ASTM D445 Low Temp. Viscosity Baths 40 & 70 litres

Main Characteristics

The TV4000LT and TV7000LT are unique visibility baths with wide dimensions. Working temperature ranges from -40°C up to +100°C. The integrated cooling system is able to lower the temperature of　the bath content down to -40°C within approximately two hours. The　cooling power can be controlled over several stages, so that the heat removal capacity is trimmed to the desired set point temperature, saving up to 50% of energy. Due to its wide temperature range, the bath can be used for multiple purposes varying from low temperature　viscosity measurement to calibration of sensors and thermometers. The large windows show the bath contents clearly. The windows are heated preventing built up of condensate. The maximum temperature　lies around +100°C. Overall accuracy is better than +/- 0.02°C　over the whole temperature range. Ambient temperature drifts <0.003°C/°C. The homogeneity is better than 0.02°C. Drift, accuracy and homogeneousness were measured with methanol as bath medium and are true min-max values found over eight hours. The TV7000LT　can be used to calibrate long thermometers or to calibrate master　viscometers conform to ASTM D2162.
