KHM100 On - line Automatic Heavy Metal Water Quality Monitor

Product Details

This automatic monitor uses anodic stripping voltammetry for real - time on - line monitoring. The main components of the monitor include: reagent storage unit, metering unit, digestion unit, detection unit, display and recording unit, data processing and transmission unit, etc. Through automatic control of sampling, the water sample to be tested and the digestion agent are automatically added to the digestion cell through a multi - position valve. The temperature and time are controlled to carry out a constant - temperature digestion reaction. Then, the digested solution and the electrolyte solution are added to the electrolytic cell by an injection pump. Using a three - electrode system, the enrichment, standing and stripping processes of cadmium in the water sample to be tested are carried out by changing the potential on the working electrode, and the signal values during the stripping process are recorded. Combined with calibration information collection, the concentrations of heavy metals (cadmium, lead, copper, zinc, arsenic) in the water sample are calculated.

Product Advantages

(1) It has a low detection limit and lower limit of quantitation, meeting the ppb - level detection requirements and leading among similar products in the market.

(2) The product has multiple patented structural designs. It has a small dead volume and strong anti - bubble interference ability, not only meeting the needs of on - line monitoring but also being applicable to electrochemical kinetics analysis research.

(3) The unique electrode cleaning technology of the product can eliminate the memory effect problem caused by electrode enrichment residues.

(4) The product has a moderate volume, facilitating the integration and application of various systems. It is easy to install and simple to maintain.

(5) It is equipped with an on - line digestion device, which can eliminate the interference of organic matter on the determination.

(6) It has intelligent fault diagnosis, with functions such as liquid - shortage judgment and reagent - remaining - amount early warning.

(7) The product has the extended function of simultaneously measuring multiple parameter factors with one device.

(8) It has multiple functions such as standard sample verification, zero - point verification, span verification, single - point calibration and multi - point calibration, suitable for different application scenarios.

Main Applications

It is widely used in water quality monitoring of pollution sources such as municipal sewage, mining industry, electroplating industry, surface water such as rivers, reservoirs, lakes, landscape water, groundwater, domestic drinking water, seawater, etc.
