This document introduces the usage and features of the RHT50 RHT50 V2.1 Humidity + Temperature + Pressure Datalogger. This datalogger can measure and store 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 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.
The EXTECH RHT50 is a humidity, temperature, and pressure datalogger capable of storing up to 10,000 readings. It features selectable data sampling rates from one minute to 18 hours, manual or automatic start modes, and user-programmable alarm thresholds. The device includes status indication via Red/Yellow and Green LEDs and connects to a PC via USB for setup and data download.
