Tamson Instruments Specification sheet Specifications TV7000LT Tamson Visibility bath 70 Litres Low Temperature - ASTM D445 Used materials inside bath Standard C,F on request Reading Setting Depth bath Top lid stainless steel Integrated cooling High precision better than ± 0.02°C Large windows, no condensation Easy to operate RS232 communication Bath volume Noise level General The TV7000LT is a unique visibility bath with wide dimensions. Span The bath temperature can be set from -40°C to a maximum of +100C in steps of 0.01°C. An integrated cooling system is able to lower the bath temperature down to minus 40°C within approximately four hours. The cooling power is controlled over four stages, so that the heat removal capacity is trimmed to the desired set point temperature, saving up to 50% of energy. Accuracy 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. Drift, accuracy and homogeneity were measured with methanol as bath medium and are true min-max values found over eight hours. Due to its wide temperature range the bath can be used for multiple purposes varying from sub-zero temperature viscosity determination to calibration of sensors or thermometers. The large windows show the bath contents clearly. The windows are heated preventing build-up of condensate. 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. Safety The bath conforms to CE regulation. Further it is equipped with multiple safety features in order to guarantee safe around the clock operation. A mechanical safety thermostat protects the bath against high temperatures and will automatically reset itself after switching the bath off and on again. In case of over temperature electronics and motor are switched off. The pump motor is protected against mechanical overload via a resettable fuse.
