英文 Introduction
The WGZ-2B Portable Digital Turbidimeter is a high-performance water quality analysis instrument with a wide range of applications. It uses the 90° scattered light principle to accurately measure the scattering of light caused by insoluble particulate matter suspended in water or transparent liquids, and to quantitatively represent the content of these suspended particulates.
This instrument offers multiple measurement ranges, including 0～10, 0～100, and 0～200 NTU, with a minimum resolution of 0.001 NTU. Equipped with a low-power microcomputer configuration and a touch keyboard, it features a backlit LCD screen that can display date, time, measurement values, and units simultaneously. The WGZ-2B also includes an auto-shutdown function and low-voltage indication to save power and remind users to replace batteries in a timely manner.
The measurement range of the WGZ-2B can be manually selected or automatically switched, and it supports 1-7 point automatic calibration to ensure the accuracy of the measurement results. The built-in color compensation system effectively avoids interference caused by sample color, ensuring that the measurement results truly reflect turbidity. Additionally, the instrument is equipped with a long-life light source that can operate for up to 100,000 hours without maintenance and meets the ISO turbidity measurement standards.
The WGZ-2B Portable Digital Turbidimeter is suitable for various fields such as power plants, pure water plants, water treatment plants, beverage factories, environmental protection departments, industrial water use, brewing industries, and pharmaceutical industries. Its portable design and dual power supply (AC/DC) make it flexible for use in both outdoor and laboratory settings.
