ATL Turbidity Probe

Brand: KOBOLD Instruments, Inc.

ATL-F
The Kobold Turbidity Probe ATL-F is a high-precision, single channel absorption probe. The probe uses the light in the visible (VIS) range at a selected wavelength of 430 nm. An optical filter on the lamp side adapts the wavelength for specific applications and allows colour measurements with great accuracy (e.g. phase separation beer/water) at 430 nm.

ATL-N
The Kobold Turbidity Probe ATL-N is a high-precision NIR single channel absorption probe. The ATL-N uses light in the Near Infrared (NIR) from 730 to 970 nm. The optical filter on the lamp side adapts the wavelength for specific applications and allows colour-insensitive concentration measurements in the near infrared range. The ATL-N probe comes with two different optical path lengths (OPL) for process versatility.
