SRT LogDashboardDaily EntryHistoryTrendsExport to Excel
A demo with made-up data for a made-up plant: every reading and result is generated. Look around, or enter today's readings; it all resets each night. Back to jmco.app

History

Every saved day, newest first. Results are worked out from the readings with one set of formulas, so every year compares fairly. RAS is each clarifier's reading in mg/L; a dash means it wasn't taken. Open a day to see or change it.
