BOQU Instrument focus on development and production of water quality analyzers and sensors, including water quality meter, dissolved oxygen meter, pH sensors, etc.
The water quality multi-parameter is a new generation of water quality analyzer developed in response to some needs such as on-site or field operations. The multi-parameter water quality analyzer consists of multiple pulsed silicon light sources, cylindrical colorimetric bottles, a new optical system, a signal control amplification system, a microprocessor intelligent control, and an automatic display of analysis results, printing system, high-power lithium battery power supply system and corresponding Chemical kit composition.
You can choose to measure potassium, sodium, calcium, magnesium, chloride, sulfate, salinity, arsenic, mercury, hexavalent chromium, cadmium, lead, silver, cyanide, fluoride, iron, manganese, copper, Zinc, bicarbonate, carbonate and other components and parameters.
Precautions for using multi-parameter water quality analyzer:
1. The system is fully enclosed. The connection of the Karl Fischer reagent liquid path must be fastened, from the reagent bottle to the metering pump to the reaction tank, otherwise, the leakage of the reagent will directly affect the test results. Another problem with its non-sealing is that the Karl Fischer reagent absorbs air moisture during the test, which will delay the end of the titration.
2. The precise problem of water quality analyzer sampling. When calibrating the Karl Fischer reagent, it is necessary to take 10mg of water, and try to use a 10ul sampler, which is not only accurate and fast but also can avoid the adhesion of water drops. Similarly, the use of methanol reagents and ethyl esters also have similar problems. After the handling is completed, attention should be paid to shorten the time for opening the reaction tank as much as possible.
3. Adjust the magnetic stirring speed of the water quality analyzer. In the reverberation cell, since the titration reagent is added to the part and not in the same place with the electrode, the stirring speed should be as fast as it does not constitute turbulence so that the end can be reached as quickly as possible.
4. The titration speed setting of the water quality analyzer should be fast and then slow. The titration is fast at first to shorten the experiment time as much as possible, and the strain is slow towards the end, which can improve the accuracy of measurement.
Multi-parameter water quality analyzer moisture measurement technology uses new data communication skills and a new generation of moisture meters developed based on the control software of the computer operating system. It can adjust the titration accuracy and titration speed automatically according to the sample, which is convenient and fast. High-precision testing of moisture content of different scales; according to the environmental conditions of the experiment, automatic or manual drift value background deduction can be set to ensure that the analysis results are more accurate.
