Portable turbidity meter Turb® 430 IR – WTW Germany

Portable turbidity meter, SKU: 600320, Turb® 430 IR – WTW Germany

• Turbidity measurement acc. To DIN ISO 27027 for any demand up tp 1100 NTU with lab option
  Turb® 430 IR meet the requirements of nephelometric measurement at 90° stray light for drinking water with highest precision particularly suitable in the range < 1 NTU and is therefore suitable for water analysis,control, such, fuel, cell cultures, food and  beverage industries and (health) administration surveillance.

  • Measuring range comprises 0.02 -1100 NTU/FNU with automatic measuring range switching
  • Adjustable calibration intervals 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 Turb® 430 not only a portable meter – 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 significantly higher accuracy and stability without drifting, which increases the measuring accuracy significantly:
  •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
