Tamson viscometer and Tamson calibration baths are specially designed for tests that require ultra-precise temperature control, or processes that need to be followed visually, e.g. determination of kinematic viscosity, thermometer calibration, crystal growing, density and reaction rate measurement, etc. All models are fitted with double windows in front and rear walls. The windows are formed with two panes of tempered safety glass separated by 20 mm air space. Visibility through the bath is excellent. The stainless steel construction with 25 mm thick rock wool insulation ensures exceptionally stable temperatures which is further improved by an ingenious stirring mechanism with baffle plates. All wetted parts are made of stainless steel, providing resistance against all usual bath fluids. The bath is fitted with adjustable feet for levelling. The cover of the bath has a number of round 51ø mm holes with lids, for suspending glass capillary viscometers in holders. To work at temperatures lower than ambient, use of cooling must be made. Cooling fluid can be pumped through the cooling coil inside the apparatus. Tap water or a combination with the TLC10-3 or TLC15-5 can be used for this purpose. All models are fitted with double windows in front and rear walls. The windows are formed with two panes of tempered safety glass separated by 20 mm air space. Visibility through the bath is excellent. A power plug on the back is mounted to provide power for an optional illumination unit (Z41 or Z71).
A vane type stirrer with brass bearings moves the bath fluid past the heaters and then from under the main baffle plate, thus directing the freshly heated fluid to the walls as well as window areas and creating an optimal temperature uniformity. All baths can be operated from ambient +5 up to +230°C (41..446°F). With the use of the built-in cooling coil, span lies 5°C above the temperature of the cooling liquid. The set point can be set in steps of 0.01°. The system overall accuracy is within ± 0.01°C. After the temperature control is stable the set point can even be adjusted with + or - 0.005°C. The TV4000 and TV7000DC stainless steel bath cover has seven openings with lids, arranged in two rows of resp. four and three openings. An optional cover for eight positions is available. The TV2000 offers three openings (2 + 1 lids). These openings of 51ø mm will accommodate glass capillary in holders (see our viscometer datasheet). Additionally, separate thermometers can be placed through two 12.5 mm holes in the cover. The bath conforms to CE regulations. It also is equipped with a mechanical adjustable and resettable safety thermostat. Advanced safety features are microprocessor control of:- Electronic- and processor system,- Control and feedback from each heating,- System accuracy.System error results in total cut-off from the power supply.
