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 and is available with up to 11 openings. 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.
