The EL-GFX-D2 is a high accuracy, dual-channel* temperature and humidity data logger with external probes, enabling for two separate environments to be monitored simultaneously. The device has an LCD screen for live data viewings and a USB port for PC connection and data download. The device can measure and store over 250,000 temperature and relative humidity readings and has user-programmable alarm zones and an audible and flashing LED alarm if the set zone is breached. 

The high contrast, dot-matrix LCD screen gives real-time trend analysis and data summaries and buttons on the data logger give users the ability to start, stop and restart the data logger without connecting to a PC. EasyLog USB software enables quick configuration and data download via the USB port. Supplied with two lithium batteries, which can typically allow logging for up to 1 year. It can also be powered from USB.

*Please note: only one probe is supplied with the EL-GFX-D2. To use the dual-channel facility, you can purchase a second EL-GFX-SP-2 probe separately here.
