Extech MO220 Wood Moisture Meter can take measurements using the integral pin electrodes (replaceable pins) or a heavy duty remote probe (included) with an automatic temperature compensated (ATC) readings when used with the temperature probe.

This Humidity and Temperature USB 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. Data stored on the Humidity and Temperature USB Datalogger can be downloaded 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. An optional RHT10-SW software has been added to this humidity and temperature USB datalogger which will allow you to view the GPP (grains per pound) data. The data logger is supplied with a long-life lithium battery, which can typically allow logging for one year. Extech RHT10 Humidity and Temperature USB Datalogger is shipped fully tested and calibrated.
