Measuring Freezing Point Principle

According to the methods, the sample is cooled down and stirred. The solid hydrocarbon crystals formation are observed by the operator. As soon as crystals are detected, the sample is warmed up until their complete disappearance.

Measuring Temperature Probe

• Thermometer

Stirrer

• A micro-motor drives all the mechanical system
• 3 coils stirrer made of brass

Measuring Parameters

• Temperatures: in °C/°F
• Measuring range: +80°C … -100°C
• Resolution: 0.1 °C
• Accuracy: ± 0.1 °C
• Repeatability / reproducibility as per standards methods or better

Test Jar

• Same dimensions and volume as described by the standard test methods
• Product level mark at 25 ml
• Small edge on the top in order to fix the glass cell to the analytical head

Cooling System

• Insulated cooling jackets.
• Integrated gas CFC free motor compressors: Double stage, for temperatures up to -85°C / 2.
• Equipped with an automatic energy power save system. After 15 minutes from the end of the analysis the cooling system goes in stand-by mode.

Safety Devices

• Pressure controller for 1st stage motor compressor
• Pressure controller for 2nd stage motor compressor
• Thermostat for 2nd stage activation
• Thermo-switch for each cooling / heating jacket
• Motor compressors equipped with internal overload devices

Electrical Supply

• 220V ± 15% / 50 to 60 Hz
• 115V ± 15% / 60 Hz
