For how long should the RPC Ultra-Low Total Chlorine test strip be immersed in the sample?

The RPC Ultra-Low Total Chlorine test strip must be immersed in the sample for a full 60 seconds to ensure that it accurately measures the chlorine levels present in the water. Immersing the strip for this duration allows sufficient time for the chemical reactions on the test strip to occur, which are necessary for an accurate color development that indicates the concentration of total chlorine. Inadequate immersion time can lead to insufficient reactions and potentially erroneous results, undermining the effectiveness of the testing process. Therefore, adhering to the specified 60 seconds is critical for obtaining reliable results in chlorine testing.
