VEDet-500TAS Expelled Colorimetric Heavy Metal Water Quality Online Analyzer
VEDet-500TAs colorimetric method of heavy metal water quality online analyzer based on the new national standard silver salt colorimetric method, through the pre-reaction of hydrogen generated water samples of arsenic compounds in the full conversion of arsine gas, arsine gas is absorbed liquid And then reacted with the silver salt to form a compound having strong absorption in the characteristic wavelength band. The TAs content in the water sample is calculated by measuring the compound.
Liquid arsenic into gas-phase arsenic process, the majority of non-volatile substances in water samples and arsenic separation, greatly reducing the water sample measurement process of interference, thereby improving the measurement accuracy.
MDet-5000 TAs colorimetric heavy metal water quality online analyzer is widely used in industrial production process (sulfuric acid, resin, fertilizer, rare earth and other industries) in the total arsenic 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.
