Brookfield Ametek Viscosity Standard Mineral Oil (Polybutene) B4900

Brookfield Ametek Viscosity Standards are accurate to ±1% of the stated viscosity and are certified by methods traceable to the United States National Institute of Standards and Technology (NIST). The selection of one or two fluids will normally provide sufficient measurement points to verify calibration of your instrument.
All fluids are supplied in 1/2 liter (1 pint) containers complete with a certificate of calibration. CAP Oil Fluids are supplied in 150 mL (4 oz) containers.
