Extech RHT20 Humidity and Temperature Datalogger

Extech RHT20 Humidity and Temperature Datalogger

A moisture meter tells you how wet things are today. The RHT20 tells you what happened after you left. Leave it on site and it records humidity and temperature, then hands the data to your PC over USB.

Set it and leave it

It stores 16,000 humidity and 16,000 temperature readings, at any interval from one second to 24 hours. The battery lasts about three months.

Check it at a glance

The screen shows the current readings, the min and max, and whether an alarm has been triggered, so you can check a room on your next visit without plugging anything in.

Proof for the report

The included Windows software shows the readings as a graph and works out dew point, which gives you a clear record of how a space dried out or how conditions changed.
