The GRT1120DW pH sensor is a professional tool for monitoring that was made to deal with the problems that come up with high viscosity suspensions, emulsions, and protein-containing liquids in factories. Some of these situations are treating wastewater, getting rid of chromium through electroplating, and making pulp and starch. Using regular electrodes either causes data drift because of material that blocks them or means that the electrolyte needs to be replaced often, which costs a lot of money to maintain.

Accurately adapting to the scene
- Environmental protection field: online monitoring of biochemical and sedimentation tanks in sewage treatment plants, real-time pH control of chromium removal processes in the electroplating industry – able to withstand corrosion and blockage from slag containing wastewater and electroplating solutions;
- Chemical and Light Industry: Measurement of pH in the production process of chemical drugs, dyes, and pigments, monitoring of viscous materials in pulp mills, starch mills, and sugar mills – suitable for high concentration suspended particles and protein containing viscous media;
- Special working conditions: pH detection of protein containing liquids in food processing and some viscous liquids in the pharmaceutical industry (with hygiene grade protective sheaths) to avoid frequent replacement of ordinary electrodes due to blockage.
Usage and Maintenance Guide
To maximize the performance and extend the lifespan of GRT1120DW, it is important to pay attention to these practical points:
- Before measurement, clean the sensor with distilled water and absorb the moisture to ensure that the bulb and the liquid junction are submerged in the measured liquid at the same time, avoiding impurities from entering and affecting the data;
- Soak in 3.3Mol/L KCL solution when idle, and avoid long-term immersion in distilled water, protein solution, or acidic chloride solution. Keep away from organic silicon oils and fats;
- Clean and calibrate once a week, wash the glass film sediment with dilute hydrochloric acid, and prohibit scratching the sensitive film with a hard brush;
- Strictly follow the HF concentration resistance specifications to avoid sensor damage caused by over concentration and over temperature conditions.
Sensor diagram illustration
- After opening the packaging, check whether there is mechanical damage to the sensitive bulb and electrode body of the electrode;
- Remove the sensor protective cover and check if there are any bubbles in the sensitive bulb of the electrode. 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 electrodes;
- 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.

GRT1120DW can stably catch viscous sludge from sewage treatment, slag containing liquid from electroplating workshop, and high viscosity material liquid from pulp mill – the frustrating scenes in industry where “ordinary electrodes get clogged and need to be replaced every three days”. Its anti blocking structure saves the cost of frequent electrode replacement, the maintenance free design saves the energy of operation and maintenance personnel, and stable data supports the smooth production process.
