New Low temperature Viscosity 12 litre bath

May 28 2009

Tamson Instruments (The Netherlands) is proud to introduce an new viscosity bath. The TV12LT is a unique small-sized visibility bath. Working temperature ranges from minus 40°C up to plus 100°C. An integrated cooling system is able to lower the bath temperature down to minus 40°C. The cooling power can be controlled so that the heat removal capacity is trimmed to the desired set point temperature, saving up to 75% of energy in comparison to conventional systems.

Tamson viscometer and Tamson calibration baths are specially designed for tests requiring an ultra precise temperature control, or processes which need to be followed visually, e.g. viscometry, thermometer and sensor calibration, density and reaction rate measurement. The TV12LT has heated windows keeping them clear and preventing built up of moisture. The window-heating is thermostat driven and kept around 30°C. Without window-heating the window would drop in temperature by the cold bath liquid and condensation would follow.

The TV12LT is based on our latest technology already used in the TV12. The fully ASTM D 445, IP 71 and ISO 3104 bath offers unique figures for temperature stability and overall dimensions. The stainless steel construction ensures exceptionally stable temperatures which are further improved by an ingenious stirring mechanism with baffle plates. All wetted parts are made of stainless steel and PTFE, providing resistance against all usual bath fluids. The bath is fitted with adjustable feet for levelling. The cover of the bath has 4 round 51 mm holes with lids, for suspending glass capillary viscometers in holders. A permanent light is located in the top plate to supply clear light and guarantee optimal visibility inside the bath. The TV12LT has a bath volume of only 12 litres. A bath overflow outlet protects against expanding bath fluid when the bath filling is too high. The bath can be emptied via a drain. If bath fluid expands at higher set point temperatures overflow of bath is protected via a drain. A LED fluid-level indicator alarms when fluid level is too low.

Overall accuracy is better than +/- 0.02°C over the whole temperature range. Ambient temperature drift <0.003°C/°C. The homogeneity is better than 0.02°C.  The TV12LT will be available in 230V/50Hz, 230V/60Hz and 115V/60Hz.
