The portable turbidity meters Turb 430 IR acc. to DIN ISO 27027 and Turb 430 T acc. to US EPA 180.1 offer nephelometric turbidity measurement from 0-1100 NTU with full lab accuracy providing data logging including AQA and documentation. This makes them ideal instruments for drinking, well and ground water testing to detect even lowest particle contents < 1 NTU. A low detection limit is important particularly for drinking water quality, since particles are carriers of bacteria and viruses.
Additionally Turb® 430 turbidimeters are used in monitoring of surface and river waters, being important e.g. after special events such as flooding resulting in higher turbidity levels, where no ratio measurement is necessary. In the field, the optional field set makes it a mobile lab, unless the most complete instrument photoFlex® Turb - providing photometry, pH and turbidimetry - becomes more convenient . An optional LabStation for easy lab use turns Turb® 430 into a convenient small but powerfull benchtop turbidimeter. Therefore health and environmental institutions as well as water works use it for field and lab measurements at the same time. The GLP compliant PC-software LSdata allows quick data management and documentation, e.g. for tasks regarding EU Water Framework Directive (WFD).
Highly accurate with AMCO Clear® calibration standards
The supplied polymer calibration standards are superior to Formazine guaranteeing higher accuracy and stability due to highly stable particle suspension:
- Manufacturing tolerance of only ±1% for highest result accuracy vs. Formazine with ±7-10%
- Non hazardous and easy to dispose
- N.I.S.T. traceability
