After mixing the water sample with the regulator, the nickel ion reacts with the indicator in the presence of the ammonia environment and the indicator to form a colored complex. The analyzer detects the color change, and converts the change into nickel ion value and outputs it. The amount of colored complex is equal to that of nickel ions.

Characteristics:

l Valve components selection. It can select the reagent sampling sequence, with flexible channels, variable functions, minimum dead volume, easy maintenance, long service life and other advantages.

l Printing function. It can be connected to a printer (optional order) to print the measured data in time.

l It adopts 7-inch touch screen, with simple operation interface, easy for users to learn, operate, and maintain.

l Super large data storage capacity. It can realize storage of historical data for no less than 5 years (measurement interval is 1 time/1h), which greatly meets the needs of customers.

l Automatic leakage alarm function. When reagent leakage occurs, the instrument will automatically alarm to remind the user to perform maintenance.

l Light signal recognition function to ensure high accuracy of quantification.

l Simple and convenient chemical reagents maintenance. The reagents can be replaced once a month, which greatly reduces the maintenance of the user.

l U disk one-click upgrade. The software update is much easier.
