Temperature Data Logger with Graphic LCD Screen

Product Code: HDT-GFX-1

The HDT-GFX-1 standalone USB data logger measures and stores over 250,000 temperature readings over a -30°C to +80°C (-22°F to +176°F) range and at a resolution of 0.1°C. 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 which 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 and lowest readings and alarm conditions) or as a graph that updates as new data is added. 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.
