one part is slightly blocked, the other part can still work normally, greatly reducing the probability of blockage and reducing the frequency of disassembly and cleaning.

The core performance (accuracy, anti blocking, response speed) of different lengths is completely consistent, only the installation adaptability is different. Choosing the wrong length can affect usage: if the length is too short, the electrode bulb and liquid network cannot be completely immersed in the viscous medium, resulting in inaccurate measurements; If the length is too long, it may touch the bottom of the container or the inner wall of the pipeline, causing electrode damage or measurement interference. It is recommended to measure the installation depth first before selecting the appropriate type.

Solid gel dielectrics do not need to be supplemented, which avoids the problems of liquid dielectrics that are easy to run off and leak, and makes maintenance easier; At the same time, the gel has a strong sealing structure, which can effectively isolate the impurities in the viscous medium and prevent the internal pollution of the electrode; In the high temperature (0-100 ℃) environment, gel is stable, and its performance will not fluctuate due to temperature changes. Compared with liquid dielectrics, it has better stability and service life in complex working conditions.

No special maintenance is required, but two points should be noted: first, avoid direct contact of electrodes with high-temperature heat sources to prevent local overheating and damage to sensitive membranes; Secondly, the flowability of viscous media is worse at high temperatures, and it is necessary to increase the cleaning frequency to avoid medium adhesion and blockage of the liquid interface; The calibration cycle can be appropriately shortened to ensure stable measurement accuracy in high-temperature environments, and the remaining maintenance procedures are consistent with conventional working conditions.
