Purpose
The SGZ series turbidity meter is used to measure the scattering degree of light generated by insoluble particulate matter suspended in water or transparent liquids, and can quantitatively characterize the content of these suspended particulate matter. This instrument is calibrated using the Formazine turbidity standard solution specified in the international standard ISO7027, and NTU is used as the turbidity measurement unit.
It can be widely used for turbidity measurement in power plants, water treatment plants, domestic sewage treatment plants, beverage plants, environmental protection departments, industrial water, liquor and pharmaceutical industries, epidemic prevention departments, hospitals and other departments.

Instrument Features
Adopting an LCD display with backlight makes reading more comfortable and not affected by natural light.
Simple operation, appropriate measurement range, and high cost-effectiveness make it more suitable for use in various industries.
The unique positioning structure and high-precision optical path system effectively ensure the accuracy and repeatability of measurement values.
By adopting a low drift, high-precision, and stable circuit system, as well as an efficient and long-life light source, the instrument can effectively ensure long-term stable operation.
The instrument can be powered by AC/DC, with a low-power configuration and a compact and lightweight design, making it easy to use in the field or laboratory.
The instrument is equipped with a low voltage indicator function, which instructs the user to replace the battery to ensure accurate and effective measurement values.
