The EL-GFX-TC standalone USB data logger measures and stores up to 252,928 temperature readings from J, K, or T-type thermocouple input, at a resolution of 0.1ºC

Using the Windows control software (available as a free download from 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 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.

EL-WIN-USB - Control Software

Lascar’s Easylog USB control software is available to download from Easy to install and use, the control software runs under Windows XP, Vista and Windows 7. The software is used to set-up the data logger as well as download, graph and export data to Excel. Each stored logging session is saved as a separate file.

The software allows the following parameters to be configured:

  • Logger name
  • Measurement parameter (ºC or ºF)
  • Logging Rate (customisable between 2 seconds and 1 hour)
  • High and low temperature alarms
  • Immediate, delayed, push-button or temperature triggered start mode
  • Disable or enable LEDs and sounder with delayed activation
  • Display and backlight behaviour after button press
