Model: ZNN-D8

Standards: API-13B and API-10

Features of 8-speed rotational viscometer

1. Coaxial cylinder rotary viscometer

2. Dial direct-reading data

3. Carrying case is provided as standard, which is convenient for on-site handling and storage

4. It can be equipped with a heating jacket to control the temperature of the test sample

5. Manually press the key to adjust the speed

6. Dial reading magnifier for easy reading

7. Pulse electronic governor is adopted to continuously detect and automatically adjust the speed; Can maintain constant shear rate under different input voltage and shear conditions

8. The threaded rotor is used to ensure that the rotor is stable and not easy to loose and fall during the whole test process

8. The instrument adopts high-precision stepper motor and belt direct speed change, without complex gear speed change mechanism, easy to maintain
