CEM DT-191B Temperature, Humidity & Air Pressure USB Datalogger

CEM DT-191B Temperature, Humidity & Air Pressure Datalogger

The CEM DT-191B belongs to the DT-191 series of Plug-PDF dataloggers. It monitors temperature, relative humidity and air pressure efficiently and conveniently over long periods: the readings are saved in the logger and simply read out by a PC through its USB interface.

Temperature is measured from -40 to 70 °C (-40 to 158 °F) with ±1 °C accuracy and 0.1 °C resolution, humidity from 0 to 100 %RH with ±3.5 %RH accuracy, and air pressure from 300 to 1200 hPa with ±3 hPa accuracy. The 40020-reading memory is shared as 13340 readings per channel, and the sample rate is freely selectable from 1 minute to 24 hours.

Plugged into a USB port, the logger works like a USB flash disk and delivers a PDF report immediately, while the analysis software (Windows XP/Vista/win7/win8/win10) displays the logged data as graphs.
