Short description

The M400 2-wire transmitter series is the state-of-the-art transmitter for most demanding conditions in

hazardous area applications. The transmitter series features advanced ISM technology and covers pH /ORP,

amperometric Oxygen, and Conductivity measurements. Thanks to the mixed-mode input functionality, the

M400 accepts any analog or ISM sensor of your choice. The M400 is a single-channel, multi-parameter unit.

The same unit can handle different parameters such as pH/ORP, amperometric Oxygen (for measurement of

dissolved oxygen or in gas) or Conductivity, depending on the type you choose.
