The Isotech Model 875 Fluidised Calibration Bath offers a high-quality calibration solution for a wide range of temperature measurements. This innovative system replaces hazardous salt baths and surpasses them in every respect: it has a wider temperature range (50\u00b0C – 700\u00b0C), is safer and offers better uncertainties. With more than 20 years of research and development in flow patterns, powder technology and filtration, this model is now a standard reference in national laboratories. Thanks to recent improvements, it is also suitable for the calibration of liquid-in-glass thermometers, thanks to a new filter system that can handle larger quantities of aluminium oxide powder.<\/p>\n

Superior temperature control and uniformity<\/h3>\n

The Model 875 uses aluminium oxide powder in a fluidised bed, in which an air flow through a porous base plate brings the powder into a liquid state. This creates homogeneous heat transfer without the need for metal blocks or other methods to improve stability. This system offers temperature uncertainty of \u00b10.035\u00b0C at 660\u00b0C in comparison set-up and even \u00b10.001\u00b0C to \u00b10.006\u00b0C when used with ITS-90 Fixed Point Cells such as Indium and Aluminium.<\/p>\n
