Optical Density Instruments

The CEREX™ MAX System

Extreme performance in optical density measurement.

High Performance Specs

MAX continuously calculates optical density and specific growth rate.

Used in laboratory environments...

Our instruments are used internationally for a wide variety of purposes.

...and in commercial industries.

Featuring low optical density all the way to high optical density (0 to 1 OD), the MAX sensor is also independent of aeration rate and impeller speed.


We offer a range of sensor sizes, as well as bench-top and cabinet mount options.
