PSF-5100 is a high-end model with a good balance of performance and cost. Ideal for counting small colonies.
PSF-5100L is a model that support Φ150 mm and 144 x 104 mm dishes.
Features
Uniform light source solves slight difference between culture medium and colonies. Necessity of uniform light source over the whole petri dish.
Measurement functions when there is a residue or a sediment.
Automatic delete function for a widespread colony.
Manual adjustment for measurement result.

* Optional software is required to inhibition zone measurement. This software is standard only in PSF-7100W.
** For square petri dishes, use one that is smaller than the maximum count area.
*** It is possible to change the height position of the top lighting. By this function, the outline of colonies can be clearly photographed.
