Tamson TV Viscosity Baths

D445, D2162
This test method specifies a procedure for the determination of the kinematic viscosity of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer.

Main Characteristics
Bath can be operated from ambient +5°C up to +230°C (41..446°F). With the use of the built-in cooling coil and an external Tamson cooler, span lies 5K above the temperature of the cooling liquid. The TV2000, TV4000 and TV7000 have a bath volume of 20, 40 and 70 liters respectivily. The TV2000 offers two rows of 2 and 1 holes with lids. The TV4000 and TV7000 have a stainless steel cover with 7 openings and lids. These will accommodate glass capilary viscometers in viscometer holders. The TV4000DC has the same specific qualities as the TV4000, but with a uniqe stability of 0.0007°C at 40°C. The TV7000 is often used to calibrate long thermometers, to calibrate master viscometers or for oxidation stability tests. A bath overflow outlet protects from expanding bath oil when the bath filling is too high. A bath drain is standard included. The bath is fitted with a double window of which the front pane is detachable for cleaning purposes.

Special Features
• Standard drain to empty bath.
• 0.01 readout in display
• Standard overflow outlet
• Unique temperature stability
• Large windows
• Removable outside window panes
