ZD-2A Portable Scattering Light Turbidimeter

The ZD-2A portable turbidimeter is a practical water quality testing instrument used to measure liquid turbidity in NTU. It adopts the 90° scattered light measurement principle, helping users evaluate the clarity and suspended particle level of water or liquid samples.

This scattering light turbidity meter is suitable for water quality detection, sewage disposal, environmental protection, liquor making, pharmaceutical industry and scientific research. The compact handheld design makes it convenient for on-site testing, while the backlit display allows users to read results more clearly in different working environments.

The ZD-2A supports both battery power and plug-in power, making it flexible for field inspection, laboratory work and routine water quality monitoring. With simple key operation, microcomputer control, wide measurement range and stable performance, it is a reliable choice for daily turbidity testing.
