VEDet-500TMn Colorimetric Heavy Metal Water Quality Online Analyzer

Product Description

VEDet-500TMn colorimetric heavy water quality on-line analyzer based on “HJ / T344-2007” water quality of the total manganese measurement of the national standard method. In alkaline medium, Mn (Ⅱ) in water sample is oxidized to Mn (Ⅳ) and Mn (Ⅳ) forms brown compound with formaldehyde oxime. The color of this compound is proportional to the content of manganese in water sample. The internal colorimetric module measures the absorbance of the compound to calculate the manganese content of the water sample.
VEDet-500TMn colorimetric heavy metal water quality on-line analyzer is widely used in industrial wastewater treatment plants in total manganese monitoring, industrial production processes (mining, metallurgy, rare earth industry) in the total manganese monitoring occasions.

Product Features

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.
