StowAway
Relative Humidity Logger
The StowAway RH is a general purpose, durable, and reusable relative
humidity logger. Its sensor resists chemical corrosion by chlorine,
acetone, pentane, xylene, formaldehyde, ammonia, hospital germicides and
freon. Start the logger, readout and plot the data with BoxCar®
Pro for Windows or BoxCar
Pro for Macintosh software.

Calibration
The StowAway RH data loggers are individually calibrated at ten relative
humidities ranging from less than 10% to greater than 90%. This
calibration is stored in the logger. Due to the possibility of sensor
drift it is recommended that the RH loggers be factory calibrated
annually. For further information contact the company from which your
logger was purchased.
Temperature dependence
The StowAway RH sensor has a temperature dependence of 0.22% RH per
degree C. A ten degree C excursion from room temperature will add about
2% RH error.
