HGND 211Type fully automaticThe kinematic viscosity tester is used to measure the kinematic viscosity of oil and polymer dilute solutions, and can be widely used in pharmacopoeia, petroleum, chemical, scientific research, metrology and other departments. This instrument combines the advantages of our company and similar products at home and abroad, and implements a new design concept. While measuring the viscosity of Newtonian fluids with high precision, it completely solves the human error in measurement,avoidHigh labor intensity for manual cleaning and drying of glass capillary tubes，The entire working process is controlled by a microcomputer and has fault recognition function, achieving full automation of the working process, including constant temperature, sampling, testing, cleaning, drying, calculation, printing of test results, etcfully automatic.It is an ideal product for the upgrade of the older generation of motion viscosity testers.

This instrument adopts an automatic Ubbelohde capillary viscometer, which can automatically test transparent, opaque, and black oil sample liquids; onetowerThe machine can test and calibrate two types of samples simultaneously, with high efficiency and low operating costs; And it can be connected to the laboratory microcomputer system; Wide measurement range, applyGB/T 265 standard.

Main features

High timing accuracy and wide temperature measurement range for testing

Using imported infrared detection and control components, as well as special protective devices, has improved reliability and stability

■ Automatically clear the residual liquid left in the capillary tube after the last sampling and testing. During sampling, a proprietary slow sampling structure is used to prevent the formation of bubbles during the next sampling and testing, which may affect the accuracy of the test

Adopting a residual air pressure balance structure in the pipeline, after sampling is completed, air pressure balance is carried out without affecting the detection, which improves the accuracy and repeatability of the test

Users can use thermometers with higher temperature accuracy and standard liquids with higher viscosity accuracy to self calibrate the temperature display and viscosity coefficient of the photoelectric detection device of the viscosity meter
