The M 700 is based on a modular concept, allowing the simultaneous measurement of up to three parameters like pH, ORP, Conductivity, Temperature and Dissolved Oxygen. The M 700C is a coated steel enclosure that is mainly used in harsh chemical processing in hazardous areas. The M 700S design comes in a hygienic stainless steel enclosure, suitable for pharmaceutical applications. The large, clear backlit LC display shows process parameters, sensor-related data, differential measurement and other important information. Special attention has been paid to the many maintenance functions and sensor diagnostic tools implemented in the basic unit of the M 700. A variety of options, such as an extended logbook, a 2-channel measuring recorder, a service scope function, FDA 21 CFR Part 11 compliance and other software options, are available to optimize the functionality of the M 700 according to customer needs. In addition, all data and configurations are stored on a SmartMedia card for an easy exchange.
