  • Description



    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
