product description

TRA-99Transparency analyzer is an intelligent instrument based on optical measurement principles, which consists of sensors and controllers. Suitable for small water stations, surface water, river sections, urban inland rivers, black and odorous water bodies, lakes and reservoirs, municipal sewage, seawater monitoring, sewage outlet monitoring, aquaculture water monitoring and other applications.

Product principle

This transparency meter is based on the principle of visible light absorption measurement, using a single light source and dual detectors, which can effectively eliminate the interference of external environmental light and suspended solids, and quickly reflect changes in water bodies. Compensating for the shortcomings of visual judgment required by methods such as lead type and Scherrell disk, it can scientifically, accurately, and continuously measure the transparency of water bodies online.
