The Tamson TV-Series viscometer baths are developed for use in laboratories where stability and precision of equipment are essential. With the TV2000AKV system it is possible to determine viscosity in a way which complies with the ASTM method D445 and D446. The measuring head is suited to measure both transparent and colored / darker liquids. Via the apparatus menu the sensitivity of the electronic detection system can be adapted. The measuring head can store up to ten viscometer tube constants. It is further possible to set the amount of runs (test) per sample. The system determines the best reproducibility from the measuring results. Working temperature span ranges from ambient temperature +5°C, up to 130°C. With the use of the cooling circulator TLC15 and the built in cooling coil the minimum working temperature can be lowered down to 10°C however due to condensation it is not advisable to work for long periods at these temperatures. The viscosity measurement range is defined by the used glass capillaries and may vary from 0.3 up to 10.000 cSt. The working temperature can be set in steps of 0.1°C. Overall temperature stability is ± 0.01°C*. With the offset function the temperature reading can be trimmed with a resolution of 0.01°C. Viscosity can be determined by measuring the time the sample needs to slow through a defined length of capillary. This time is in the AKV-system measured via two optical IR sensors. Time, capillary constant and bath temperature result in a viscosity value given in centi Stokes (cSt). The AKV system is semi-automatic which means that the sample has to be put manually into the glass capillary tube. After the measurement the viscometer tube needs to be cleaned thoroughly. The AKV systems offers the choice to use either Ubbelohde or Cannon-Fenske viscometer tube. For both types a specific measuring head is available. Though the AKV offers the possibility to measure colored / darker liquids, some dark fluids can give difficulties with the optical detection. A sample always can be send to us for testing without costs.
