Following the WAOL 2000-Cr6 + water quality online analyzer-hexavalent chromium, Tianrui Instruments once again launched the WAOL2000-TCu water quality online analyzer-total copper, and WAOL2000-TNi water quality online analyzer-total nickel two series of products. R & D background: The launch of the "WAOL 2000 Water Quality Heavy Metal Online Monitoring Series" based on the "Twelfth Five-Year" heavy metal plan is based on the careful study of relevant national policies and market needs.

In February 2011, the state passed the "Twelfth Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution", which plans to invest 75 billion yuan in five years to build a relatively complete heavy metal pollution prevention system. The heavy metal pollutants under key prevention and control are divided into two categories: the first category: lead, mercury, cadmium, chromium, arsenic; the second category: thallium, manganese, bismuth, nickel, zinc, tin, copper, molybdenum and so on.

At the same time, the "Twelfth Five-Year Plan" also included the construction of drinking water safety as a key task, and plans to solve the drinking water safety problem through measures such as increased capital investment, improved infrastructure, and increased supervision.

The WAOL 2000 series can effectively meet the requirements of online monitoring of heavy metals in pollution sources (paper, steel, pharmaceuticals, petrochemicals, electroplating, leather, metallurgy, printing and dyeing, etc.) and municipal sewage, and the test results can fully meet the relevant requirements. Policy and standard requirements.

WAOL2000-TCu water quality online analyzer-the total copper detection results can fully meet the national standards and standards such as HJ486-2009 "Determination of Copper in Water Quality 2,9-Dimethyl-1,10 Phenanthroline Spectrophotometry"; WAOL2000 -Tni water quality online analyzer-The total nickel detection results can fully meet the national standards and standards such as HJ11910-89 "Determination of Nickel in Water Quality, Dimethylglyoxime Spectrophotometry". Technology Overcoming: Effectively Solve the Problems of Current Users

Low stability, large amount of maintenance, and high failure rate are some of the major problems that plague users in the current "online monitoring series of products." Tianrui Instrument's "WAOL2000 Series Water Quality Online Heavy Metal Analyzer" adopts advanced software and hardware design, and has effectively overcome the above difficulties through 10 months of investigation and research and development.

The test level of WAOL2000-TCu and WAOL2000-TNi is in the leading position in China, with an accuracy of up to 2%. The instrument is based on the principle of colorimetric detection, adopts the AC modulation detection circuit and filter algorithm independently developed by Tianrui, and introduces a high-precision injection pump, which effectively improves the accuracy and stability of the instrument.

WAOL2000-TCu and WAOL2000-TNi are also equipped with a fully automatic high-precision dilution device, which greatly expands the linear range of the instrument. The effective measuring range of the instrument is 0.05 ~ 5mg / L. It can store more than one year of operating data.

Humanized and intelligent system design is another major feature of the instrument. All functions of the instrument can be completed on the touch screen interface, and can also be remotely controlled. Automatic pump sampling, automatic calibration, automatic alarm, automatic storage and other functions make the instrument very bright. Customer trial: 720 hours of stable operation

In order to further ensure the finishing and inspection performance of WAOL2000-TCu and WAOL2000-TNi, Tianrui Instruments repeatedly self-inspected the products. And invite heavy metal water quality monitoring units to try. At present, the results of laboratory testing and customer trial feedback are good.

Tianrui conducted strict feedback tests on the successfully developed WAOL2000-TCu and WAOL2000-TNi. Test items include: precision, accuracy, linearity, zero drift, range drift, detection limit, long-term stability, average trouble-free operating time, voltage stability, analysis time, instrument abnormality testing, etc. The test results of various indicators are good.

The actual water sample comparison test further verified the accuracy of the instrument. The R & D team specially collected water samples from the city's electroplating management center and brought them back to the laboratory for comparison testing with multiple instruments. Repeated test results show that: WAOL2000-TNi's test results for total nickel in water samples are basically consistent with AAS6000 atomic absorption spectrophotometer; WAOL2000-TCu's test results for total copper content in water samples are consistent with spectrophotometer.

The trial results of the Kunshan Electroplating Management Center further confirmed the performance of the WAOL2000 series. The instrument runs continuously for 720 hours without failure. The test process truly reflects the heavy metal content in the sewage discharged by a metal manufacturing company in Kunshan. The daily test data is consistent with the manual comparison data on site.
