Turbidity & Suspended Solids Probes and Meters
LAR LLC Provides Turbidity and Suspended Solids Probes and Meters for a Variety of Industrial and Municipal Applications
Turbidity and Suspended Solids are both measures of water quality. Turbidity measures side-scattered light in relatively clean water in Nephalometric Turbidity Units (NTU). In dirtier water, suspended solids measures light extinction across a gap in Grams per Liter (g/L).
From low-range turbidimeters for drinking water to durable, high temperature, industrial Suspended Solids probes, LAR LLC is likely to have a turbidity or suspended solids system to match your needs. Browse by measuring range and features to find the system that's right for your application.
