Isotech, HYDRA series Calibration Baths (-80°C to 300°C)
Calibration Baths, Hydra Series Oil Baths

Liquid Calibration Baths, -80°C to 300°C (572°F) in Three Models

  • Parallel Tube Action — Liquid flows up the rear volume of the bath and down the working volume. This action creates very small vertical and axial gradients. Enabling the smallest overall uncertainties
  • Circular Design — The circular design eliminates cold corners in tank-shaped baths
  • Heating — All heating is outside the container. By using a large area nickel foil heater the complete bath wall is heated uniformly
  • Cooling — The cooling is built-in and also surrounds the calibration volume creating a low temperature ambient in which the heater can function efficiently
  • Wider Temperature Range — A unique system removes the coolant from around the calibration volume above ambient and lets the bath heat up to 125°C (121°C is a key sterilization temperature)
  • Stability — Better than ±0.030°C over the complete temperature range
