A new multi-parameter water quality sensor designed for portable monitoring of diverse water bodies, including surface water, groundwater, source water, sewage outlets, drinking water, and marine environments. It supports deployment at depths up to 200 meters, features a hot-swappable design, compact size, light weight, and excellent portability.
Water Quality Parameters:
Dissolved Oxygen (Optical),Turbidity(SS, transparency),pH/ORP,Conductivity(TDS, Salinity),Chlorophyll,Temperature,Depth,Nitrate,Ammonium,Potassium.


·Supports 200-meter depth applications with a full titanium alloy housing;
·Main body diameter <50mm, suitable for groundwater monitoring, installation in confined spaces, and portable use;
·Built-in pressure sensor for liquid level/water depth measurement;
·Optional configuration with or without a cleaning brush;
·Multiple material options (aluminum, stainless steel, titanium alloy) to adapt to various complex environments;
·Low power consumption: standby current <1mA, operating current <50mA;
·Can connect up to 4 Linksens 16mm sensors simultaneously with automatic identification.
