May 2018 "Michell has relaunched its flagship S8000 precision hygrometer range with improved features, common user interface and new look"
The chilled mirror hygrometers from Michell cover a dew-point range from -100°C dp to +120°C dp, using both integral and remote sensors. The remote sensors can survive environmental temperatures up to +120°C, so can often be positioned directly at the point of interest.
The all-new S8000 series instruments now use the same intuitive, touch-screen HMI, making it easier to use and configure. For multi-instrument users, the common interface makes it simple to switch between models – which is a key feature for many operators. A complete range of communication options are now available on all models, giving the option of USB, Ethernet, RS232 or RS485 to take the hassle out of establishing connectivity with your system. All models feature data logging to SD card as standard for convenient standalone operation.
The cases have also been updated to a fresh, easy to clean surface and distraction-free look.
These high-precision instruments use the fundamental chilled mirror principle to ensure reliable and drift-free measurements of dew-point. The S8000 RS is a real ‘work-horse’, with an accuracy of ±0.1°C dew point, which can measure dew points down to -90°C with no need for additional cooling. Typical applications range from use as a calibration reference, to industrial settings where precise control of humidity is critical, such as semi-conductor manufacture.
The S8000 Remote combines high accuracy with a remote sensor for measuring directly in the process. Typical applications include environmental chamber verification, pharmaceutical manufacture or as a National Measurement Institute traceable precision reference tool for field calibrations.
Sintering is a process where powdered metals are bonded together to form light and strong products, from filters to machine parts. Because the powdered metal is not fully melted, the temperatures involved are relatively low – around 600°C – but careful control of moisture is essential to ensure the finished quality. Because the raw material is powdered metal, moisture present in the furnace could cause clumping or, as the moisture evaporates in the heat, large holes being created in the finished product. To avoid this, accurate control and measurement of moisture is vital.
For sintering carried out 600°C, maintaining a constant dew point of -60°C in the furnace is necessary and the gas is sampled at several points in the process. A fast-responding moisture analyzer is essential so that action may be taken quickly if moisture levels rise above acceptable limits.
The Michell’s S8000RS uses the fundamental chilled mirror technique to measure moisture, which ensures long-term accuracy to ±0.1°C dew point as well as reliability and a fast response. The measurement range of -80 to+20°C dp is ideal to ensure consistent monitoring at -60°C with confidence in the accuracy.
The S8000RS is the smallest hygrometer on the market which is able to reliably reach dew points of -80°C. This small size is possible because it does not require any external cooling, which makes it well-suited to metallurgical applications where its small footprint makes it easy to install in an air conditioned instrumentation cabine
