Microsep has extended its line of Mettler Toledo products to include the range of Ingold process control products. The Ingold product line provides end users and system integrators with solutions for effective process control through the measurement of pH, DO (dissolved oxygen), conductivity, turbidity and CO2 (carbon dioxide).
Conventional in-line measuring systems for analytical parameters usually consist of a transmitter and the corresponding sensor. The Mettler Toledo Ingold M 700 line transmitter is different in that it is based on a modular concept, allowing the simultaneous measurement of up to three parameters.
The basic unit is designed to accept modules for pH, conductivity and dissolved oxygen (DO). A special high-resolution module for dissolved oxygen is offered to enable measurements to be taken at ppb level. Additional modules for PID control, output and limit contacts, as well as a Profibus communication module are available.
The instrument offers its range of features through a menu-driven set-up program supported by graphical pictograms. The large and clear backlit LC display shows two process parameters. The side display can be configured to show process temperature, 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.
Two versions
The M 700 system comes in two versions. One version features a coated stainless steel enclosure that is used mainly in harsh chemical process applications. The second version comes in a robust hygienic stainless-steel enclosure, suitable for biotechnology, food and beverage as well as pharmaceutical applications. Both enclosures are available for standard power supply, are intrinsically safe and with ATEX approval as Ex versions for use in hazardous areas.
