The HDT-GFX-2 standalone USB data logger measures and stores up to 252,928 temperature and humidity readings over a -30°C to +80°C (-22°F to +176°F) and 0 to 100%RH range at a resolution of 0.1°C and 0.1%RH. Using the free EasyLog USB software (available for download using the link below) users can quickly set up the data logger and view downloaded data by connecting the device to the PC’s USB port using the supplied cable.

The data logger features a high-contrast graphic LCD and three-input buttons. This allows users to start, stop and restart the data logger using on-screen menus. This menu also provides real-time analysis of data either as a data summary (showing highest & lowest readings and alarm conditions) or as a graph that updates as new data is added. The Max and Min readings and also the Time and Date these are valid from, can be displayed on the LCD ( info button). If desired, the user can then reset the Max/Min shown on this screen of the LCD. Each time these maxima and minima are reset whilst logging, an "Event Marker" is created in the data. When the data has been downloaded to a PC these Events can be viewed on the graph (Mark Events), they also appear in the data file - associated with the corresponding log when the reset took place. For certain applications where procedures mandate that a regular physical check of the logger / stats have taken place – this can be useful as an audit / validation tool. Multiple data logging sessions can be stored on the device ready for upload to a PC at a later date.

The data logger’s robust design provides IP-67 waterproof protection and the two replaceable ½ AA batteries typically allow logging for up to one year.

The unit is supplied with a wall-mounting clip which also features two mounting holes and a magnet for quickly mounting the unit on a metallic surface.

1 This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH.

2 This specifies the overall error in the calculated dew point for relative humidity measurements between 40 and 100%RH at 25C.

3 At temperatures below -5C the LCD will exhibit slower response times. The LCD will be disabled at temperatures under -20C and above +70C.

4 At +25C and 10 minute logging rate, with no alarm LEDs or sounder and minimal LCD use.
