Pour Point ∙ Asphaltene ∙ Wax ∙ Scale ∙ Gas Hydrate ∙ Viscosity ∙ Drag Reduction ∙ Thermal Conductivity

• Measuring thermal conductivity of fluids, powders

nano fluids and gels

• Based on ASTM D 2717
• Temperature range -30 to +190 °C (-22 to +374 °F)
• Ambient pressure or pressurised up to 35 bar (507.6 psi)
• Small sample volumes from 50 ml
• Stand-alone or PC-controlled

Characteristics

Pour Point ∙ Asphaltene ∙ Wax ∙ Scale ∙ Gas Hydrate ∙ Viscosity ∙ Drag Reduction ∙ Thermal Conductivity

• Hot wire is heated up by

a well known amount of electrical energy

• Heat is corried off by inter-

molecular heat transfer

• The wire resitance changes

while cooling down

• The thermal conductivity can be

calculated out of the resistance curve

• Convection causes additonal

heat transfer and would disturb the measurement

• For measuring only the inter-

molecular heat transfer any convection has to be avoided !

• The LT30190 thermoelectric thermostat

provides most accurate and fast zero- convetion tempering

Why use a zero con- vection thermostat?
