Infrared Moisture Analyzer FD-800
FD-800 is an instrument positioned at the top of
Kett's infrared moisture analyzer series. It employs a
revolutionary dual temperature sensor method to enable
high precision moisture measurements. Conventional
models measured the temperature within the drying
chamber by using a thermistor, and controlled the heat
drying temperature. Temperature measurement using
thermistors is a procedure that is stable, and known
to be reliable through years of experience.
Description
FD-800 is an instrument positioned at the top of Kett's Infrared Moisture Analyzer series. It employs a revolutionary dual temperature sensor method to enable high precision moisture measurements. Conventional models measured the temperature within the drying chamber by using a thermistor, and controlled the heat drying temperature. Temperature measurement using thermistors is a procedure that is stable, and known to be reliable through years of experience. However, with a demand for an even more accurate moisture measurement, problems such as the temperature of the sample following the environmental temperature, and the fact that because of the shape of the sample it is difficult to maintain a constant distance between the test piece and the heater or thermistor, these inconsistencies have adversely affected the measuring accuracy. Thus, in addition to a thermistor, the tester is mounted with a radiation thermometer to measure the sample temperature without coming in contact with it. This complements to an extent the disadvantages of the thermistor, enables the user to optimize the heat drying settings to match the characteristics of the sample, and allows a reduction in measuring time and increase in measurement accuracy without burning or deforming the sample. This tester can handle highly advanced moisture control, and is positioned as a moisture sensor for quality control departments or testing divisions requiring a high level of moisture control.
