King BLB | Liquid Bath

With ASTM D2983, low-temperature studies by automobile manufacturers began in the 1950s due to the failure of automatic transmissions in cold temperatures. In 1971, a procedure was written and accepted as ASTM D2983. The original technique used a Balsa wood block to hold samples in a cold air cabinet. The samples were removed from the cabinet and tested with a rotational, bench-top Viscometer. In the mid-1990s, Tannas developed and patented the SimAir^® Test Cell for use in a constant temperature liquid bath to dramatically improve the test operation, usability, and precision.

The Cloud Point (ASTM D2500) test method for petroleum products and biodiesel fuels was originally approved in 1966. The cloud point is the temperature of a liquid sample when the smallest observable cluster of hydrocarbon crystals first appears at the bottom of the test jar when cooled under prescribed conditions and examined periodically.

Pour Point method (ASTM D97) was originally approved by ASTM in 1927 and is still used today as the manual technique for pour point testing. The lowest temperature at which movement of the sample is observed is recorded as the pour point.

• Unique Tannas SimAir^® Test Cells provide proper sample temperature control for accurate, precise results and permits each test cell to operate independently, increasing productivity.
• Features a 12-position carousel with 12 independent sample cells
• BLB models: Capable of measuring a broad temperature range of +30°C to –70°C (BLB702) and +30°C to –40°C (BLB 701).
• SimAir^®/DIN model: Capable of measuring a broad temperature range of +30°C to –55°C.
• Fully self-contained internal hermetic refrigeration system – no external refrigeration units or controllers needed.
• Digital temperature controller keeps bath temperature within +/- 0.1°C.
• Small benchtop footprint with large illuminated viewing window.
• Includes top mount for viscometer (viscometer available separately).
• The internal air system provides a continuous blanket of dry air over samples to eliminate moisture buildup.
• Safety features include a high-pressure cutout, high-temperature limits, and low-level shutdown.
• CE Mark
