3 Overview

Nitrate Diver automatic continuous monitoring of groundwater, surface water, sewage and industrial waste water and other water bodies The nitrate concentrations. Nitrate Diver measurement method and the main electrode. Spectrophotometry by measuring a specific wavelength The absorbance of water samples quantitative determination of nitrate nitrogen content; electrode is obtained nitrate in water samples by measuring the electrode potential Acid nitrogen content. Instrument consists of sampling, processing water samples, testing, data acquisition, processing, display and transmission unit. Technical information and test prototype to be submitted by the applicant 4 Technical data submitted 4.1 Technical submissions include. a) prototype photos; b) product standards (including test methods); c) assembly diagram, schematic diagram and major components; d) Instructions; e) manufacturing unit or technical test report done by institutions. 4.2 provides experimental prototype 4.2.1 The applicant shall provide own production prototype. The applicant can apply for a single product to be Press products apply. Where the application as a single product, under normal circumstances should provide two prototypes. Press products Application to extract a third of a representative of each series of product specifications of products; each specification provides test prototype Number, according to the principle of a single product application execution; according to the above principles, too much the number of prototypes can be appropriate to reduce the number of prototypes the amount. Representative specifications, acceptance of the application by the government administrative departments and agencies have undertaken trials on the application of technology ......
