VDet-500Tni Colorimetric Heavy Metal Water Quality Online Analyzer
VEDet-500TNi colorimetric heavy water quality on-line analyzer based on “GB 11910-89” total nickel water quality measurement of the national standard method. The nickel-containing compounds in the water sample were decomposed into nickel ions by using the persulfate salt under high-temperature confined conditions. In the alkaline medium, the nickel ions reacted with the diketoxime to form compounds having strong absorption at the characteristic wavelength. The TNi content in the water sample was calculated by measuring the compound.
VEDet-500TNi colorimetric heavy metal water quality on-line analyzer is widely used in industrial production processes (electroplating, batteries and other industries) in the total nickel monitoring occasions.
High reliability, low maintenance
The key components are imported parts, high reliability, long life, suitable for long-term on-line monitoring;
Metering module using photoelectric measurement method, the detector is not in direct contact with the liquid, does not appear irresolute situation.
Flow through a special design, not easy to plug.
Mature technical means to ensure high accuracy
Photoelectric measurement using a special measurement algorithm, making the injection is accurate, small sample error.Unique bubble mixing technology to ensure that the continuous injection, the sample and reagent fully mixed. Automatic chroma, turbidity compensation algorithm, taking full account of the actual situation of water samples, the monitoring results are true and reliable.
Patented circular multi-channel dilution sampling technology to achieve a large range of ratio expansion.
A variety of practical functions, to provide user-friendly operation.
Automatic leakage alarm function, when a reagent leak, the instrument self-test alarm, prompting the user for maintenance.
Abnormal state of automatic processing, when the operation occurred during the abnormal power-down until the next restoration of power supply, the instrument will self-diagnosis of abnormal state, and restore the flow channel to wait for the state to do the sample.
Instrument operation is simple, full touch screen control panel and friendly software interface, providing a wealth of information tips, software, easy to understand With multi-level management authority to set the password and the screen digital lock, to prevent misuse of others.
