By connecting 4-20mA modules and 0-10V modules and/or various sensors to the Chauvin Arnoux L452 2-Channel Datalogger’s two independent inputs, this module can be used to measure and record current, voltage, temperature, humidity and airspeed.
In addition to measuring and recording these entities, the Chauvin Arnoux L452 2-Channel Datalogger also includes a number of measurement features, optimised to improve the ease and efficiency with which users may acquire necessary measurements, for instance:
The Chauvin Arnoux L452 2-Channel Datalogger also includes an event counter and is capable of dry contact closure and logical level detection.
In order to configure the Chauvin Arnoux L452 2-Channel Datalogger, the operator may utilise its front panel and simple-to-use interface with multi-lingual menus. Alternatively, he/she can use Chauvin Arnoux’s DataView® Software (NOT included) to configure the instrument. This software can also be used to store, analyse and organise data into reports.
Measurements may be sent to a compatible PC via the USB input or the Chauvin Arnoux L452 2-Channel Datalogger’s Bluetooth connectivity. Data acquired via each of the channels is also displayed in real-time on the LCD screen.
In terms of its practicality, the Chauvin Arnoux L452 2-Channel Datalogger includes a magnetised rear panel and desktop stand, as well as a multiflex system, ensuring that it can be set up easily in a variety of environments and is suitable for hands-free usage.
Additionally, the user is able to tailor the Chauvin Arnoux L452 2-Channel Datalogger to his/her requirements as it may be powered using either batteries or a mains supply.
The Chauvin Arnoux L452 2-Channel Datalogger is a versatile, compact, practical datalogger ideal for use across a variety of environments.
