Optical probe / stainless steel / insertion

The ASD12-N, ASD19-N and ASD25-N absorption sensors are designed for use in pilot and production scale fermenters or bioreactors to precisely measure the growth of microbial or cell cultures as a function of NIR absorption.
NIR-Absorption

A precisely defined and constant LED light beam penetrates the process medium. ASD12-N, ASD19-N and ASD25-N use light from 840 nm to 910 nm (NIR). The attenuation of the light intensity, caused by absorption by dissolved substances and undissolved material is detected by a hermetically sealed photodiode.
ASD25-N / ASD25-BT-N

Models ASD25-N and ASD25-BT-N are designed for use in pilot or production scale fermenters or bioreactors. These extremely durable probes are designed for sanitary bioprocess environments and can be used in CIP/ SIP processes.

The ASD25-N is conveniently mounted through a standard 25 mm Ingold ?type port and the ASD25-BT-N through a standard 25 mm safety port.
