USB Temperature-Humidity-GPP Data Logger with LCD

The #HT20 can log the ambient temperature and relative humidity (RH) of an environment for days, weeks or months. Included PC software can also calculate and log dew point and wet bulb temperatures, and absolute humidity levels in units of grains per pound (GPP) or g/kg. The #HT20 is ideal for water damage restoration and process control as well as environmental monitoring.
