The Chauvin L452 Data Logger is used to check and measure process applications, water, gas, and power meters, or to monitor the environment. It can operate in the local mode or in the remote mode. It can communicate by USB or by Bluetooth.

Ideal for your industrial process applications, such as measurement, dosing or environmental monitoring, the L452 is equipped with 2 inputs. It allows you to connect various types of sensors to the input in order to record varied data. The voltage and current measurements can be sampled at intervals from 200ms to 1 minute. The sampled quantities can be averaged (means) over periods from 200ms to 1 hour and recorded in the internal memory.

For each of the channels, a real-time measurement is displayed on the LCD screen. The L452 communicates via a USB input and the Bluetooth function for configuration and data transfer onto a PC. Its ergonomics makes it even simpler to use: magnetized rear panel, Multifix system, desktop stand. It operates on rechargeable batteries or the mains supply.
