Giải thích
The only reliable way to confirm sanitizer concentration is to measure it with the test kit made for that specific sanitizer, chlorine, quat, or iodine, and document the reading. Smell, color, and trust are not measurements and can be badly wrong. Routine testing and recording is part of active managerial control over warewashing.
