The \u003cspan\u003eDewGuard\u003c\/span\u003e goes three readings deeper: ambient humidity (0–100%, ±3.0%), wet bulb temperature, and dew point down to -50°C. That last number is the one HVAC technicians and spray foam installers argue about on job sites. Dew point tells you the exact air temperature at which moisture will condense onto a surface, and condensation is where mold starts, coatings fail, and ductwork corrodes. Relative humidity alone won't give you that threshold. Dew point will.\u003c\/p\u003e\n\u003cdiv id=\"sah19-table-wrapper\"\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px; -webkit-overflow-scrolling: touch;\"\u003e\n\u003ctable style=\"width: 100%;
