Operating Instructions: Transmitter M400

The M400 multiparameter transmitter is a single- channel online process instrument for measuring various properties of fluids and gases. These include Conductivity, Dissolved Oxygen, Dissolved Carbon Dioxide (CO2) and pH / ORP. The transmitter handles also ISFET sensors used for pH measurement. The M400 is available in three different levels. The level indicates the amount of measurement parameters which can be covered. The parameters are indicated on the label on the back of the system.

The M400 is a unique mixed mode transmitter who can handle conventional sensors (analog) or ISM sensors (digital).
