Japanese DKK analyzer HDM-135A/5605

DKK analyzerTypical applications: online monitoring of total copper in surface water, industrial wastewater (such as electroplating wastewater), and sewage plant inlet and outlet; Instrument features: low waste liquid. The amount of waste liquid is only 1.4L/month; Low reagent consumption. No need to replace reagents for a month. Automatic range, automatic dilution. It has both low range and high range modes. Built in high-temperature digestion device; Automatic backwash sample filter, automatically cleaned after each test; Automatic calibration. The instrument uses high-temperature digestion of water samples to convert complex copper, organic copper, etc. in the water sample into divalent copper ions. The DKK analyzer converts divalent copper to cuprous through the reducing agent hydroxylamine hydrochloride, and uses cuprous sulfate as a chromogenic reagent. The cuprous ions react with cuprous sulfate to form a yellow brown complex. The concentration of the complex is positively correlated with the total copper concentration in the water sample. Perform spectrophotometric measurement at a wavelength of 470nm. The DKK analyzer analyzes the concentration of the sample by comparing the difference between the initial color of the sample and the color after adding a color developer.

DKK analyzerThe instrument/system consists of a variable frequency power transmitter with digital output and a secondary instrument with digital input, which are connected through optical fibers. *Avoiding attenuation and interference in transmission links in complex electromagnetic environments. The lowest accuracy index measured under various test conditions of electrical products such as motors, frequency converters, transformers, and energy-saving lamps is used as the nominal accuracy index. According to the range of voltage and current from 1mV to 20kV, 100uA to 7000A, there are more than 100 specifications and models of variable frequency power transmitters to choose from. For high voltage and high current measurement, low voltage and low current transmitters can be used in conjunction with external sensors. DKK analyzer can also directly use high voltage and high current variable frequency power transmitters for measurement, reducing intermediate links and improving system measurement accuracy. Each analyzer can be configured with 1-6 power units (variable frequency power transmitters). For testing projects with more power units, multiple analyzers can be cascaded to achieve accurate synchronous measurement between multiple analyzers under the control of synchronous optical fibers.

DKK analyzerBy applying analytical instruments, we can achieve improvements in industrial technology, efficiency, quality assurance, and cost reduction. Therefore, it can be said that users are not just consumers, but more importantly, they are beneficiaries. Therefore, accelerating the development and promotion of application technology, and maximizing the actual use effect of analytical instruments, is an important task that analytical instrument manufacturing enterprises need to accomplish. Due to the powerful network and communication capabilities, remote maintenance also makes the provision of this service simple and easy. At the same time, with the increasing demand for precision, performance, and stability of analytical instruments and systems, as well as industrial process analysis systems in downstream industries, DKK analyzers will utilize * technology and processes to select appropriate analyzers, application software, circuits, and gas paths, promoting the development of analyzer systems towards low power consumption, multifunctionality, integration, and systematization, which will be the industry's development trend.
