THE PUBLICATION

Commercial disclosure

The relationship should be as visible as the link.

Who owns this site, and what else do they own?

WaterMeasure is operated by RETRETO NEXT LIMITED. Company No. 15166864, registered in England and Wales. Registered office: Office 8929, 182-184 High Street North, East Ham, London E6 2JA. Companies House record. The operator also owns instrument retail websites. The publication operates alongside those retail businesses and does not claim financial independence from the instrument trade.

Which related shops may be linked from a nutrient note?

Nutrient notes may link hmdigitalp.co.uk — a commercially related retail site — and smartquali.co.uk — a commercially related retail site. Those links sit next to this relationship on the pages that use them. A shop catalogue is not a measurement and is not a checked handbook.

Which related shops stay on this page only?

The same operator is associated with other instrument shops. They are listed here so the relationship is visible. This edition publishes no performance pages for them, and they are not used as instrument evidence in the nutrient notes. Those names are listed as plain text.

They are commercially related shops, not independent evidence.

What do outbound links support, and what do they not imply?

Links to WHO and DWI documents, manufacturer documentation and external hydroponic publications support the explanation. They do not imply that those organisations endorse this site. These pages contain no paid placements or product purchase links except the commercially related shop links identified above.

What would a later instrument test have to disclose?

No original instrument test is claimed on these pages. A page that reports one must identify how the sample was obtained, whether it was retained, and any compensation or editorial arrangement. A supplied sample cannot establish the performance of every unit.

What will this publication not claim for payment?

A drinking-water result is not a product sold here, and owning a product does not stand in for evidence. No paid or commercial arrangement justifies fabricated measurements, ratings or reviewer credentials. If an affiliate link is added, it will state that a commission may be earned.
