PSF-1100 is a low-cost model with the functions necessary for general colony counting.
Automatic counting within 5 seconds
Uniform lighting ensures good measurement accuracy, even if the culture media thickness is uneven, unclear colonies, or residue/sedimentation exists.
Accurate counting can be achieved regardless of colony quantities
Automatic counting with manual adjustment: Add false-negative colonies, Delete false-positive colonies, Exclude area for count (widespread colonies)
3-megapixel CMOS

* 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.
