Data Sheet
Orion Features
  • Deep immersion depth (470mm / 18.5”) with low filling costs
  • Liquid Level to suit Liquid in Glass Thermometers - no level adaptors required
  • Variable Speed Stirring - allowing optimum performance for a wide range of liquid viscosities
  • Over and Under Temperature Protection - protect expensive Water Triple Point Cells as well as over temperature conditions
  • Automatic Power Up - no manual intervention needed - easier automation - energy saving

Calibration Volume
Liquid Bath Calibration

The Orion calibration baths offer deeper calibration volumes than the Isotech Hydra
series with world class temperature stability. There is a high temperature model (30°C
to 300°C) and a model with built in refrigeration (-40°C to 125°C).

The Orion unit has sufficient depth, 470mm (18.5”), 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 the on going 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.
