DESCRIPTION
Stirred Ice Bath Model 813 (Obsolete)
The Stirred Ice Bath Model 813 is no longer available. For similar applications,
please consider the following current stirred liquid bath solutions:
- Large Volume Calibration Bath Model 820
A robust stirred liquid bath with a 15 litre volume and working area
of 185 mm × 140 mm × 300 mm, ideal when you need to calibrate a
larger number of sensors at the same time. The 820 covers 30 °C to
200 °C with typical absolute stability of ±0.003 °C in water at 50 °C
and good uniformity across the bath.

- Hydra 798 Stirred Liquid Baths
A family of deep stirred liquid baths with 150 mm diameter × 300 mm
deep calibration volume (approx. 5 litres), operating from
-80 °C to 300 °C depending on model. Hydra uses parallel tube
circulation for excellent vertical and radial uniformity, with immersion
depths up to 300 mm to support low-uncertainty calibration of
thermometers.

application, please contact Isotech for guidance.
Model 813 (Legacy)
The most used temperature for calibration is 0°C.
The normal way of creating 0°C is via a mixture of ice and water in a Dewar Flask.
However, this can give errors of up to 4°C because water is densest at 4°C and so as the ice melts the temperatures at the bottom of the flask can rise to 4°C.
In the design of the ice flask offered by Isothermal Technology Ltd., these problems have been eliminated by stirring the water/ice mixture and segregating the ice from the water in the measuring zone.
This stirred ice/water bath is designed and built according to National Laboratory recommendations.
Using demineralised water, accuracies of ±0.005K are obtainable. Typically the bath will last for 4 hours before recharging with ice.
The ice is contained around and below the compartment where up to 4 probes can be placed for calibration or referencing purposes.
An option permits a water triple point cell to be maintained within the stirred ice bath.
