RJY-B type dissolved oxygen colorimeterDetailed product description：

The RJY-B dissolved oxygen 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: Determination of dissolved oxygen content in water samples 1.0-2.0-3.0-4.0-5.0-6.0-7.0-8.0-9.0-10.0 mg/l
Test frequency: 90 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
First, rinse the sampling tube twice with pool water, then fill the sampling tube with pool water. Add 3 drops of reagent (I) and (II) to the tube in sequence, and immediately close the bottle stopper. Invert the bottle several times, let it stand for 3-5 minutes, open the bottle stopper, and add 3 drops of reagent (III). Cover the bottle stopper and shake it upside down until the precipitate is completely dissolved (if not completely dissolved, add 1-2 drops of reagent (III)). Use a pipette to take out part of the solution to the liquid level to the scale of the colorimetric tube, and then visually compare it with the standard color card from top to bottom. The color code with the same color tone is the dissolved oxygen content (mg/L). If observed with one eye color comparison, the effect is better.

Explanation: If the pool water is turbid, filter it before color comparison after the reaction is complete, and then compare it with the standard color card.
Packing list: 1 bottle each of dissolved oxygen reagents (I), (II), and (III), 1 test tube, 1 dropper, and 1 color chart.

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