Heavy Metal Online Monitoring Instrument
Total Nickel Online Monitor
product details

Product Model: T8000-Ni

 

System Overview

 

The pre-treated water sample is injected into a special reactor by the injection pump to react with strong acidic reagents, so that all forms of nickel in the solution are present as divalent nickel ions, and then neutralize the excess acid and add masking agent to eliminate the interference of coexistence ions, and then add oxidizing agent to uniformly oxidize all forms of nickel in the water sample to trivalent nickel, and finally add characteristic color developer for color 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.

 

Measurement Method

 

Acid oxidation and optical colorimetric determination have wider applicability and accuracy than selective electrode method and anodic stripping voltammetry.

Multiple Options Are Available

Timing measurement enables the instrument to be started every day at any time the user wants to monitor;

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.

System Characteristics

 

· The pretreatment device has the function of self-maintenance, thus reducing the maintenance workload of users.

· The chemical reaction time can be adjusted, the determination process and results meet the relevant standards;

· The adjustable quantitative sampling device ensures that the instrument is prepared to measure various water samples by adjusting the reagent dosage and sampling amount;

· The use of non-contact injection pump to avoid direct corrosion of reagent reagent pump, which can extend the life of core components and reduce user cost;

· All imported components, analytical flow path design and reagent formulation ensure measurement reproducibility, which can reach 5% at present.

· Automatic operation, no personnel on duty, can achieve automatic zero, automatic calibration, automatic measurement, automatic cleaning, automatic maintenance, automatic protection, automatic recovery and other intelligent functions;

· On-line monitoring methods are diversified, which can realize manual measurement at any time, automatic timing measurement, automatic cycle measurement and other measurement methods;

· Automatic leakage alarm function, when there is a reagent leak, the instrument automatically alarms, prompting the user to maintain.
