I plant developed by the YN - 7 type viscosity automatic testing, is based on the YN - 6 type on the further design of. The main features of this type of machine is on the valve Lu and software are improved, so that the oil sample can't pass electromagnetic valve and discharged directly into the waste liquid bottle, so you can test the high viscosity of the oil sample, can carry out timing and automatic calculation of sample viscosity. Completely solve the oil sample valve road blockage problem; 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 and more accurate 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 products are widely used in petroleum, chemical industry, scientific research, measurement and other departments.

This product is a high precision testing instruments for fully automated testing of Newton fluid viscosity, completely solve the man-made errors in measurement, high labor intensity of manual cleaning and drying of glass capillary, low productivity and damage of capillary problems, working process is fully automatic, namely: constant temperature, sample test, timing, alarm, cleaning, drying, print test results, automatic calculation of sample viscosity. The whole working process is controlled by micro computer, and a fault identification, error message output and fault treatment ability.

The instrument adopts the Ubbelohde capillary viscometer and improved Buchanan fenci Ke - countercurrent type viscometer, of transparent and opaque and black oil like liquid automatic test; a machine can be two kinds of sample and test, test, the use of high efficiency, low operation cost; a person can perform multi machine operation, and can be connected with laboratory microcomputer system; wide measuring range, in line with the 265-88 standard and ASTM standard national standard GB/T D445.

Measuring method accord with the national standard GB/T 265-88, the precision standard conforms to the JJG155-91 standard.

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.
