The WTW Turb® 430 IR Portable Turbidity Meter provides turbidity measurement accuracy to DIN ISO 27027 standard for any demand up to 1100 NTU.
The WTW Turb® 430 IR Portable Turbidity Meter meets the requirements of nephelometric measurement at 90° stray light for drinking water with highest precision particularly suitable in the range < 1 NTU. It is therefore suitable for water analysis and control, fuel, cell cultures, food and beverage industries and health administration surveillance.
The measurement and automatic 3-point calibration runs menu-guided. The calibration takes place via an AMCO Clear® standard set (0.02-10-1000 NTU). Up to 1000 data sets including sample ID numbers can be stored and later output GLP-compliant via the PC software LSdata.
The quality assurance of the measured results is supported by calibration interval setting with documentation. This makes the WTW Turb® 430 IR Portable Turbidity Meter not only a portable instrument – also available in a practical field set - but also a precise and reliable benchtop meter for applications of up to 1100 NTU/FNU with optimized data administration!
Polymer calibration standards resist against Formazine by notably higher accuracy and stability without drifting, which significantly increases the measuring accuracy:
