Combining a revolutionary patented built-in cooling system and highly precise detection mechanism, ISLs CPP 5Gs performs pour and cloud point testing of any petroleum products, down to -95C (-139F), in accordance with all the international standards. Its unique cooling technology eliminates external liquid connections, heat, and noise, but also the maintenance associated with external cooling. Automation enables unattended operation with excellent reproducibility and repeatability. It is ready to work whenever and wherever you are; simply plug in the electrical cord, and begin testing. Pour point is detected by tilting the sample no turning, pressing or twisting as an optical surface, whereas detection system precisely monitors movement of the specimen surface. Optics detect cloud point in the specimen when wax crystals first appear.
