BLh300R High-power Remote-controlled Agitators with External I/O

The BLh-R Series is a remote-controlled type agitator that allows control from an external source.

The series utilizes a high output 70W brushless motor that was developed to handle demanding agitation situations.

These strong laboratory agitators generate twice the torque of the BL-R series.

Using the external output of the rotation speed and converted torque, the agitating situation can be understood. Then depending on the agitating condition it is possible to control the rotation speed and switch the rotation direction through inputting from an external source, allowing the instrument to be used as part of an agitation system.


  • Because the rotation speed and conversion torque values are output as analog voltages, it will be possible to identify changes in viscosity.
  • The rotation speed setting and rotation direction switching can be operated through inputting from an external source.
  • During the agitating operation, one-switch operation allows the rotation direction to be changed, and the timer allows automatic forward/reverse rotation agitating to be carried out.
  • During the agitating operation, even if there is a change in the viscosity, the set rotation speed will be maintained.
  • A strong brushless motor is used that does not generate sparks, and the motor part is maintenance-free.
  • A collet-type hand tightening chuck is utilized, and noise countermeasures are implemented to prevent mis-operation of the instrument or other equipment.
  • For the overloading protection of the agitation motor, protection equipment including a current restricting circuit and thermal protector are provided.
