Description and Specification for Lab Tenders
Astra Scientific Automatic Cloud and Pour Point Analyser.
Standard: ASTM D2500, D5771, D5772, D5773
For Petroleum Products, cloud point and pour point of a petroleum
product is an index of the lowest temperature of its utility for certain
applications. The specimen is cooled at a specified rate and examined
periodically. The highest temperature at which a cloud is first observed
at the bottom of the test jar is recorded as the cloud point. The
lowest temperature at which movement of the specimen is observed is
recorded as the pour point.
Cloud Point Detection–The cloud point detection system provides
automated sample testing with the accuracy and repeatability in
accordance with ASTM D2500, D5771, D5772, D5773 and related
international test methods. The sophisticated dynamic measuring system
emits a light pulse every 1°C from a coaxial fiber optic cable
positioned above the test sample. The light pulse is then reflected off
the silver bottom test jar to an optical sensor. The advanced software
package analyzes the response of the light pulse. The initial appearance
of crystallization is monitored by light scattering, signifying the
cloud point of the sample. All clear and transparent oils are readily
measured by the detection system, regardless of sample color.
