Portable Turbidity Meter LB-20PTM measures turbidity from 0 to 1000 NTU and suspended solids from 0 to 1000 mg/L using 90° scattered and 180° transmitted light. It uses near-infrared technology and high-precision optics to minimize colour interference and deliver stable, accurate results. Our turbidity meter features a clear OLED display for real-time readings and user-friendly operation.
