Extech RHT30 USB Humidity/Temperature Datalogger Details

Place this instrument in your office, greenhouse, warehouse, van or any other environmentally-controlled environment to constantly log temperature/humidity levels over a period of time.

Suitable for either being propped on a surface or wall-mounted, the Extech RHT30 is easy to place wherever you need it. It's also fully configurable - the user can set the language, the sampling rate (the rate at which the meter logs data), set delayed logging and alarms, set high/low alarm limits and also set a password to prevent tampering with the RHT30's settings.

Once configured, the RHT30 can simply be left and it will log data at the rate specified for as long as you want (battery life is approx 3 months). Up to 48,000 temperature/humidity readings can be logged in the unit's internal memory; if this is filled, the unit will stop logging or you can manually stop the process by pressing the stop button on the RHT30.

When you're done logging, simply insert the RHT30 into your PC using the built-in USB connector. The data can then be downloaded as a PDF report or imported directly into Excel complete with a trending graph, ready for further analysis.
