The KPT-4281W-VP pH sensor is mainly made of titanium alloy and combines the advantages of anti blocking, low maintenance, and high compatibility design. It solves the problems of sensor structure damage caused by strong corrosive media, data drift caused by electromagnetic interference, and difficulty in stable operation of conventional sensors in harsh monitoring scenarios such as electroplating chromium removal, chemical viscous liquids, and high-temperature sewage.

Core product advantages
Titanium alloy is corrosion-resistant and disturbance resistant, suitable for harsh working conditions:
The sensor body is made of titanium alloy material, which not only has strong corrosion resistance (can resist the erosion of electroplating solution and chemical acid and alkali wastewater), but also has excellent electromagnetic interference resistance. It can still stably output data in industrial electromagnetic dense environments, avoiding errors caused by signal interference.
Maintenance free and cost saving:
Equipped with gel dielectrics, there is no need to add additional electrolytes, only basic cleaning and calibration are required daily, the maintenance workload is greatly reduced, and it is suitable for high-frequency, unattended online monitoring scenarios.
International universal high compatibility:
Equipped with VP6 connector and PG13.5 standard thread, it can be directly interchanged with foreign electrodes without the need for additional adapter accessories, making it convenient for upgrading and replacing existing imported equipment; Support the combination of 316L stainless steel sheath or PP sheath to meet the corrosive requirements of different media.
Flexible adaptation to multiple specifications:
Five sensor lengths of 120/150/200/250/300mm are available, which can be selected according to different installation scenarios such as shallow tanks, deep tanks, pipelines, etc., to ensure that the electrode bubble and liquid junction are completely immersed in the tested liquid, ensuring the effectiveness of detection.
Accurately adapting to the scene
Electroplating and chromium containing wastewater treatment:The titanium alloy material resists chromium ions and corrosion from electroplating solutions, providing reliable input on water quality pH changes, reducing chromium ions and precipitation, and meeting wastewater discharge criteria.
Chemical complex medium detection:The chemical complex medium detection device measures PH levels in high-viscosity suspensions and emulsions in drug, dye, and pigment production, as well as viscous liquids like mining slurry and pulp mill pulp. Its anti-blocking design prevents joint blockage and ensures long-term stability.
Environmental wastewater monitoring online includes PH monitoring (0-100 ℃) from municipal and industrial plants, titanium alloy corrosion resistance for complex corrosive components, electromagnetic interference resistance for factory environments, and reliable data.
Monitoring PH of protein-containing viscous liquids in food and pharmaceutical sectors, including starch and sugar manufacture. The non-toxic, ecologically friendly PP sheath meets food grade material requirements, prevents media contamination, and ensures manufacturing safety.
Usage and Maintenance Guide
- Preparation before measurement: Clean the sensor with distilled water or deionized water, and use filter paper to absorb surface moisture (do not wipe the glass film to prevent damage to the sensitive layer); Ensure that the electrode bubble and the liquid interface are immersed in the measured liquid simultaneously to avoid data distortion caused by insufficient contact.
- Idle storage: When the electrode is not in use, clean it and put it into a protective cover containing 3.3 Mol/L KCL immersion solution to maintain the activity of the glass film; Long term immersion in distilled water (prone to dehydration failure), protein solutions (prone to adhesion and blockage), and acidic chloride solutions (accelerating corrosion) is strictly prohibited, and contact with organic silicon oils and fats (damaging sensitive membranes) should be avoided.
- Cleaning and calibration: If the glass film appears semi transparent or deposited, soak and wash it with dilute hydrochloric acid and rinse it with clean water; It is recommended to clean the electrodes once a week and complete calibration with the instrument (especially in high temperature and high impurity scenarios, which need to be shortened to once every 3-5 days) to ensure detection accuracy.
- Life assessment: If the calibration program cannot be completed after cleaning and calibration, or if the detection data continues to drift and respond slowly, it indicates that the electrode has lost its performance and needs to be replaced with a new one in a timely manner to avoid affecting process control.
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 electrode 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.

The KPT-4281W-VP pH sensor is made of titanium alloy, which makes it great for pH monitoring in tough situations. It works well in very corrosive environments, where there is a lot of interference, and when the media is complex. This includes everything from removing chromium in electroplating to dealing with thick chemical liquids, high-temperature sewage, and even food-grade situations. It can handle tough conditions because it resists corrosion and interference. It can also adapt to the needs of different businesses. It is a “durable partner” for tracking the environment and industrial processes.
