Tannas Co. & King Refrigeration, Inc. Precision Laboratory Instruments for Routine Testing and Advanced Research & Development of Engine Oils, Lubricants, and Related Fluids

King BLB | Liquid Bath

Low-Temperature Viscosity

Test Methods

ASTM D2983 
IP 267
DIN 51398

Models Available

BLB 701
BLB 702
SimAir® | DIN Liquid Bath


The King BLB measures low-temperature viscosity of ATF's, gear oils and hydraulic oils, and other fluid lubricants using a patented SimAir® technique that allows the use of a small, less costly, constant temperature liquid bath.  The only technique available that permits independent sample analyses eliminates the need for batch sample testing. 

The BLB is a widely used low-temperature test for a variety of industry specifications.

Features & Benefits

  • 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

SimAir 4.jpg

The patented SimAir® Test Cells utilize a unique air-gap between the test sample and the liquid bath medium to simulate the original air bath method.

BLB SimAir Carousel - 12 Position.jpg

The BLB Test Cell Carousel accommodates twelve (12) samples, allows convenient alignment of each cell to the appropriate test position, and holds both SimAir® and DIN glassware.

Touchscreen Viscometer for BLB #.jpg

A user-friendly touchscreen viscometer facilitates D2983 and DIN 51398 testing.
