Electromagnetic Rotational Viscometer EMS-1000S

EMS viscometer is a new viscosity measurement principle, in which the sample is placedpatentPut another sphere into the sample container.
The measurement of electromagnetic rotating ball viscometer is to observe the viscosity of a liquid by rotating a sphere driven by electromagnetic interaction. Two magnets are connected to the rotor to establish a rotating magnetic field. The sample is placed in a measuring tube with a sphere inside. The test tube is placed in a temperature control room, and the sphere is located at the center of two magnets. The rotating magnetic field induces the formation of eddy currents in the sphere. The generated Lorentz force generates torque between the magnetic field and eddy currents, thereby rotating the sphere. The rotational speed of a sphere depends on the rotational speed and magnitude of the magnetic field, as well as the viscosity of the sample surrounding the sphere. The movement of the sphere is monitored by a video surveillance camera.

Main features of electromagnetic rotational viscometer EMS-1000S:

1. Wide temperature range: 0-200 ° C, ± 0.1 ° C, within 10 minutes (25 ° C → 200 ° C).
2. Wide measurement range: 0.1-100000mPa · s (when using a Φ 2mm sphere).
3. Fast measurement speed: Below 100mPa · s, it takes about 1 second, and 10000mPa · s takes about 1 minute.
4. Evaluable liquidity: shear rate of 0.01~150s^-1Evaluate the flow curve through rotational speed.
5. Extremely small sample size: Standard 300 μ L, optional 90 μ L sample container for viscosity testing.
6. Good airtightness: Sealed test tubes prevent sample evaporation and errors. The sample can be recycled and reused.
7. The operation is very simple: put the sample and sphere into a test tube, and the test tube can be placed inside the instrument for testing.
8. No need for cleaning and maintenance: Use inexpensive and disposable sample tubes and spheres that do not require cleaning after testing.
