Help: Water quality · 3 min read # Record readings and see them against your limits How readings work in AquaOps: recording them on a system or visit, how bands judge them, and where the company-wide quality list is. By the AquaOps team *[Image: A round clarifier tank with green-tinted water and a steel walkway at a small water treatment plant]* A reading is a measured value (for example TDS, pressure or pH) recorded against a system. AquaOps judges it against bands set for your company and shows the result as a word and a colour. ## Record a reading Technicians record readings during a visit on the phone, with or without signal. Staff can also add a reading from the system’s page. Always choose the right parameter and unit. ## How bands work For each parameter and type of system your company defines limits for excellent, good, fair and poor. A new reading takes its band at once. A company-wide view, **Water quality** in the menu, lists every system with its worst current reading and can be filtered by client and site. ## Using the trend Open a system to see its readings over time. A reading that creeps towards fair is a reason to book a visit.
