What it does
Enter temperature and relative humidity to understand dew point, wet bulb, grains per pound, absolute humidity, condensation risk, comfort, mold conditions, room targets, and preservation ranges. Log rooms over time, compare readings, and export reports without an account or internet connection.
PRO MOISTURE ACTION PLAN The new Moisture Action Plan turns readings into a prioritized dry-out plan. Add indoor temperature/RH, coldest surface temperature, outdoor air, room volume, target humidity, tightness, and air-change goal. Dewpoint Rooms calculates:
PRO FIELD BOARDS Twelve high-resolution offline field boards cover basement dry-out, window condensation, crawlspaces, HVAC latent load, wood movement, cellar preservation, bath/kitchen exhaust, concrete cure, grow-room VPD, bedroom comfort, heat safety, and client reporting.
AIR SWAP Relative humidity alone cannot tell you whether opening a window will help. Air Swap compares indoor and outdoor moisture mass in grains per pound, calculates outdoor dew point, estimates the relative humidity of that air after it reaches the indoor temperature, and gives a clear ventilation verdict.
