Portable Turbidity Meter for Laboratory and the Field. Features: • With the turbidimeters Turb 430 IR 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 measure ments in the lower range, e.g. in drinking water are no problem! • Menu driven calibration with up to 3 points and all measure ment function are easy for even the most inexperienced operator to perform accurate and precise measurements. • The calibration is via an AMCO® standards set (0.02-10-1000 NTU). • Up to 1000 data sets with ID nos. can be stored and subsequently output via the LabStation in combination with the powerful LSdata software. • 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: Field case and rechargeable battery set. • Scattered light characteristics according to Pharmacopoeia 5.0 • Multifunctional LabStation • GLP/AQA conform documentation Specifications: • Measuring principles: Nephelometric (90° scatter) • Light source: Tungsten lamp • Measuring range: - NTU: 0 … 1100 - FNU: 0 … 1100 • Resolution: - 0.01 from 0.00 … 9.99 - 0.1 from 10 … 99.90 - 1 from 100 … 1100 • Accuracy: 0.01 NTU or ±2 % of the measured value • Reproducibility: <0.5% of the measured value or 0.01 NTU/FNU • Calibration: Automatic 3 point calibration • Response time: approx. 7 seconds • Cuvettes: 1.10x2.36 in.
