In recent years, environmental protection has become the focus of attention as environmental issues have become increasingly prominent. For wire and cable companies, manufacturing green products is of great significance to companies. The development and large-scale application of green wire and cable has become an international trend. Wire and cable companies implement green environmental protection management and control and achieve green manufacturing, which has become an important way to increase the competitiveness of cable companies in the international market. “Green cables are those that meet specific performance requirements, include reasonable expectations, are non-toxic to humans and the environment, have no pollution, are highly safe and reliable, have a long service life, are easy to break up, and are recycled. The characteristics of the circular economy model, etc.†Zhu Ronghua, secretary-general of the Opto-Electronics Branch of China Electronic Component Industry Association, said at the 2013 China Asia Wire & Cable International Summit held in Shanghai on October 17th. In fact, wire and cable may contain harmful heavy metals such as lead in the production process and in raw materials. In order to standardize the materials and process standards of electrical and electronic products, to make them more conducive to human health and environmental protection, more and more environmental protection laws and regulations have become more and more strict in the world. A mandatory standard RoHS Directive (“Directive on the Restriction of the Use of Certain Harmful Substances in Electrical and Electronic Equipmentâ€) developed by the EU legislation, which applies to lead, mercury, cadmium, hexavalent chromium, and polybrominated biphenyls in electrical and electronic products. A total of six substances of polybrominated diphenyl ether were defined: In addition, all chemicals that are to be imported and produced in Europe must comply with the REACH directive. Compared with RoHS, the REACH directive covers a wider range of industries, from the mining industry to textiles and garments, light industry, electromechanical and other products and manufacturing processes in almost all industries. The REACH Directive imposes very strict restrictions on the use of chemicals that are harmful to the human body and the environment. It requires that the content of any substance of very high concern (SVHC) with an annual usage of more than 1 ton cannot exceed 0.1% of the total weight of the total goods. As of April 7, 2013, the list of SVHC has been Cadmium, cadmium oxide, di-n-pentyl phthalate, lead tetrafluoroborate, lead zirconium titanate and other 144 hazardous chemicals. Grasping the latest global green environmental protection regulations, optimizing corporate standardization systems, and establishing a green corporate image, Chinese cable companies can improve their overall competitiveness internationally. The digital PH ORP Controller is designed for digital pH and ORP sensors. As a controller for water quality analysis, daruifuno's digital pH ORP controller is equipped with 2 SPST relays, which can set high and low alarms, control the dosing of the dosing pump, and keep the pH of the solution within a certain range.
The digital PH ORP Analyzer can only be connected with the digital sensor, and the controller itself also has an RS485 interface and supports the MODBUS communication protocol. The large size of the digital ph orp meter is 120*120*144mm, suitable for panel, wall and pipe installation, and we provide installation accessories.
The digital pH ORP controller also has time and historical data functions, and saves the latest 100 maintenance records, which is more convenient for customer management.
