Model EL-GFX-1

The EL-GFX-1 data logger offers a cost-effective approach to temperature data logging. Its integrated USB interface allows the instrument to be configured by any Windows-based PC. Typical programmable parameters include a unique data logger name, °F or °C temperature scale, sampling interval (10 seconds to 1 hour), high and low alarm limits, security settings, triggered recording parameters, and more. The GFX-1 is powered by two replaceable (non-rechargeable) ½ AA lithium batteries, for long-life recordings typically up to one year.

Model EL-GFX-1 provides a security option that can prohibit tampering of the logger in any manner that would affect recorded data after deployment.

The GFX also supports a programmable alarm delay feature, from immediate to after 250 readings. This is useful where temperature is known to fluctuate momentarily into an alarm threshold, but does not necessarily indicate an alarm condition. For example, the logger is placed inside a freezer or refrigerator. If the door opens the temperature will momentarily rise, but the logger can be configured to ignore that increase for a programmed number of samples before triggering an alarm.

During deployment, status LEDS provide continuous visual feedback of sampling events, battery status, and alarm states. In addition, three front panel function buttons allow you to view the memory consumed (0-100 %), the number of readings contained in the logger’s memory, and the current battery capacity (0-100 %.) The last recorded temperature can also be viewed, along with historical temperature data in the form of minimum and maximum temperatures logged during the current recording cycle, as well as an historical temperature trend plot. Using front panel buttons you can also start and stop the logger and view pre-programmed alarm thresholds.

The GFX-1 is programmed using software that is provided with the instrument. The software programs all operating parameters and options. When a logging session is complete, the GFX logger is plugged into any computer onto which the software is installed using the supplied cable. Options in the software allow the GFX logger to upload time, date and recorded data to the PC where they can be graphed in a cursor-based chart that displays temperature as a function of recorded time and date. A single mouse click can export the data to Microsoft Excel for detailed analysis and report generation.

The EL-GFX-1 is provided with everything you need to begin taking temperature measurements: USB cable for connecting it to a PC, batteries, and software (downloadable, no CD provided.) Also provided is a convenient wall clip that can be either permanently attached to a surface, or temporarily attached to a ferrous surface via the integrated magnet
