Hanna Instruments HI 300N - Manual (Page 2)

3 2
The Hanna series of magnetic stirrers are
designed with simplicity of use for stirring
and mixing solutions in a wide range of labo-
ratory applications. Several models are avail-
able in an extensive range covering:
• general purpose stirrers
• dual-speed range
• auto-reverse cycle stirring
• rpm indication
• timer control
All models employ a motorized magnet to
rotate a stirring bar to create a forced vortex
rotational flow in the solution with a constant
angular speed which is adjustable with an
external speed knob.
Unlike conventional stirrers, all Hanna stirrers
use the concept of pulse-driven drive to give
the full power required to effectively stir the
fluid regardless of the speed.
This eliminates the need to start the motor at
high speed and the user is now able to
control the speed precisely.

Thank you for choosing a Hanna product.
Please read this instruction manual carefully before

mation, do not hesitate to e-mail us at

These meters are in compliance with directives.
