T8000-Ni on-line monitoring instrument for nickel in water is an instrument produced by Hangzhou Modi to monitor nickel content in water. This chapter mainly introduces the measuring method of the instrument. It can be divided into the following 4 types:

· Timing measurement can be realized every day in any user want to monitor the time to start the instrument for measurement;

· Isochronous measurement can automatically start the instrument for measurement every few hours at a fixed time interval every day;

· Continuous measurement can realize automatic sample measurement one by one, which can be used for product acceptance and related technical certification;

· Manual measurement can realize the user to start the measurement at any time, and can be used for field experiment comparison and equipment installation and debugging.

In addition, let’s talk about the working principle of the instrument:

The pre-treated water sample is injected into a special reactor by the injection pump to react with strong acidic reagents. All forms of nickel in the solution are present as divalent nickel ions, and then the masking agent is added after neutralizing the excess acid to eliminate the interference of coexistence ions. Then the oxidizing agent is added to oxidize all forms of nickel in the water sample to trivalent nickel, and then the characteristic color developing agent is added for color developing reaction. In the measuring range, the degree of gas color change is proportional to the total nickel concentration in the water sample, and the nickel content in the water sample can be calculated by measuring the change in color.
