Modulus Data Systems was started in 1972 in the heart of the Silicon Valley as pioneers of hospital laboratory digitization.  Our DIFFCOUNT III digital differential cell counters are designed for use in any clinical laboratory. While automated hematology instruments can differentiate to three or five parts, the DIFFCOUNT III can manually tally and store up to 12 differentials in its memory, making it an essential tool for today’s laboratory. 

The DIFFCOUNT III is available in 8 or 12-key models, with additional models allowing communication to a host computer system or printer.
