Fluke Calibration Bath Fluids

Features

Full line of bath fluids covering temperature ranges from –100°C to 550°C

Viscosity, volatility and other properties that change with temperature affect the performance of fluids in controlled baths and circulators. Fluke Calibration has tested and used each of the fluids we sell. Over the ranges recommended in the following table, each fluid remains at a low enough viscosity to be adequately pumped or stirred. Whether your application is industrial or critical lab calibration work, Hart fluids give you top performance and stability.

For temperature ranges too high for oils, we have a bath salt with a viscosity in the molten state similar to the viscosity of water. For your convenience, it is shipped in a granular form, making it easy to fill your bath.

Between its melting point of 150°C and 550°C, this salt has the highest temperature stability and uniformity available in a bath fluid. It does not smoke like oils or give off dust like “sand" or fluidized alumina baths. Check with your bath manufacturer before using this salt to make sure your equipment is compatible. Fluke Calibration offers three standard bath models and custom-designed units for use with this salt

In addition to range and viscosity issues, there are a number of other issues to consider when choosing a bath fluid. The other considerations are:

  • Thermal characteristics
  • Lifetime
  • Change in characteristics due to temperature cycling
  • Absorption of water from the air
  • Vaporization—fumes and fume hood requirements
  • Expansion due to heat
  • Contamination—mixing oils or introducing contamination with unclean probes
  • Conductivity properties
  • Effects of using fluids outside of their range—fire, explosion, polymerization
  • Effects of altitude on boiling point

125 lb. bath salt fills a 7.9-gallon tank.

§ Atmospheric pressure affects the usable ranges of some fluids. The temperatures quoted are at sea level.
Flash point is the temperature at which a vapor (not the fluid) will ignite if exposed to an open flame. When the flame is removed, the vapor will stop burning. (Open cup method.)
