What is the ideal PPM for reading test strips for QSAN?

The ideal parts per million (PPM) range for reading test strips for QSAN is 150-400 PPM. This range is significant because it reflects the effective concentration of chlorine residual in water, which is critical for water quality assurance and sanitization processes.

Maintaining chlorine levels within this range ensures that the water remains safe for use while also being effective in killing bacteria and other pathogens. Water with a PPM too low may not effectively disinfect, while water with a PPM too high can lead to irritation or adverse chemical reactions. Therefore, the 150-400 PPM range strikes a balance that is essential for both safety and efficacy in a variety of situations, such as food service or sanitation environments.

Understanding these PPM levels is vital for those managing water sanitation processes, as they need to ensure compliance with health and safety standards.
