The measurement accuracy was evaluated to be the best at the Olympic demonstration among products of six companies in 2010.
This was also evaluated to have excellent measurement accuracy at the Olympic demonstration in 2012.
Please see the observation examples. We will also visit for a demonstration so that you can confirm the performance.

Development and production are completely carried out in Japan, and both customization and after-sales service are ensured.
Our original lighting technique provides a uniform background within the measurement area for both bright and dark fields.
It selectively counts individual colonies even while taking into account subtle differences between culture medium and colony.
The following is a result of ununiform brightness in a petri dish confirmed by us.
PSF-1000 type has a sufficient uniform brightness to count a colony, and the PSF-2000 type has even more uniform brightness.
The software contains two measurement modes: one is to measure different types of colonies for research and the other is to measure a large amount of the same type of colonies for quality control and these modes can be switched for use.
While displaying a live image, the brightness of the image and the threshold value for extraction of only a colony can be adjusted to set up the optimal measurement condition for counting colonies. It is suitable for counting different types of colonies during each measurement. It is easy and intuitive to operate, and respective measurement conditions can be saved and retrieved at any time.
The optimal measurement condition for each colony type can be set in advance. This mode is suitable for measuring a large amount of the same type of colonies. Detailed settings for measurement conditions are available according to the following treatment in simple mode.
To separate a colony from a culture medium, the monochrome conversion method with optimal contrast can be selected. (Standard mode only)
The higher the contrast is between a culture medium and a colony, the higher the degree of precision for measurement. In the case of the left image, monochrome conversion with G-component extraction provides a higher degree of precision for measurement than simple monochrome conversion.
Low-cost colony counter with minimum necessary functions for measuring colonies
All-round type not only for research and inspection but also for various culture media.
* PSF-3000 is equipped with general-purpose binalized image processing software as a standard. (Various values such as area of colony, average of size and standard deviation value can be calculated.)
