Mooney Viscometer

Mooney viscometer is useful to test the vicosity quality of rubber and plastic. It measures the change in rubber and plastic elastomer over time. That is providing frequency conversion type Mooney Viscometer.

The testing sample is deformed using a rotating platen. Thus, it determines the changing levels of viscosity at the current temperature. After the test is over, dies remove the specimen automatically. The motors give accurate results. Additionally, they are easy to use and quiet. Moreover, they do not require any maintenance. Thus, you save costs. The Mooney Viscometer is comes with modular electrical boards. Dies that are easily detachable. It also has optional calibration visa computer. The instruments ensureses maximum safety as well. This machine is latest in the market.

The unit auto-zeros before each test. It also auto-calibrates viscosity. Furthermore, it does not exceed 2 min and 50 sec when heating from ambient to 100ºC ± 0.3ºC.  While testing the die chamber temperature will be redeemed to the tolerance. Thats is ± 0.3ºC within one minute from die closure. This machine is in accordance with ASTM-D1646, ISO-289,JIS K 6300.
