JJAVD Viscosity Average Molecular Weight Tester_Chengde Jinjian Testing Instrument Co., Ltd

JJAVD Viscosity Average Molecular Weight Tester

The JJAVD Viscosity Average Molecular Weight Tester measure the intrinsic viscosity (η) of the polymer material solution by viscometry, and determine the viscosity-average molecular weight of the polymer material according to the relationship between the intrinsic viscosity and the viscosity-average molecular weight (Mη).

This instrument is an intelligent instrument designed to measure the intrinsic viscosity and viscosity average molecular weight of chemical fiber products and other polymer materials. It can be widely used in chemical fiber products, petrochemical and other fields.

The JJAVD Viscosity Average Molecular Weight Tester is composed of host, controller, constant temperature bath, test frame, glass capillary viscometer and other parts. The instrument adopts touch screen control, automatic suction, automatic reading, automatic judgment and automatic calculation of results, and the measurement accuracy is high. It can be used to test the annual average molecular weight of ultra-high and ultra-high polyethylene molecular weight. The instrument has beautiful appearance, high precision, convenient and quick operation, and can carry out 4 station tests at the same time.

1. Automatic test control

The liquid suction and discharge is automatically controlled by the instrument, which improves the operation accuracy and reduces the inhalation of harmful gases by the operator; the internationally advanced and reliable position sensing device is adopted to adapt to various solutions, automatically identify the liquid position, and automatically start and stop the timing unit , Overcomes the human error caused by the traditional stopwatch measurement, greatly improves the test accuracy, and makes the test results more real and reliable.

2. The temperature field of the bath is uniform and the temperature control accuracy is high

Using the international advanced integrated temperature controller, the temperature control precision is high, the field is uniform, and the interface operation is simple and intuitive.

3. Automatic calculation of test results

The test results are automatically calculated, and important parameters such as viscosity ratio ( ηrel ), relative increase in viscosity (ηsp), intrinsic viscosity (η), and viscosity average molecular weight (Mη) can be obtained at the same time.

4. Powerful data processing software

U disk is used to store the test data, and the storage quantity can be expanded infinitely according to the capacity of the U disk. The test data stored in the U disk is finally imported into the testDMS data management system software, and the data can be post-processed, saved and printed out of the test report.

5. Visualizing the bath, the test process is clearly visible

The bath has an open double-glazed design, the test rack is clearly visible in the bath, the entire test process is clear at a glance, and it has a good thermal insulation effect.

6. The viscometer is convenient to pick and place and easy to clean

With a specially designed test rack, the viscometer can be picked and placed simply by operating the viscometer pick and place device without removing the test rack from the bath.

7. User-friendly interface operation

It adopts large-size full-color LCD touch screen for control and display, which is easy to operate and intuitive to display.
