Overview

The WTW Turb® 430 T 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.

Product Features
  • US EPA 180.1 standard
  • Measuring range comprises 0.02 -1100 NTU/FNU with automatic measuring range switching 
  • AQA: Calibration interval setting and GLP-compliant documentation 
  • Stray light behavior according to pharmacopoeia 5.0 
  • Higly precise AMCO Clear® Standards 

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 put out 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 T 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!

AMCO Clear® standards 

Polymer calibration standards resist against Formazine by notably higher accuracy and stability without drifting, which significantly increases the measuring accuracy:

  • Manufacturing tolerance of only ±1% for highest result accuracy 
  • Long-term stable particle distribution and size 
  • No health hazard 
  • Easy to dispose of N.I.S.T. traceability
