Isotech<\/a> 798 Hydra series offers a versatile range of stirred liquid baths designed for precise and reliable temperature calibration across a wide span from \u201380 \u00b0C to 300 \u00b0C. With deep immersion, excellent uniformity and efficient fluid circulation, the Hydra provides performance that is rarely found in this price class.<\/p>\nDeep immersion that meets ITS\u201190 recommendations<\/h3>\n
With an immersion depth of 300 mm, the Hydra meets the recommendations of the Supplementary Information to the ITS\u201190<\/em>, which calls for immersion depths of 15\u201320 cm between \u201350 \u00b0C and 50 \u00b0C, and 20\u201327 cm at 200 \u00b0C. Many baths in this category fall short, but the Hydra provides ample depth for long thermometers, SPRTs and industrial sensors.<\/p>\nParallel Tube Action \u2014 superior uniformity<\/h3>\n
Instead of relying on simple stirring, the Hydra uses a parallel tube flow system. Fluid rises in the rear chamber and descends through the working volume, minimizing vertical and axial gradients. This produces a highly isothermal calibration zone and ensures low overall uncertainties.<\/p>\n
Efficient design with low fluid volume<\/h3>\n
The calibration volume is 150 mm in diameter and 300 mm deep, yet requires only 5 litres of fluid. This reduces both initial and ongoing operating costs, especially when using specialty oils or alcohols. The circular design eliminates the cold corners often found in square tanks.<\/p>\n
Advanced cooling and fast stabilization<\/h3>\n
The 798L and 798M models include built\u2011in refrigeration, while the 798H features an external cooling coil that can be connected to cold water or gas for faster cooldown. The Hydra cools from ambient to \u201380 \u00b0C in about 130 minutes, and heats from 25 \u00b0C to 200 \u00b0C in under an hour.<\/p>\n
Thermal performance<\/h3>\n
The Hydra delivers excellent stability and uniformity:<\/p>\n
\n- Absolute stability:\n
\n- \u00b10.030 \u00b0C (ethanol, \u201380 \u00b0C)<\/li>\n
- \u00b10.017 \u00b0C (ethanol, \u201340 \u00b0C)<\/li>\n
- \u00b10.015 \u00b0C (oil, 250 \u00b0C)<\/li>\n<\/ul>\n<\/li>\n
- Vertical uniformity:\n
\n- \u00b10.002 \u00b0C (oil, 50 \u00b0C)<\/li>\n
- \u00b10.005 \u00b0C (oil, 200 \u00b0C)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
\n- <\/li>\n<\/ul>\n
These characteristics make the Hydra suitable for high\u2011accuracy comparison calibration with SPRTs, PRTs and industrial sensors.<\/p>\n
Ease of use and practical features<\/h3>\n
The Hydra benefits from Isotech\u2019s long experience in liquid bath design. It drains quickly, is easy to operate and includes:<\/p>\n
\n- > over\u2011temperature protection<\/li>\n
- > commercial\u2011grade chillers (1\/3 HP)<\/li>\n
- > overflow and drain connections<\/li>\n
- > compatibility with sensor supports and ITS\u201190 fixed\u2011point cell holders<\/li>\n<\/ul>\n
This combination of features makes the Hydra both robust and highly practical.<\/p>\n
The Isotech 798 Hydra delivers deep immersion, excellent uniformity and strong thermal stability in a compact, cost\u2011effective package. With its parallel tube action, low fluid requirement and wide temperature range, the Hydra is an outstanding choice for laboratories seeking reliable and accurate temperature calibration.<\/p>\n
