The M400 transmitter series features advanced ISM technology and covers pH /ORP, pH ISFET, oxygen, carbon dioxide, and conductivity - inductive as well as 2-E and 4-E - measurements . Thanks to the mixed-mode input functionality, the M400 accepts any conventional (analog) or ISM sensor of your choice. Combined with its multi-parameter capabilities, the M400 is the state-of-the-art transmitter for your most demanding applications.
The M400 is a single-channel, multi-parameter unit. The same unit can handle different parameters such as pH/ORP, pH ISFET, oxygen, carbon dioxide or conductivity - inductive as well as 2-E and 4-E - , depending on the type you choose.
