Consist of polymer microspheres suspended in a pure, aqueous medium
Uniform in particle size distribution to ensure consistent light scattering and precise enough to permit calibration down to and including 0 NTU
Primary turbidity standards for use in 90° nephelometers such as the 2100A, On-line instruments.
Ready to use — no mixing or dilution required
Nontoxic and won't settle out of suspension
Designed for 90° white light turbidimeters (EPA 180.1 design).
Guaranteed accuracy within 1%.
Equivalence Turbidity Standard is packaged in plastic case with a visual comparison card.
Polystyrene technology allows longer shelf life.
Tube size is 15 x 103mm and fits in most spectrophotometers.
