Product Description


Dual Channel Thermocouple Data Logger with Graphic Screen

The EL-GFX-DTC standalone USB data logger measures and stores over 250,000 temperature readings from two J, K, or T-type thermocouple inputs at a resolution of 0.1ºC. Using the Windows control software (available as a free-download from www.easylogusb.com), users can quickly set up the data logger and view downloaded data by connecting the device to the PC’s USB port using the supplied cable.

The data logger features a high-contrast graphic LCD and three-input buttons which allows users to start, stop and restart the data logger using on-screen menus. This menu also provides real-time analysis of data either as a data summary (showing highest & lowest readings and alarm conditions) or as a graph that updates as new data is added. Multiple data logging sessions can be stored on the device ready for upload to a PC at a later date.

The two replaceable ½AA batteries typically allow logging for up to four months

* Above 999.9°C/F display becomes 1°C. Internal resolution remains at 0.1°C/F.
** Quoted accuracy is for the data logger only when measuring within the specified operating temperature. Thermocouple error is not included and should also be taken into consideration.
*** Operating temperature applies to the data logger module only. Please consult the probe manufacturer for operating temperature of thermocouple.
† At 25°C and 10 minute logging rate with no alarm LEDs or sounder and minimal LCD use.
