High-precision, non-contact nephelometer for continuous turbidity measurement in accordance with ISO 7027.
The AMI Turbiwell 7027 uses a unique non-contact measurement design that prevents the optical surfaces from coming into contact with the sample, significantly reducing fouling. Combined with heated optics, this design delivers accurate, stable and reliable turbidity measurements over extended periods with minimal maintenance.
The analyser complies with ISO 7027 and operates without consumables or wear parts, making it a highly cost-effective solution for continuous turbidity monitoring. Typical applications include raw water, potable water, cooling water and effluent treatment.
Key Features
- Non-contact design avoids optical surface fouling and eliminates measurement drifts.
- LED light source ensures long life and stable measurements.
- Heated optics prevent condensation effects for accurate results.
- Integrated constant head ensures stable sample flow to the measuring chamber.
- Cost-efficient operation is guaranteed, as no consumables or wear parts are required.
- Manual or automated chamber draining for cleaning.
