BV4000 Brookfield Viscosity Air Bath
BV4000 Brookfield Viscosity Air Bath
Mechanically refrigerated cold cabinet prepares samples for Brookfield viscosity determinations on petroleum lubricants. A built-in turntable rotates the samples at 4 RPM per specifications. Cooling system maintains cabinet temperature within ±0.1°C at temperatures as low as –50°C. Cabinet temperature is displayed in digital format on the front panel. Cabinet accommodates sixteen (16) sample cells with cell carriers. Includes insulated cover.

Test Method
Determines the low temperature, low shear rate viscosities of gear oils, automatic transmission fluids, hydraulic oils and other fluid lubricants by use of the Brookfield viscometer.
