VEDet-500Tcr Colorimetric Heavy Water Quality Online Analyzerr
On the basis of VEDet-500Cr6VEDet-500TCr colorimetric heavy metal water quality on-line analyzer is added with water sample digestion module and flow. Cr (Ⅲ) in water sample is converted to Cr (Ⅵ), and water sample Of the organic matter is also broken down into simple inorganic. Then the content of TCr in water samples was calculated according to the process of Cr (Ⅵ) measurement.
By supporting the installation of multi-stage filtration pretreatment of small cabinets, VEDet-500TCr colorimetric heavy metal water quality online analyzer can also be applied to water quality components of mixed water samples of Cr content monitoring, and even some of the inlet straight row of wastewater monitoring.
VEDet-500TCr colorimetric heavy metal water quality online analyzer is widely used in domestic electroplating, metallurgy, leather, printing and dyeing industries such as chromium pollution, while the major sewage treatment plant water treatment process control plays a processing effect to determine and monitor Important role.
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.
