The Lascar EL-GFX-TC Thermocouple Data Logger is a standalone USB data logger that measures and stores up to 252,928 temperature readings from J, K, or T-type thermocouple inputs, at a resolution of 0.1°C. In the Windows control software users can set up the logger name, sample rate, alarm settings and start mode (immediate, push to start, delayed or temperature triggered). The software can be used to download the stored data which can be graphed, printed and exported. The software is free for download. 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 1/2 AA batteries.
