Advanced On-Board Software

Advanced onboard software means there is nothing to install on your PC or Mac – simply connect the logger with a USB cable and use your web browser to configure the device and view, analyse and download your data. It really couldn’t be easier.
Choose from immediate, delayed, triggered or push-to-start logging. The display shows current, maximum and minimum readings, and three coloured LEDs indicate device status at a glance. Alarms are fully user-configurable, with functionality including cumulative alarms, pre-alarms, a delay before alarm triggering, and an alarm hold option. Recorded data can be downloaded to your computer, or uploaded to an EasyLog Cloud account for secure storage and powerful analysis.
