FLEXIBLE pH ELECTRODE：GRT1130-AS7

The GRT1130-AS7 pH electrode is a “flexible adaptation king” that clogs easily and fits many purposes! Do you frequently find mismatched interfaces, improper installation depth, and obstructions when monitoring wastewater and electroplating solutions, protein-containing suspensions, or high-viscosity suspensions? Ordinary electrodes feature a single interface that is hard to replace or a poorly suited length that requires regular electrolyte refilling. It has flexible double interfaces, lengths, and sheaths. It has gel electrolyte+two-point ceramic core anti-blocking. Maintenance-free may immediately replace foreign electrodes, covering challenging working conditions in environmental protection, chemical industry, electroplating, and other industries, making viscous media measurement accurate and easy.

Core strength

  • Anti blocking and anti sticking without jamming: gel electrolyte+two-point ceramic core liquid interface, designed for viscous media, suspended particles and proteins are not easy to stick and block, and long-term online stability
  • Multi dimensional flexible adaptation: 120/150/200/250/300mm with multiple length options, 316L stainless steel/PVC double sheath, suitable for different installation depths and corrosive media
  • Maintenance free and worry free: No need to replenish electrolytes, minimal maintenance required, only simple cleaning and calibration needed per week, reducing on-site operation and maintenance costs
  • Wide working condition durability: working temperature of 0-100 ℃, pressure resistance design of 0-0.3Mpa, able to withstand temperature and pressure fluctuations in industrial working conditions without failure
  • Accurate and reliable measurement: 0-14 full range coverage, zero potential of 7 ± 0.5mV, theoretical percentage slope ≥ 95%, small data drift, fast response

Adaptation scenario:

  • Online monitoring of sewage treatment: constant monitoring of pH levels in industrial and biochemical wastewater, a design that prevents clogging to deal with suspended pollutants in water, and dual protective sleeves that work in different corrosive situations;
  • In the electroplating business, it is used to keep an eye on the plating solution, the process of removing chromium online, and the resistance to medium impurity erosion. It can also be made longer to fit different plating tank depths.
  • Production of viscous media: measuring the pH of thick liquids like pulp, wheat, mud, sugar, and others that don’t adhere or block to avoid medium adhesion and make sure the measurement is always right;
  • Adaptation to different situations in the chemical industry: monitoring of complex media in industries including chemical medicines, dyes, and mining, with dual interfaces, numerous lengths, and dual protective sleeves that function for different installation demands 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 core advantage is adaptability without blind spots! Whether the on-site equipment is an S8 socket or a PG13.5 threaded interface, it can be directly docked without the need to purchase additional adapters; When replacing foreign electrodes, there is no need to modify the equipment interface, and it is compatible with more brands and models of pH meters, reducing the cost and difficulty of equipment upgrades or accessory replacements, especially suitable for industrial scenarios where multiple devices are mixed.

There are three common reasons: first, the liquid interface is severely blocked by viscous impurities; second, the sensitive membrane is damaged or contaminated with organic silicone oil; third, long-term use beyond working conditions leads to electrolyte failure. Solution: First, thoroughly clean the liquid interface and sensitive membrane as required, activate them, and then recalibrate them; If calibration is still not possible, check whether the electrode has been in contact with taboo media or used for a long time under high temperature and pressure. After confirming the electrode failure, it should be replaced in a timely manner.

The anti-blocking effect can last for the entire life of the electrode with regular maintenance! The two-point ceramic core expands the region where ions can flow, and the gel electrolyte is very good at sealing things off, which stops suspended particles and proteins from sticking together in thick liquids. Even in high-viscosity suspensions or emulsions, the liquid interface can stay clear for a long time without having to be taken apart and cleaned often, as long as it is cleaned once a week as needed.

Not easily ineffective! The combination of gel electrolyte and two-point ceramic core can effectively resist protein adhesion and can be used stably as long as it is maintained as required. The key to avoiding failure is to clean with distilled water in a timely manner after measurement to remove surface residues; Secondly, shorten the calibration cycle and promptly correct data drift; Thirdly, do not soak in pure protein solution for a long time. When idle, soak in KCL solution as required to maintain electrode activity.
