Product Description

EL-GFX-2

Temperature and Relative Humidity Data Logger with Graphic LCD Screen

The EL-GFX-2 standalone USB data logger measures and stores over 250,000 temperature and humidity readings over a -30 to +80ºC (-22 to 176°F) and 0 to 100%RH range at a resolution of 0.1ºC and 0.1%RH. Using the Windows control software (available as a free download from www.easylogusb.com), 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. 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 ½AA batteries typically allow logging for up to four months.

* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH.
** This specifies the overall error in the calculated dew point for relative humidity measurements between 40 and 100%RH at 25°C.
*** At temperatures below -5°C the LCD will exhibit slower response times. The LCD will be disabled at temperatures under -20°C and above 70°C.
† At 25°C and 10 minute logging rate, with no alarm LEDs or sounder and minimal LCD use.

The EL-GFX-2 is suitable for a wide variety of applications, these include:

– Pharmaceutical fridge monitoring
– Transportation
– Food & drink
– Building & site monitoring
– HVAC
