The Extech RHT20 is a USB humidity and temperature datalogger that records relative humidity and temperature over time and connects directly to a computer for data analysis. An onboard LCD shows current readings, Min/Max values, and alarm status, while the USB connector plugs into a computer to download and review logged temperature and humidity data.

The RHT20 is built to monitor humidity and temperature levels in warehouses, storage rooms, freezers, shipping vans, and offices. Its USB connector plugs easily into a computer so logged temperature and humidity data can be analyzed after a monitoring run.
