Currently automatic monitoring equipment for particulate matter, mainly from the US and European imports, domestic technology is relatively weak, poor stability, life is short, the overall maturity is not enough, basically related fields put to use imported equipment. To achieve the level of compliance with the conditions, and the run continued, stability dominated all aspects of the product, only imported products to meet. If your company needs to be imported from foreign particles automatic monitoring equipment, need to find an experienced agency sole agent import customs formalities, please call contact me, I will give you detailed answers import process, and agents throughout the clearance operation. -------------------------------------------------- ----------- particles automatic monitoring equipment import process mainly in the following four steps: 1. Imported equipment products provide the buyer with information, I import customs codes for you to find the instrument to determine the conditions of supervision. 2. regulatory conditions need to apply mechanical and electrical permits for O, AB need to apply for statutory inspection, confirm that the directory or directories within 3C 3. If you need to go outside 0 card, the purchase price of imported equipment is more than 1 million yuan also need to tender. 4. When ready to complete documents, goods to Hong Kong - for a single - customs clearance - contraband - release delivery domestic demand customs clearance instructions Customs clearance, Invoice, packing list, contracts, bills of lading. Request additional documents provided by the regulatory conditions. "Mechanical and electrical products import management approach Article XVIII": "subject to automatic import licensing imports of electromechanical products, the importer shall, before the customs declaration, the Ministry of Commerce or local, mechanical and electrical department to obtain a" People's Republic of China auto imports . "according to the provisions of the Customs clearance procedures" License "(hereinafter referred to as" automatic import license "), and who" automatic import license import clearance Consulting Contact: Mr. Mu Jiabin Tel: 15150494508 QQ: 965118923 Email: 965118923 @ qq.com circumnavigate coastal ports networking clearance: Shenzhen, Dongguan, Guangzhou, Qingdao, Tianjin, Chengdu, Shanghai, Kunshan, Ningbo, Xiamen --------------------- - PM2.5 monitoring instrument air purifiers efficiency detector, known as PM2.5 Instrument Description: CLH-2000-type air purifiers efficiency detector is designed to measure air purifier out of gas outlet unit volume of dust calculated based on the number of particles and the number of dust particles out of the air intake of the efficiency of the equipment. It is the foundation of the company's advanced high-sensitivity haltech miniature sensor technology developed on a set of aerodynamics, digital signal processing, optical and electrical integration of high technology products. The basic principle is the laser scattering by dust particles on the pulse signal output from the optical sensor for digital signal processing, measurement parameter settings, the results showed that key, time, date, etc. by the built-in microcomputer (MCU) to control and achieve . Which air purifier purification efficiency of the detector can simultaneously both size range (0.3,2.5) were detected and analyzed, before measuring instrument is set to the default, which is the case the user will get inside the instrument is measured at the inlet of dust per unit volume The number of particles displayed automatically after 20 seconds after setting the user at this time took the instrument to measure the outlet 20 seconds, automatically calculated after measuring the efficiency of the purification purifier which according to the number of particles of dust out of the air outlet of the current measurement . The test instrument has high precision, stable performance, versatility and strong, easy to operate, meet and exceed all performance of similar products. Its purification efficiency air purifier targeted testing, effectively reflects its purification effect. Users only need to use this instrument were air purifier inlet and outlet were measured, it can accurately reflect the number of real-time particulate matter before its purification, and calculate the percentage of its purification efficiency, therefore, this instrument is very useful for air purification purifier effectiveness analysis testing. Air purifiers detector efficiency is mainly imported from abroad with high sensitivity, high resolution, high stability and high precision sensor dust particle analysis is an important part of the pump through the pump to collect data, and then through the sensor detection and analysis and then analyze the data in real time to reflect on the LCD monitor.
