The Extech RHT10 is a compact, standalone USB datalogger that records up to 16,000 readings each for relative humidity (0 to 100% RH) and temperature (–40 to 158°F / –40 to 70°C). Designed for long-term environmental monitoring in warehouses, cold storage, shipping containers, laboratories, and water damage restoration sites, it features a user-selectable sampling interval from 2 seconds to 24 hours and a battery life of approximately one year. Data is easily downloaded via built-in USB to a Windows® PC using the included software, which displays dew point and allows for detailed analysis. An optional RHT10-SW software package enables calculation of absolute humidity in Grains per Pound (GPP) or grams per kilogram (g/kg).
