Stirrer RW 28 digital

Stirrer RW 28 digital

Powerful, mechanical laboratory stirrer for highly viscous media for quantities up to 80 L(H2O). The stirrer is suitable for intensive mixing of samples in laboratories and pilot plants. The stirrer is equipped with an overheating protection of the motor by a temperature limiter. In addition, a stirrer shaft protection and a stand mounting is optionally available.
- Digital display of the speed
- Infinitely variable speed in two speed ranges
- Stirrer shaft insertable
- Overload protection
- Error code display
- Robust, ergonomic design
- High running smoothness
- With constant power drive
