Chauvin Arnoux L452 | Voltage and current data logger

Contact Instrument Solutions

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.


  • Oscilloscope, multimeter, analyser and recorder modes, with the recorded files directly viewable on the oscilloscope
  • Safety features include channels genuinely isolated from one another and from the earth, 6 V CAT III & Probix probes
  • Control panel for the data analysis software is a module that is fully integrated in the Dataview software
  • The instrument can also be configured using its front panel, with a
    very simple user interface
  • Multilingual menu options
  • Alarms can be set on the various measurements
  • Counter mode displays the measurement results in the unit selected
  • Programmable measurement campaign can be launched simply using the L452’s keypad
  • Users can lock the instruments keypad with the PC software
