Sensor recovery verification after aquaculture equipment cleaning

A practical field guide for commercial fish farming and aquaculture: use the Water Detective 4 portable multi-parameter test pen to quickly screen rinse water after cleaning and determine whether sensor readings have returned to the operational baseline; clarify the boundary between screening and laboratory identification.

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.
