THE PUBLICATION
About WaterMeasure
A publication about what a nutrient pH or EC reading can establish.
What does WaterMeasure explain?
WaterMeasure publishes UK English notes on pH and electrical conductivity in horticultural nutrient solutions. The notes are for growers who keep a reservoir log and want the quantities kept apart. These pages are source-based explanations. External authors’ measurements were not performed for this publication. WaterMeasure is not a drinking-water laboratory, a certification body or an accredited calibration laboratory.
- pH, EC, the TDS factor, ATC and immersion, each in its own note
- Three blank CSV records, with headings and one empty row
- A commercial disclosure for the related retail shops

We link original hydroponic publications, manufacturer documentation and official UK and WHO documents, and the different role of each source stays visible. The methods page sets out what is still required before a result can be called an original test.
