DULCOTEST pH sensors ProMinent
Thang đo pH có vạch chia từ 0 – 14
Đo pH bằng cảm biến DULCOTEST: Giá trị đo chính xác, đáng tin cậy và phù hợp với ứng dụng trong thời gian thực.
Kiểm soát, điều chỉnh và giám sát các quá trình hóa học với sự hỗ trợ của các giá trị đo chính xác.
Đo pH trực tuyến đáng tin cậy – với cảm biến DULCOTEST
Việc đo và điều chỉnh giá trị pH trực tuyến cần phải chính xác, nhanh chóng và đáng tin cậy nhất có thể, đồng thời cung cấp khả năng truy cập tốt các giá trị đo được, cho dù là để giám sát, kiểm soát hay điều chỉnh các quá trình hóa học.
Dòng sản phẩm cảm biến pH DULCOTEST của chúng tôi cung cấp một loạt các cảm biến pH cho các nhiệm vụ đo lường khác nhau.
Các cảm biến pH của chúng tôi được sản xuất theo các tiêu chuẩn kiểm soát chất lượng rất nghiêm ngặt (ví dụ: tuân thủ hướng dẫn RoHS).
Các bước thông thường được tự động hóa, nhưng các bước quan trọng được thực hiện thủ công dưới sự giám sát của chuyên gia.
Bằng cách này, chúng tôi đạt được chất lượng có thể tái tạo tốt nhất và giảm chi phí.

Field of application
The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.
- Chemical processes
- Chemically contaminated water
- Swimming pool water, potable water
- Process water
- Cooling water, wastewater
- Seawater
- Suspensions, sludge, emulsions
- Exhaust air scrubber, semiconductor industry, electroplating
Monitoring and Replenishing of Electroplating Baths
Demanding baths require concentration
Baths have to be monitored and replenished continually. This requires high concentration – from the sensors, controllers and pumps. Yet only small amounts of precisely fed chemicals are needed.
Flotation in Mining
Frothers and collecting agents
To remove ore from the flotation liquid faster, activating chemicals (frothers and collecting agents) have to be accurately added by metering. Getting the right amounts is crucial.
Metering of Fluids
Incredibly simple and efficient metering of chemicals
We transport chemicals with ease in any industrial environment: ProMinent solutions store, transfer and meter substances at rates of 0.1 l/h to 100,000 l/h at a pressure of 2 to 3,000 bar.
Cooling Water Treatment
Efficiency is everything in the cooling water circuit
Everything at ProMinent revolves around the perfect cooling water circuit, which needs to experience few losses over its long life. The precise metering of inhibitors and biocides and suitable filters make this possible.
Waste Water Treatment
Very low-impact treatment for waste water
Our water treatment technology delivers thorough yet environmentally friendly waste water treatment. What’s more, with precisely metered additives and optimised processes, you also save money.
Cleaning fruit and vegetables
Simple and reliable cleaning process for agricultural products
Fresh fruit and veg are an essential part of our diet. So it’s very important for them to reach the consumer in a safe condition. Precise metering of chlorine dioxide ensures that this is the case.
Fish processing, fish and shrimp farming
Successful farming and hygienic processing
More and more people are enjoying delicacies from our seas. Fish farms and also the fish processing industry therefore face the huge challenge of producing goods quickly and hygienically. Disinfected water is essential to both industries.
Flue Gas Cleaning in Energy Generation
Flue gas cleaning for fresh air and a clean environment
ProMinent understands how to incorporate the complex flue gas cleaning process in power plants. Harmful substances are reliably removed from the air before they enter the atmosphere.
Monitoring and optimising surface treatment in electroplating
The right way to immerse items!
In order to attain a desired surface quality before taking further steps, such as painting, raw products are treated with various chemicals.
Sustainable use of water in industrial processes
Sustainable cycles
There are certainly chemicals that are more popular than hydrogen peroxide. But despite this, it has to be used in certain industrial processes, such as the disinfection of water.
