The PIK-GEOVIS-700 capillary viscometer makes it possible to measure viscosity of single phase fluid or liquefied gas samples in temperature and pressure conditions, in accordance with GOST 7163-84, by solving the Hagen-Poiseuille equation based on the pressure drop while fluid or gas goes through the capillary vessel and having familiar data. The unit is supplied with a set of three capillary tubes measuring viscosity ranged from 0,1 MPaˑs to 10000 MPaˑs.

Sample supply is carried out with a syringe pump ensuring the required pressure and flow stability through a capillary system together with the measuring of pressure drop along the capillary. Herewith the phase under study is constantly inside the temperature-controlled volume, which improves measurement accuracy and secures the reliability of received data.

Accuracy of the received results is also guaranteed by the calibration function in the PIK-GEOVIS-700 capillary viscometer.
