Ideal for industrial process applications such as the outputs from various types of environmental sensor such temperature, humidity and air velocity. The Chauvin Arnoux L452 is equipped with 2 input using 4 to 20 mA and 0 to 10 V modules. 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. The unit's ergonomics make it simple to use including magnetized rear panel, Multifix system and desktop stand. It operates on rechargeable batteries or the mains supply.
