The model AS16-BT-N is a high-precision, single channel absorption probe. This stainless steel probe, equipped with a BBI safety port, is designed for use in vessels or inline applications.

The AS16-BT-N uses the light in the near infrared range (NIR). A precisely defined, constant light beam penetrates the process medium. The attenuation ofthe light intensity, caused by absorption and/or scattering by dissolved and undissolved substances, is detected by a hermetically-sealed photo diode.

The optical filter on the lamp side adapts the wavelength for specific applications and allows color insensitive concentration measurements in the near infrared range.

The probe is available in six different optical path lengths (OPL), from 1 to 40 mm. The AS16-BT-N is also available with a 100 mm extended insertion depth for largervessels (e.g. fermenters).

The seal-less, sapphire window design eliminates crevices and gaps to assure the highest level ofsterility, cleanability and sensor integrity. The probe body demonstrates extreme durability and fulfills the CIP/SIP requirements demanded by ultra-sanitary process environments.

NIST-traceable validation accessories are available as option to provide absolute measurement confidence.
