TN-8 automatic viscosity tester
Full automatic characteristic viscosity tester developed by this factory TN - 8 type intelligent instrument designed for intrinsic viscosity determination of chemical fiber products and other polymer materials. The main feature of this model is in accord with the national standard GB/T 17931-2003, microcomputer control, photoelectric reading, automatic judgment and calculation results is a new generation product printing, chemical fiber products, petrochemical and other viscosity measurement update; with a large screen liquid crystal display, make the operation more simple, intuitive; beautiful appearance; the use of non-volatile devices save the temperature compensation value and the test of historical records, so just a temperature on the temperature compensation point of the measured, overcome the original frequent proofreading, more precisely on the constant temperature system adopts the PID control so that the temperature is more stable, measurement. The products were awarded the Petrochemical Corporation scientific and technological progress awards, and won the two prize of the people's Government of Fujian province science and technology.
The instrument adopts the two at the same time test mode, improve work efficiency; testing process full automation, and high test accuracy. Completely solve the man-made errors in measurement, high labor intensity of manual cleaning and drying of glass capillary, low productivity and damage the capillary problem. The working process is fully automatic, including: constant temperature, sampling, testing, timing, alarm, cleaning, drying, print the test results, the automatic calculation of intrinsic viscosity values of samples etc.. The whole working process is controlled by micro computer, and a fault identification, error message output and fault treatment ability.
The instrument adopts special Ubbelohde capillary viscometer, a machine can be two kinds of samples tested at the same time, the use of high efficiency, low operation cost. A person can perform multi machine operation, and can be connected with the lab computer system.
