Viscosity automatic characteristics I plant developed by the TN - 7 type test is intelligent instrument designed for intrinsic viscosity determination of chemical fiber products and other high molecular. The main features of this type of machine is the use of microcomputer control and photoelectric reading, automatic judgment and calculation of print results, is a new generation product of chemical fiber products, petrochemical and other viscosity measurement update; with a large screen liquid crystal display, make the operation more simple and intuitive; beautiful appearance; the use of non-volatile devices preservation 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.

Unfortunately, when he was awake when found, he massacred village names including his wife and daughter. The whole work process control by the micro computer, and 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.

Measuring method accord with the national standard GB/T 17931 - 2003.

The precision of temperature control: temperature range of 10 to 120 DEG C, the temperature error of plus or minus 0.01 DEG, 0.01 DEG C display accuracy.
