Key Features

1. LCD Speed Display

The integrated LCD screen displays both:

• Set speed
• Actual speed

This provides clear monitoring of the stirring process and allows users to observe operating conditions conveniently.

2. DC Permanent Magnet Motor

The OPX-254 uses a DC permanent magnet motor designed for:

• Low-noise operation
• Stable performance
• Reliable continuous operation
• Reduced maintenance requirements

3. Automatic Safety Stop

The overhead stirring system is designed with an automatic stop function to help enhance operational safety and protect the equipment during abnormal operating conditions.

4. Stable Start-Up

Controlled start-up helps gradually accelerate the stirring operation, reducing sudden movement and helping to minimize sample overflow or splashing, particularly when working with larger volumes.

5. Parameter Memory

The instrument can automatically memorize the final set working parameters, allowing convenient continuation of routine operations without repeatedly entering the same settings.

6. Multi-Segment Programming

The OPX-254 supports multi-segment programming control, allowing users to establish different operating conditions within a programmed mixing process.

This is useful when an application requires different stirring speeds or operating stages.

7. Wide Speed Range

The stirring speed can be adjusted from 100 to 2000 rpm, providing flexibility for low-speed mixing as well as higher-speed applications.

8. High Torque Performance

Depending on the selected model, maximum torque is available up to 30 N·cm, allowing the instrument to handle progressively higher-viscosity materials.
