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 set up 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. 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
