The UM700 is an infrared photometric analyser which uses fixed near infrared wavelengths to measure the amount of moisture contained in a variety of products. The system is based on the capacity of the materials to absorb certain wavelengths of infrared radiation. Material temperature readout may be added as an option. The UM700 is a “stand-alone” sensor for the on-line monitoring of moisture content. Optional wall-mountable or hand-held operator interfaces are available for setup, calibration and maintenance. In applications where material needs to be collected from a downward flow, for example from inside a chute, a material collecting system may be supplied. It is possible to add a second cooling kit if temperatures are very high in the installation area or, on the contrary, a heated cover for areas where temperatures are low to maximize efficiency.
