[Scope of Use] This product is used to detect the concentration of "Disineer phthalaldehyde disinfectant".

[Usage] Immerse the color development block at the end of the test card completely in the solution to be tested (the liquid level should not exceed the dotted line position), take it out after three seconds, shake off the excess solution, place it horizontally for natural color development, and compare it with the standard color card for 2 minutes to read out the result.

Results labelling:

● Standard color A indicates: The concentration of the stock solution of phthalaldehyde disinfectant solution is 0.5%-0.6%, which is a qualified concentration;

● Standard color B indicates: The concentration of phthalaldehyde disinfectant solution is 0.3%-0.4%, which is an effective concentration. When the color developed is lighter than the standard color, it indicates that the concentration is lower than 0.3%, at this time, the solution should be replaced with new disinfectant solution.

● Standard color C indicates: The concentration of the stock solution of phthalaldehyde disinfectant solution is 0.1%-0.2%, which is a invalid concentration.
