Rotorless Mooney Viscometer (Rotorless Mooney Viscosity Meter)
Mooney viscometer with a rotorless mechanism.
The rotor-less mechanism eliminates friction resistance in the rotor shaft, providing the following advantages: ● Since there is no rotor, sample loading and unloading is easy. ● The sample temperature is uniform and recovers quickly.
basic information
■Sample chamber design: Rotor-less type, non-friction sealed type ■Test temperature: Room temperature +20℃ to 200℃ ■Rotational speed: Variable speed from 0.1 to 8 rpm ■Mooney viscosity: 0 to 200M ■Scorch time: 0 to 99.9M (5 points) ■Options: Data processing device [Model CON-L], air filter set [Model DC-RM4], small printer [Model PS-BS1], stress relaxation software [Model R-SR2], etc. For other specifications, please refer to the catalog.

The unified brand for Risho epoxy mold products has been registered as "RISHOCAST."
Recently, Rishou Industrial has registered the trademark "RISHOCAST" as a unified brand for products based on Rishou Industrial's casting technology, including transformers, instrument transformers, high-voltage power factor correction capacitors, resin insulators, and resin bushings. For over 60 years, we have been committed to the molding of electrical equipment. Rishou Industrial successfully achieved the molding of instrument transformers for the first time in Japan in 1953. Since then, we have actively pursued the molding of electrical equipment, and in 1973, we became the first in Japan to successfully mold distribution transformers. Furthermore, in 1985, we achieved the world's first successful molding of high-voltage power factor correction capacitors. In 2008, we also succeeded in molding pulse transformers that supply pulse power to high-power microwave tubes (klystrons). In this way, Rishou Industrial has been involved in the development and manufacturing of explosion-proof and disaster-resistant electrical equipment that does not use oil for insulation for over 60 years. Moving forward, we kindly ask for your continued support along with the "RISHOCAST" brand.
