Model RHT50

Introduction

Congratulations on your purchase of the Relative Humidity / Temperature / Pressure Datalogger. This datalogger
measures and stores up to 10,000 readings. 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. Data can then be graphed, printed and exported to other applications. The data logger is supplied
