Low Temperature Viscosity Measured by Brookfield ViscometerK34702 Brookfield Viscosity Air Bath (BV4000)New BV3000 Brookfield Viscosity Liquid Bath• Permits viscosity measurements without the risk of temperature increase• 10 sample turntable• Mechanically refrigerated with digital indicating temperature control• Operating range to –55°CConstant temperature liquid bath permits testing of samples without the riskof sample temperature rise. After cooling in the air bath, the sample must betransferred to the balsa cell carrier for testing with the Brookfield viscometer.If the sample is not tested quickly, there is the risk of sample temperature rise.The Brookfield Viscosity Liquid Bath eliminates this risk by permitting thesample to be tested in a constant temperature environment. The Brookfieldviscometer mounts directly on the bath and the samples are rotated intoposition under the spindle by means of a built-in turntable. Cooling systemmaintains temperature with ±0.05°C stability in the range of +10°C to –55°C.Bath temperature is displayed in digital format.SpecificationsConforms to the specifications of: Note 7 of ASTM D2983Sample Capacity: 10 samplesTemperature Range: +10°C to –55°CTemperature Control Stability: ±0.05°CElectrical Requirements:115V 60Hz, Single Phase, 16A220-240V 50 or 60Hz, Single Phase, 12ATest MethodDetermines the low temperature, low shear rate viscosities of gear oils,automatic transmission fluids, hydraulic oils and other fluid lubricants byuse of the Brookfield viscometer.New BV4000 Brookfield Viscosity Air Bath• Conforms to ASTM D2983 and related specifications• Mechanically refrigerated with digital indicating temperature control• Operating range to –50°C• Sixteen sample capacityMechanically refrigerated cold cabinet prepares samples for Brookfield viscositydeterminations on petroleum lubricants. A built-in turntable rotates the samplesat 4rpm per specifications. Cooling system maintains cabinet temperaturewithin ±0.1°C at temperatures as low as –50°C. Cabinet temperature isdisplayed in digital format on the front panel. Cabinet accommodates sixteen(16) sample cells with cell carriers. Includes insulated cover.SpecificationsConforms to the specifications of:ASTM D2983; IP 267 Method A; ISO 9262; CEC-L-18ACapacity: 16 sample cells with cell carriersTemperature Range: +10°C to –50°CTemperature control accuracy: ± 0.1°CSample Rotation: 4rpmElectrical Requirements:115V 60Hz, Single Phase, 16A220-240V 50 or 60Hz, Single Phase, 12ADimensions: lxwxh,in.(cm)36x28x43 (91x71x109)Net Weight: 315 lbs (143kg)Shipping InformationShipping Weight: 380 lbs (172kg)Dimensions: 38.9 Cu. ft.Catalog No.K34710K34711K34712K34700K34701K34702Software compatible, inquirewith Koehler Customer Service.Ordering InformationBV3000 Brookfield Viscosity Liquid Bath, 115V 60HzBV3000 Brookfield Viscosity Liquid Bath, 220-240V 50HzBV3000 Brookfield Viscosity Liquid Bath, 220-240V 60HzBV4000 Brookfield Viscosity Air Bath, 115V 60HzBV4000 Brookfield Viscosity Air Bath, 220-240V 50HzBV4000 Brookfield Viscosity Air Bath, 220-240V 60HzDimensions: lxwxh,in.(cm)17x24x25(43x61x25)Net Weight: 265 lbs (120kg)Shipping InformationShipping Weight: 300 lbs (136kg)Dimensions: 13.9 Cu. ft.14
Low Temperature Viscosity Measured by Brookfield ViscometerBV5000 Programmable Brookfield ViscosityLiquid Bath• Sample soaking and testing in a single bath, eliminating the need for anair bath and the risk of sample temperature rise during transfer• Redesigned for improved control of sample movement and handlingduring testing• Microprocessor PID temperature control duplicates the sample coolingrates in ASTM D2983• Up to 40 cooling/testing temperature profiles can be stored in memoryRedesigned programmable baths with improved features for sample handlingand testing. Bath accommodates 10 samples for Brookfield Viscosity testing.Sample cells are immersed in a liquid bath for the entire soaking and testingperiod, eliminating the need to transfer cells from an air bath to a liquid bathwith insulated balsa wood carriers. Also eliminated is the inherent risk ofsample temperature rise during transfer. The programmable microprocessorPID controller stores up to 40 temperature profiles that duplicate the samplecooling rates found in ASTM D2983. Steady state temperature accuracy anduniformity exceed ASTM requirements throughout the operating range fromambient to -55°C. Air-cooled hermetic compressors provide efficient operationwith the use of CFC-free refrigerants.The mounting position for the Brookfield Viscometer has been changed topermit easier access to the samples and viscometer controls. Cabinet has afront window and glare-free fluorescent lighting for distortion free viewing ofthe sample cells. Cabinet construction is polyester-epoxy finished steel with achemical-resistant composite top surface. A removable insulated cover withhandle is included. Bath rests on adjustable leveling feet. Safety featuresinclude a probe fault detection circuit in the primary temperature controller anda redundant latching controller and probe for temperature fault protection.SpecificationsConforms to the specifications of:ASTM D2983 - Note 1 and Appendix X3; IP 267; CEC L18A-30; ISO 9262Sample capacity: 10 samplesTemperature control: Microprocessor PID digital-indicating programmablecontroller with ±0.05°C steady state stabilityOperating Range: ambient to –55°CElectrical Requirements:220-240V 50 or 60Hz, Single Phase, 12.6ADimensions: lxwxh,in.(cm)41x34x38 (104x86.5x96.5)Net Weight: 327 lbs (148.5kg)Shipping InformationShipping Weight: 497 lbs (226kg)Dimensions: 41.5 Cu. ft.Catalog No.K34715K34716Software compatible, inquirewith Koehler Customer Service.Ordering InformationBV5000 Programmable Brookfield Viscosity Liquid Bath,220-240V 50HzBV5000 Programmable Brookfield Viscosity Liquid Bath,220-240V 60HzK34715 Programmable Brookfield Viscosity Liquid BathAccessoriesCatalog No.Order QtyK34750 Brookfield Digital Viscometer, 115V 60Hz 1K34751 Brookfield Digital Viscometer, 220-240V 50HzK34752 Brookfield Digital Viscometer, 220-240V 60HzK34760 Brookfield Programmable Viscometer, 115V 60Hz 1K34761 Brookfield Programmable Viscometer, 220-240V 50HzK34762 Brookfield Programmable Viscometer, 220-240V 60HzK34706 Insulated Spindle No.4B2 1K34707 Cell Stopper 12K34708 Insulated Cell Carrier (for Air Bath) 1K34709 Test Cell - Round Bottom (pack of 12) 1K34770 Test Cell - Flat Bottom (pack of 12) 1250-000-122C ASTM 122C/IP94C Thermometer 1Range –45 to –35°C250-000-123C ASTM 123C/IP95C Thermometer 1Range –35 to –25°C250-000-124C ASTM 124C/IP96C Thermometer 1Range –25 to –15°C250-000-125C ASTM 125C/IP97C Thermometer 1Range –15 to –5°C355-005-027 Viscosity Standard N27B 1Viscosities in centipoise at –40, –30, –20, –15, –10, 0°F355-005-115 Viscosity Standard N115B 1Viscosity in centipoise at –20, –15, –10, 0, +10, 20°FFor NIST traceable certified thermometers, please refer to the ASTM Thermometer section onpages 184 through 191.15
