The Isotech Orion 796 Liquid Baths offer deep calibration volumes, with world class temperature stability. There is a high temperature model 86 to 572°F (30°C to 300°C), and two models with built-in refrigeration -40 to 257°F (-40°C to 125°C) and -112 to 257°F (-80°C to 125°C).

The Orion 796 baths are suitable for the low uncertainty calibration of long thermometers, including liquid-in-glass and extended-length SPRTS. The Orion unit has sufficient depth, 470mm (18.5in), to accommodate Isotech's largest Water Triple Point Cells, providing a cost-effective sub mK calibration system. There are accessories to hold mercury, water, gallium, and indium ITS-90 Fixed Point Cells.

Isotech baths have always been designed for thermometer calibration, setting the standard for immersion depth versus filling costs. As the Orion requires just 8.5L of fluid, it offers significant cost savings, both initial and ongoing running costs, when compared to other, larger volume baths. In operation, the liquid level is within 10mm of the top lid, allowing calibration of liquid-in-glass thermometers without the need for complicated accessories.
