Accurate, Reliable Turbidity Measurement for Water Quality Assurance
Portable Turbidimeter ST 200 ensure compliance and protect public health with our range of turbidimeters—precision instruments designed to measure the cloudiness or haze in water caused by suspended particles. Essential for drinking water treatment, wastewater monitoring, environmental testing, and industrial process control, our turbidimeters deliver fast, repeatable results in compliance with EPA Method 180.1, ISO 7027, and USEPA GLI standards.
Engineered for Clarity and Compliance
Our turbidimeters utilize either nephelometric (90° scatter) or ratio (multi-angle) optical technology to detect particles as small as 0.1 µm, providing accurate readings from 0.01 to 1,000 NTU/FNU. Designed for both lab and field use, models range from portable handheld units to benchtop and online process analyzers—each built for stability, ease of use, and minimal maintenance.
- Compliant with EPA 180.1 & ISO 7027 – Choose infrared (ISO) or white light (EPA) optics based on regulatory needs.
- Wide Measurement Range – From ultra-low turbidity in drinking water (<0.1 NTU) to high-solids wastewater.
- Automatic Calibration & Diagnostics – One-button calibration with standards; alerts for bubbles, fouling, or lamp errors.
- Durable Designs – IP67-rated portables for field use; rugged benchtops for daily lab analysis.
- Data Management – GLP-compliant logging, timestamped results, and USB/Bluetooth export on select models.
- Low Maintenance & Long Lamp Life – LED light sources ensure stability and reduce consumable costs.
Trusted Across Water and Environmental Sectors
From municipal water plants verifying filter performance to environmental consultants assessing stormwater runoff, our turbidimeters support regulatory reporting, process optimization, and early contamination detection. Their intuitive interfaces require minimal training, while high repeatability ensures confidence in every reading.
Whether you need spot-check capability or continuous monitoring, our turbidimeters provide the accuracy, reliability, and compliance assurance your water quality program depends on.
See clearly. Measure confidently. Protect water integrity.
