The Simple Logger II models automatically adapt their sensitivity (measurement range) and their acquisition rate to optimize recording. It is possible to program alarms or triggers on thresholds or on a predefined range. The LEDs on the front panel enable users to check the status of the logger and the remaining storage capacity at a glance. Compact and battery-powered, the Simple Logger II L481 is easy to position, even in an electrical cabinet.
