Introduction
Congratulations on your purchase of the Relative Humidity and Temperature Datalogger. This
datalogger measures and stores up to 16,000 relative humidity and 16,000 temperature readings
over 0 to 100%RH and ‐40 to +70°C (‐40 to +158°F) measurement ranges. The user can easily
configure the logging rate, high/low alarm and start‐mode, and download the stored data by
plugging the module into a PC's USB port and running the supplied PC software. Relative Humidity,
Temperature and Dew Point data can then be graphed, printed and exported to other applications.
GPP (grains per pound) data can be viewed using the optional RHT10‐SW software. The data logger
is supplied with a long‐life lithium battery, which can typically allow logging for one year. This meter
is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
