Cómo hemos elaborado este informe
Twelve pH meters/testers verified 2026-08-12 directly against manufacturer product pages (Apera Instruments, Hanna Instruments, Bluelab, Milwaukee Instruments EU, Extech, Atlas Scientific) and, where manufacturer pages were unreachable or lacked full specs, corroborating current retail listings (Amazon) for Oakton, VIVOSUN, Hach, and YSI; two seed items could not be verified as real, currently-sold products — Dr.Meter's own site no longer lists a "PH100" (its pH-meter collection now shows only the "PH838" model, with no PH100 found on the manufacturer site, Amazon, or elsewhere) and HoneForest's Amazon catalog contains only a HoneForest-branded TDS/EC meter, no pH tester — so both were dropped and replaced with two verified, real, currently-sold pocket/portable pH meters (Atlas Scientific pH Kit KIT-101P and YSI pH100A) to keep the roster at 12 confirmed SKUs; fields left null (rather than guessed) wherever no fetched source stated that value, including Milwaukee MW102's US price (only its EU distributor price in EUR was found) and several Amazon-only listings (Oakton, Hach) whose spec sheets are not reproduced in the retail listing itself.
