Photometric Converter Fermenter Control

Fermenter Control Photometric Converter


The FERMENTER CONTROL photometric converter is specifically designed to integrate easily into existing bioreactors and fermentors. Using input from one or two optek ASD-series photometric probes, the Fermenter Control precisely measures cell growth/biomass as a function of Near Infrared (NIR) absorption. The results are displayed in any laboratory unit, such as OD, AU, Cell Count or Cell/ml. Noise-rejection signal processing feature provides stability and measurement reliability even in systems with a high degree of aeration and agitation.

The intergrated, four-channel Datalogger stores measurement results in user-selectable time intervals. Actual results and the trend can be displayed simultaneously. Set-points, tables and parameters can be stored and even changed by remote I/O. The data can also be transferred to a PC for further analysis.

Three independent set points as well as one or two mA-outputs (4-20 mA) and one or two voltage outputs (0-10 V) are available for alarm and monitoring. An additional relay output (FAIL-SAFE) is built in for remote sensing of lamp or power failure.

Other features include a 240 x 128 pixel display, three-level password protection and multiple languages. The FERMENTER CONTROL is panel-mountable, and is optionally available in a benchtop case for laboratory-scale applications and for portability. A 115/230 VAC or 24 V AC/DC power supply is available.
