High Accuracy Temp/RH Data Logger with Graphic Screen
- -30 to +80°C and 0 to 100% RH measurement ranges
- Higher accuracy sensor when compared with the EL-GFX-2
- Immediate, delayed, push-button or temperature/RH triggered start mode
- Graphic LCD shows real-time readings, graph and current status
- Stores over 250,000 readings
- Calibration certificate available
The EL-GFX-2+ standalone USB data logger measures and stores up to 252,928 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 (0.1°F) and 0.1%RH.
Using the Windows control software (available as a free download from www.easylogusb.com) the user can quickly set up the logger name, sample rate, alarm settings and start mode (immediate start, push to start, delayed start or temperature/humidity triggered start). This software can later be used to download the stored data which can be graphed, printed and exported to other applications.
The data logger features a dot-matrix LCD and three face-buttons to navigate through an on-screen menu. This menu provides the user with access to real-time trend analysis, data summaries and the ability to start, stop and restart the data logger without the need to connect the data logger to the host-PC. Users can reset the maximum/minimum reading using the on-screen menu; this introduces an ‘event marker’ into the data which can later be viewed in the graphing software (‘Mark Events’ option) and the data file after download.
The data logger is supplied with two replaceable ½AA batteries.

* 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
– Food & drink
– Building & site monitoring
