MICHELL Instruments has introduced a new S8000 RS high-precision dew-point hygrometer
that enables furnace operators to achieve high standards of finishes and quality of metal products at lower annealing temperatures.
Other devices, such as a chilled mirror dew-point hygrometer, can also be used to establish the moisture content of an air stream.
A small vacuum pump is used to draw a small sample of air from the test section of the duct and across the chilled mirror dew-point hygrometer sensor, where the dew-point temperature is measured.
Michell Instruments' MDM300 advanced dew-point hygrometer
can save engineers weeks of waiting time each year.
The sampling tubes were connected to a dew-point hygrometer
via an air-sampling pump.
