Currently automatic monitoring instruments 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 into use for the import of equipment. To reach the qualifying level, and running continuity, stability dominated all aspects of the product, only the imported products to meet. If your company needs to import foreign particulate matter from automatic monitoring equipment, the need to find an experienced agency sole agent import customs formalities, you are welcome to call to contact me, I will give you detailed answers import process, and agents throughout the clearance operation. -------------------------------------------------- ----------- particulate monitoring instruments automatically import process mainly in the following four steps: 1. provide the buyer with equipment imported product information, I import customs codes for you to find the instrument to determine the conditions of supervision. 2. The regulatory conditions need to apply mechanical and electrical permits for O, AB need to apply for statutory inspection, make sure that the directory or directories within 3C outside 3. If you need to apply for 0 card, the purchase price of imported equipment more than 1 million yuan also need to be tender. 4. When ready to complete the documents, goods to Hong Kong - for a single - customs clearance - contraband - release delivery of domestic power of attorney must provide clearance of customs clearance, Invoice, packing list, contracts, bills of lading. Plus regulatory conditions require the documents provided. "Electromechanical products import management approach Article XVIII": "subject to automatic import licensing imports of electromechanical products, import entity shall, before the customs declaration, the Ministry of Commerce or the local and departmental mechanical and electronic offices to obtain a" People's Republic of China auto imports . "according to the customs clearance procedures prescribed" 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 efficiency of the instrument. It is the foundation haltech company's advanced high-sensitivity miniature sensor technology set out on a self-developed aerodynamics, digital signal processing, optical and electrical integration of high technology products. The basic principle is 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) 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 unit volume measured at the inlet dust The number of particles displayed automatically after 20 seconds after setting, users at this time took the instrument to measure the outlet 20 seconds, the measurement is automatically calculated after purification efficiency paragraph cleaner dust according to the number of particles out of the air outlet of the current measurement . The instrument has tested high precision, stable performance, versatility and strong, easy to operate, meet and exceed all the performance indicators of similar products. Its purification efficiency of the 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 before and after their purification of particulate matter, and calculate the percentage of its purification efficiency, therefore, this instrument is very useful for air purification is purifying effect analysis and detection. Air purifiers efficiency detector is mainly imported from abroad high sensitivity, high resolution, high stability and high accuracy 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.
