PP measurement on this cloud and pour point apparatus is by AIR PRESSURE METHOD (ASTM D6749), and CP measurement is by SMALL TEST JAR METHOD (ASTM D7683).

The epoch-making automatic PP test method yields 1C test resolution, while the new CP method yields 0.1C resolution.

The cloud and pour point apparatus is available in 6 models: model 490/HS/140 with 4 positions operating at temperatures as low as -69C; model 500/S with 4 positions each for 4 different temperatures (0, -18, -33, and -51C); model 510/S with 4 positions each for 3 different temperatures (0, -18, and -33C); model 520/S with 4 positions each for 5 different temperatures (0, -18, -33, 52, and -69C); model 530/S with 4 positions each for 6 temperatures ( 50, 0, -18, -33, -33, -51, and -69C); and model 540, the conventional cloud and pour point apparatus, operating at temperatures as low as -69C with dry ice.

Designed for simple use at extremely low temperatures, the cloud and pour point refrigerators are each equipped with an automatic defrosting mechanism and a digital thermoregulator fitted with a PT100 A temperature probe, ensuring stable temperatures as low as -69 C. Additional features of the cloud and pour point apparatus include a glossy black PVC cover with small stand-by covers and aluminum blocks with holes to accommodate graduated jars.

The cloud point refrigerators are equipped with four wheels and brakes for easy mobility around thelaboratory. The instruments are sealed with an anti-acid epoxidic coat, preventing corrosive damage andensuring durability for years to come. Because operator safety is crucial, the cloud point tester’s refrigerators are fitted with an earth leakage circuit, and refrigerant gases are CFC-free.

The DR6 and DR7 series automated analyzers are nearly identical in design and configuration. The only difference is the number of test positions. The DR6 is a single test position instruments, while the DR7 series signifies dual test positions.

All DR6 and DR7 instruments come fully loaded with all necessary accessories ready to run at full capacity out of box.

A wide variety of refrigerated water bath models are available with working temperature ranges from 48 to -69 C to test cloud point, pour point, and cold filter plugging point of petroleum products. Each multi-bath unit conforms to ASTM D97 pour point and ASTM D2500 cloud point test methods and related methods. Each stainless steel liquid bath has its own digital indicating PID temperature controller with 0.1 C resolution, providing temperature stability of 1.5 C. The baths of select models are agitated for improved temperature stability (0.5 C) and uniformity, making them suitable for ASTM D6371 (or IP309) cold filter plugging point test with the addition of the CFPP kit (see options tab).

Each refrigerated water bath comes equipped with 4 metal test jackets, 4 cork rings, 4 O-rings, and 4 cork stoppers for the thermometer (test tube is available separately). All units are mechanically refrigerated using ozone friendly non-CFC and non-HCFC refrigerants, making the instruments a sustainable choice in petroleum testing.

TANAKA?s MPC series of cloud point testers and pour point analyzers have been designed for automatic determination of POUR POINT (PP) and CLOUD POINT (CP) with small specimen size and shorter test cycle time while securing better test precision than the conventional manual methods.

PP measurement is by ?AIR PRESSURE METHOD? (ASTM D6749), and CP measurement is by ?SMALL TEST JAR METHOD? (ASTM D7683).

The epoch-making automatic PP test method used by the Tanaka MPC-102S pour point analyzer yields 1?C test resolution, while the new CP method yields 0.1?C resolution. (Cloud point analyzer shown with optional printer).
