The first OEM CO2 monitor with 32 bit digital signal processing stability and accuracy

Description

The Model 300 combines cutting edge 32 bit digital signal processing with the solid reliability and compact size that characterize Digital Control Systems' OEM products. State of the art microprocessor technology makes this full-featured CO2 measurement subsystem less complex and more robust than previous generations of instrumentation. Its so reliable we back it up with an unprecedented two year warranty; twice the industry standard.

Advanced design provides a very stable, drift-free output requiring less frequent calibration. Your customer will appreciate having an incubator that saves on CO2 costs and provides tighter control over concentration levels in the chamber.

The Model 300 is designed for demanding OEM applications that require sophisticated performance in a compact format at a competitive price. It provides a stable, drift-free linearized voltage or current output that is much less susceptible to external electro-magnetic interference than conventional analog electronics. With power consumption as low as 125 mA (average) and a control board that occupies less than 16 square inches , this powerful measurement subsystem is easily incorporated into a broad range of products.

The sensor assembly is cable connected to the control board for mounting convenience and can be used with diffusion or pumped sample draw systems. An optional remote calibration control and digital readout showing concentration to the nearest 0.1% are also available.
