SH-B type hydrogen sulfide colorimeterDetailed product description：

The SH-B hydrogen sulfide 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 sulfides in water samples at 0.05-0.10-0.15-0.20-0.25-0.30 mg/l
Test frequency: 80 times/box

Characteristics of SH-B type hydrogen sulfide colorimeter
☆ 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 a water sample, then take the water sample to the scale line of the tube. Add 7 drops of hydrogen sulfide test solution to the tube and gently invert it once (only once). After 10-15 minutes, visually compare the color with the standard color card from top to bottom. The color code with the same color tone is the content of hydrogen sulfide in the water sample (measured in milligrams per liter of sulfur). If observed with one eye color comparison, the effect is better.

Explanation: If the water sample is turbid, a few drops of dilute alkali can be added first, filtered, and then tested according to the above method.

Packing list: 2 bottles of hydrogen sulfide reagent, 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.
