| Abstract: | An automatic capillary viscometer with photo fibers as the cold light source and a thermostate which maintains con stant within ±5×10-4℃ has been developed, giving an accuracy of ±4×10-3 sec. for determinating the time of flow in this capillary visco-meter. In this paper, the basic principle, construction, specifications and main features of this instrument were described. |
