Water sensing insights
How do conductivity sensor interface ASICs and self-developed circuits compare?
For R&D teams developing smart small home appliances such as water purifiers, water dispensers, coffee machines, smart water cups, and pet water fountains, this article compares the engineering differences and integration boundaries between AtomBit conductivity interface ASICs and self-developed circuits from dimensions such as development cycle, analog front end, verification, firmware, supply chain, and mass production maintenance.
Read Article →How the Water Detective 4 Supports Home Water Quality Screening
This article is intended for engineers, system integrators, and technical procurement specialists. It introduces the usage workflow, result interpretation, repeat measurement methods, and application boundaries of the Water Detective 4 portable multiparameter water quality tester in home water quality screening, helping readers determine when samples should be sent to a professional laboratory for testing.
Read Article →Water Detective 4: Why It's Not Just Another TDS Pen
Dealers are often asked by customers: "I already have a TDS pen, why should I buy Water Detective 4?" The answer isn't an extra screen, but the complementary matrix formed by nine screening parameters. This article starts from the measurement limits of TDS pens, breaks down the combined value of TOC, COD, UV254, TDS, EC, turbidity, hardness, salinity, and temperature, and provides actionable demo scripts, selection methods, field precautions, and validation approaches to help dealers reposition Water Detective 4 from "just another pen" to a portable rapid-screening workstation.
