The Lascar EL-GFX-DTP Dual Channel Temperature Data Logger is a standalone USB model that measures and stores over 250,000 temperature readings from two thermistor probes over a -40 to +125°C range at a resolution of 0.1°C.

The logger has a LCD display the three face buttons to navigate through and on-screen menu. The menu provides access to real-time trend analysis, data summaries and the ability to start, stop and restart without the need to connect the data logger to the host PC.

Users can reset max/min readings using the on-screen menu which introduces an ‘event marker’ into the data which can later be viewed in the graphic software (under ‘Mark Events’) and the data file after download.
