Please note:

As floating and moving particles are measured in turbidity, slight measurement deviations are possible. In order to achieve results that are as representative as possible, attention should be paid to the following:
samples should be measured immediately, as particles otherwise settle.
constant lamp operating temperature.
condensation on samples should be avoided.
the position of the standards should be marked to exclude the influence of glass inhomogenities.

High precision standards:

The supplied polymere standards (AMCO Clear®) are retraceable to formazine standards and rated to be a primary standard according to US EPA. Due to production accuracy, and stability in solution the calibration and the resulting measured values are more precise.

Portable Turbidity Meters

Turb® 430 IR/Turb® 430 T – Lab accuracy & comfort in portable field instrument

  • Scattered light characteristics according to Pharmacopeia 5.0
  • Multifunctional LabStation
  • GLP/AQA conform documentation

With the turbidimeters Turb® 430 T and Turb® 430 IR, the user has the choice to perform nephelometric measurements at 90° scattered light, according to the application and standard required.
The Turb® 430 IR meets the DIN 27027/ISO7027 requirements, the Turb® 430 T those of US EPA 180.1. The measuring range is from 0 to 1100 NTU/ FNU and is identified automatically. Accurate measurements in the lower range, e.g. in drinking water, are easily achieved.
All measurements and menu driven 3-point calibration along with the easy functions for accurate and precise measurements require minimal training. The calibration is performed via an AMCO Clear® standards set (0.02-10-1000 NTU). Up to 1000 data sets with ID numbers can be stored and output using the LabStation and powerful LSdata software.
The quality of the measurement results is supported by adjustable calibration intervals with documentation.
The Turb® 430 is not only a field measuring instrument (especially with the practical field case), but also a “small lab instrument” for applications up to 1100 NTU/FNU and with optimum data management.
Optional: single meter, field case with LSdata, accessories.
