LH-NTU3M200 Turbidity Meter

Product Introduction
The LH-NTU3M200 Turbidity Meter is a digital water quality analyzer designed for accurate turbidity measurement from 0 to 200 NTU. It uses the 90° scattering method to reduce interference from water color and provides direct digital readings through a microcomputer processing system.
Equipped with an LCD display, built-in calibration function, large data storage capacity, printer, USB interface and infrared data transmission, the LH-NTU3M200 provides an integrated solution for laboratory and routine water turbidity testing.

Performance Features
• 90° scattering method: Reduces the influence of water color on turbidity measurement.
• 0–200 NTU range: Designed for accurate measurement of water samples within the specified turbidity range.
• Microcomputer processing: Processes measurement signals and directly displays turbidity concentration.
• Clear LCD display: Simple and intuitive operation.
• Large data storage: Stores up to 5,000 measurement records for convenient review.
• Date and time display: Records measurement information with year, month and day.
• Built-in calibration: Supports instrument calibration for routine operation.
• Integrated printer: Prints current measurement results and stored historical data.
• USB data transfer: Transfers stored historical measurement data to a computer.
• Infrared transmission: Provides an additional method for transmitting stored measurement data.

Working Principle
The LH-NTU3M200 uses the 90° scattering method for turbidity measurement. A light beam passes through the water sample, and suspended particles in the sample scatter the incident light.
The detector positioned at approximately 90° to the incident light measures the scattered light intensity. The microcomputer processing system converts the optical signal into a turbidity value and displays the result directly on the LCD screen.
The 90° scattering configuration helps reduce the influence of sample color on the measured turbidity value. The instrument uses an internal calibration curve that can also be adjusted by the user when required.
