Practical knowledge for better water-sensing decisions

Daily screening after tap water reaches the household: a decision framework

For smart water appliance product managers and hardware engineers, centered on the nine screening indicators of Water Detective 4, this builds a daily screening decision framework for tap water after it reaches the household, clarifying the boundary between screening and identification, sampling steps, result interpretation, interference factors and conditions for referral to the laboratory.

How to compare the inlet and outlet conductivity of a household water purifier

Why can't two isolated TDS readings be used to judge purifier performance? This article explains, from six aspects—measurement point location, time synchronization, temperature compensation, flow variation, probe installation, and data presentation—the correct design method for comparing inlet/outlet conductivity in household water purifiers, and introduces the application boundaries of the AtomBit BA022 dual-channel conductivity interface ASIC in RO, hydrogen water, and tap water equipment.
