About Turbidity Meter
The Turbidity Meter is a precision analytical instrument used to measure the clarity or cloudiness of liquids by detecting the amount of suspended particles present in a sample. It provides readings in NTU (Nephelometric Turbidity Units), making it essential for water quality monitoring and treatment processes.
This instrument is widely used in drinking water plants, wastewater treatment facilities, environmental monitoring agencies, and industrial laboratories.
Key Features:
- Digital Display: Easy-to-read LCD/LED screen showing NTU values
- High Accuracy Measurement: Provides reliable turbidity readings for quality control
