Door and window hardware lacks international competitiveness

Door and window hardware lacks international competitiveness

Door and window hardware companies, taking advantage of blind spots in the development of the industry, do not pay attention to product quality, do not care about product infringement, and use branded and remanufactured rivers and lakes “cheat” to capture the market and make profits. Taking door and window hardware locks as an example, the chaotic situation of “opening a lock with one key” often occurs.

In recent years, due to increasingly fierce competition in domestic and foreign markets, although the door and window hardware companies have started industrial transformation and upgrading, due to the old production concepts, some small and medium-sized enterprises still remain in the pursuit of quantity, and product quality is difficult to guarantee.

Even bigger companies regard product innovation as the top priority of upgrading, while ignoring the quality of the product as the “pathfinder stone” of the market as the “life” of the brand, resulting in poorly controlled and unqualified products “mixing in” the consumer market, which is seriously damaging. The rights of the customer.

In fact, for door and window hardware companies, short-term benefits cannot be obtained for long-term development. With the increase in counterfeiting efforts in the country, the continuous development of the door and window hardware industry, people’s consumption levels have been improved by layers, and product brand and quality requirements have become even greater. strict. Those small and medium-sized enterprises that do not pay attention to product quality and rely mainly on “deception” will certainly be eliminated in the industry reshuffling. Finally, only the door and window hardware companies that implement product upgrades and continuously improve the quality of their products will be recognized by the market.

Door and window hardware products, only with high quality, can win the market and establish a good brand image. As the saying goes, it is easy to start a business, and if the quality of door and window hardware products cannot be upgraded, not only will the market be difficult to expand, it will be detrimental to brand building, and even these stable markets won through numerous difficulties will gradually be lost.

PH ORP Analyzer

The pH ORP analyzer includes a pH controller also called a pH transmitter and a pH sensor or ORP sensor. pH is also called acid-base value, which directly reflects the concentration of hydrogen ions in water. When the pH is greater than 7, the water is alkaline, when the pH is equal to 7, the water is neutral, and when the pH is less than 7, the water is acidic. There are many factors that affect the pH value of water, and temperature is one of them. Therefore, when measuring the pH value, it is necessary to compensate for the temperature. The pH ORP analyzer developed and produced by Daruifuno is a reliable product. We provide analog and digital two types pH ORP analyzers.


  • The pH controller is compact in shape, with small size or large size, which can meet various installation needs of customers, and we also provide matching installation accessories.

  • Since temperature has an impact on pH measurement, for more accurate measurement, the pH meter has temperature monitoring and automatic temperature compensation functions, which can be manually or automatically compensated. The matching pH sensor has a built-in temperature unit, NTC10K, PT1000, etc.
  • The pH orp analyzer has 2 SPST relays with high and low settings, which can control dosing, cleaning and temperature.
  • 2-way 0/4-20mA circuit output, which can output pH or ORP value and temperature value.
  • The online pH meter also has an RS485 interface and supports the Modbus communication protocol.
  • In addition, the pH ORP analyzer also has functions such as password setting and test maintenance.
  • The enclosure protection grade is IP66, and it can be used continuously outdoors.
  • The large-sized pH meter also has time and history functions.

The pH control process widely exists in petroleum, chemical industry, pharmaceutical, papermaking, wastewater treatment and water supply treatment. In industrial production, the pH value must be strictly controlled within a specific range, otherwise it may cause product quality degradation, waste of raw materials, production failure, and even environmental pollution. Therefore, the pH value can be controlled within a certain range by using a pH orp analyzer.
