Multi-parameter monitoring

In-situ Fluorescent DO Detection


Multi-parameter monitoring MPA48


Insite-MPA48 is a multi-parameter analyser utilising system that combines advanced electronics with solid state optical sensors. The analyser will accept any combination of 4 to 8 sensors (DO, SS, pH, and ORP) and automatically configure for the correct operation. The system allows for flexible and economical process monitoring and control.

The DO sensor does not need membranes, fill solutions, nor routine calibrations and maintenance. The SS sensor is based on near infrared technology, which eliminates inaccuracies caused by changes in the process colour or changes in particle size. The pH and ORP electrodes are both flat glass, with double reference junctions, and temperature compensated. Both probes feature quick disconnect cartridge design for easy maintenance and fast changes.
