NI-B Type Nickel ColorimeterDetailed product description：

The NI-B nickel colorimeter fully embodies the foundation of rapid analysis. Whether using visual colorimetry or titration, reliable results can be obtained quickly. It is like a portable laboratory that can perform routine water quality testing in real time, which can significantly save time and costs.

Test scope: Determine the concentration of nickel ions in water samples at 0.05-0.10-0.25-0.50-0.75-0.0-1.5-2.0 mg/l
Test frequency: 50 times/box

Product Features
☆ Measured by visual colorimetry or titration, easy to operate.
It takes 2-10 minutes to complete the analysis of a water sample, which is fast and efficient.
The measurement results are reliable.
All reagents and accessories are built-in and do not require additional preparation.
☆ Low analysis cost.
☆ Small size, light weight, easy to carry.
☆ Suitable for real-time on-site water quality testing of sea and fresh water.

Operation Method
Colorimetric method
Rinse the colorimetric tube twice with pool water, then take a water sample to the scale line, add 4 drops of nickel reagent (I) to the tube, shake well, add 7 drops of nickel reagent (II) and shake until the solution yellow disappears, then add 7 drops of nickel reagent (III) and shake well. After 10 minutes, visually compare the color with the standard color card from top to bottom. The color code that is similar to the color tone of the solution in the tube is the nickel content in the water sample (mg/L). If observed with one eye color comparison, the effect is better.

Instructions:
If the pool water is turbid, take a sample and let it stand for a few minutes. After the water sample is clear, take the upper clear liquid for testing.
Reagent (I) should be stored away from light and immediately returned to the box after use.
Packing list: 1 bottle each of nickel reagents (I), (II), and (III), 1 test tube, 1 dropper, and 1 color chart.

Note:
Some indicators may have special operational requirements, please read the instructions on the back of the color chart carefully before use.
