Digital Nephelometer

About Digital Nephelometer

The Digital Nephelometer is a high-precision analytical instrument used to measure the turbidity of liquids by detecting light scattered by suspended particles. It provides accurate and reliable readings in NTU (Nephelometric Turbidity Units), making it essential for water quality analysis in laboratories and treatment facilities.

This instrument is widely used in drinking water plants, wastewater treatment, environmental monitoring, pharmaceutical industries, and research laboratories.

Key Features:

• Digital Display: Clear LED/LCD display for easy turbidity reading
• High Accuracy & Sensitivity: Measures low to high turbidity levels with precision
• Microprocessor-Based: Ensures stable and repeatable results
• User-Friendly Operation: Simple controls with quick calibration
• Compact Design: Space-saving and portable
• Low Power Consumption: Efficient operation for continuous use

Working Principle:

The instrument works on the nephelometric principle, where a light beam is passed through the sample, and the intensity of light scattered at 90 by suspended particles is measured. The scattered light is proportional to turbidity and is displayed digitally in NTU.

Applications:

• Drinking water quality testing
• Wastewater and effluent analysis
• Environmental monitoring
• Pharmaceutical and chemical industries
• Food & beverage processing
• Research and educational labs
