Easy to use, high accuracy thermo-hygrometer (air humidity and temperature meter) with fast response time and data logging for up to 16,000 records. Powered by 1 x 9V battery or optional power adaptor
The backlit dual display can show relative humidity and temperature or dew point and temperature at the same time. The data logger can store up to 16,000 readings and the logging interval can be set to record data every 1 second up to every 59 minutes/59 seconds.
Install the free Windows software on a PC and connect to the data logger using the supplied USB cable. The software can retrieve historical logged data or perform real-time logging on-screen; data can be printed, graphed and exported in .csv, .txt or .ghf format (.ghf format for use only with the software). Exported files can be loaded into the software or other applications such as Microsoft® Excel.
An optional 1.5m probe extension cable
is available separately enabling readings to be taken up to 1.5 metres away from the hand-held unit. Unscrew the probe attached to the unit, connect it to the extension cable, and connect the extension cable back to the unit.
Supplied with carry case, instruction manual, 9V battery, software and PC USB cable.
