Our company promises:Complete the production tasks of the supplied products with quality, quantity, and on time, and transport the products to the customer's demand site in a timely manner to ensure normal operation.

Whole process monitoring:Customers only need one phone call, and the after-sales service department adopts a one-stop mode, comprehensive responsibility system, full monitoring and implementation, and tracking of processing results to ensure customer satisfaction.

Principle:

In acidic solution, trivalent chromium is oxidized to hexavalent chromium, and potassium peroxide is used to oxidize the digestion solution and water sample

Under high temperature and pressure, various nitrogen-containing compounds in water samples undergo potassium oxidation and digestion to transform into

Salt. Under acidic conditions, salt reacts with a color developer to form a complex, which varies with the depth of the color in the sample

The nitrogen content is directly proportional to the total nitrogen content in the sample.

Features:

Select valve components: Choose reagent sampling timing, flexible and diverse channels, versatile functions, and have the smallest dead volume,

Advantages such as easy maintenance and high lifespan.

It has printing function and can be connected to a printer (optional) to print the measured data in a timely manner.

Adopting a 7-inch touch screen and a simple operating interface, it can be easy for users to learn, operate, and maintain.

The ultra large data storage capacity enables the preservation of historical data for no less than 5 years (with a measurement interval of 1 time/1 hour),

Greatly meeting the needs of customers.

Automatic liquid leakage alarm function, when a reagent leakage occurs, the instrument will automatically alarm and prompt the user to perform maintenance.

The use of optical signal recognition function ensures high accuracy in quantitative analysis.

The maintenance of chemical reagents is simplified and convenient, with a monthly replacement of reagents, greatly reducing the maintenance workload for users.

One click upgrade of USB flash drive makes software updates easier.
