WZB-172 Portable Turbidity Meter
Product Introduction
The WZB-172 Portable Turbidity Meter is designed for measuring water turbidity in laboratory and field applications. Equipped with an 850 nm LED light source that meets the ISO 7027 standard, it uses a combined scattered-light and transmitted-light measurement principle to provide turbidity readings across a range of 0–500 NTU.
The instrument features automatic range switching, automatic zero adjustment, and calibration options for the zero point and up to five calibration points. Its built-in memory stores up to 500 sets of test data, while USB communication supports data collection on a computer. With battery and USB power options and an IP65-rated enclosure, the WZB-172 is suitable for portable water quality testing and routine turbidity monitoring.

Performance Features
• ISO 7027-Compliant Light Source: Uses an 850 nm LED for turbidity measurement.
•  Combined Optical Measurement: Uses scattered and transmitted light, with multi-angle scattered-light detection.
• Ratio Calibration: Supports ratio-based calibration and automatic color compensation.
• Automatic Range Switching: Selects the appropriate measurement range automatically.
•   Automatic Zero Adjustment: Simplifies routine instrument preparation.
•  Flexible Calibration: Supports zero-point calibration and up to five calibration points.
• Average Measurement: Provides an averaging function to help improve measurement consistency.
• Built-In Data Storage: Stores up to 500 sets of test data in accordance with the stated GLP requirements.
•   USB Data Communication: Connects to a PC for data acquisition.
•   Flexible Power Supply: Operates on battery power or USB power.
•  Power Management: Includes automatic shutdown to help conserve battery power.
• IP65 Protection: Provides protection against dust and water jets under specified test conditions.
• Calibration Solutions Included: Supplied with turbidity calibration solutions for instrument calibration.

Working Principle
The WZB-172 uses an 850 nm LED light source and a combined scattered-light and transmitted-light measurement method. When light passes through a water sample, suspended particles scatter and attenuate the light. The instrument detects scattered-light signals from multiple directions and evaluates them alongside transmitted-light information to determine turbidity.
Ratio calibration and automatic color compensation help reduce the influence of sample color on the measurement. The resulting turbidity value is displayed in NTU, with automatic range switching supporting measurements across different turbidity levels.
