The Lascar Accuracy Temperature, Humidity and Pressure USB Data Logger, now available from RS Components, needs no software installed on a user's PC or Mac. Just connect the logger with a USB cable, and utilise a standard web browser to configure the device for logging.
The logging interval can be set between ten seconds and 24 hours, with recording via immediate, delayed, triggered or push-to-start logging. Alarms are completely user-configurable, with functionality including pre-alarms, cumulative alarms, a delay prior to alarm triggering, and an alarm hold option, which continues displaying the alarm condition even if the reading reverts to an acceptable level.
The display exhibits current, maximum and minimum readings, and three coloured LEDs show device status at a glance.
The device has a typical battery life over one year using standard AAA alkaline batteries. The logger can also be wall-mounted.
