Can the QT40 test strip be used to test the Kay5 solution?

The QT40 test strip is specified to be a chlorine-based test strip, meaning it is expressly designed to measure chlorine levels in solutions. Using it for the Kay5 solution, which is not intended for chlorine testing, would not yield accurate or relevant results. Since the proper function of the QT40 is limited to monitoring chlorine concentrations, it cannot be effectively applied to the Kay5 solution. This reinforces the understanding of the specific applications and limitations of testing strips, emphasizing the importance of using the appropriate tool for the specific chemical or solution being assessed.
