The DS500 is an in-situ water quality sonde based on advanced sensor technology. It can be used portably in the field or deployed long-term for online monitoring of various parameters, including temperature, depth, conductivity (specific conductivity, salinity, TDS, resistivity, density), pH, ORP (oxidation-reduction potential), dissolved oxygen, turbidity, chlorophyll, blue-green algae, oil in water, ammonium ions, and more. With a compact diameter and a wide range of measurement parameters, it is widely applicable in various water quality testing scenarios, including marine, surface water/groundwater, aquaculture, environmental protection, and water supply and drainage.

The DS501 is equipped with five sensors and one electric cleaning brush. It is an in-situ water quality sonde based on advanced sensor technology. It can be used portably in the field or deployed for long-term use to conduct online monitoring of parameters such as temperature, depth, conductivity (specific conductivity, salinity, TDS, resistivity, density), pH, ORP, dissolved oxygen, turbidity, chlorophyll, blue-green algae, oil in water, and ammonium ions. With a wide range of measurable parameters, it can be widely applied to various in-situ water quality testing scenarios in the ocean, surface water/groundwater, aquaculture, environmental protection, water supply and drainage.

The DS502 is equipped with six sensors and one electric cleaning brush. It is an in-situ water quality sonde based on advanced sensor technology. It can be used portably in the field or deployed for long-term use to conduct online monitoring of parameters such as temperature, depth, conductivity (specific conductivity, salinity, TDS, resistivity, density), pH, ORP, dissolved oxygen, turbidity, chlorophyll, blue-green algae, oil in water, and ammonium ions. With a wide range of measurable parameters, it can be widely applied to various in-situ water quality testing scenarios in the ocean, surface water/groundwater, aquaculture, environmental protection, water supply and drainage.

The DS-ISA in-situ full-spectrum online water quality analyzer utilizes the UV/Visible light range (190-840 nm) to simultaneously detect multiple parameters in water, with a single measurement covering the absorption spectrum across the entire wavelength range. Compared to electrochemical sensors and multi-parameter measuring instruments, the DS-ISA is a more comprehensive measuring device. Through calibration, the DS-ISA can be adapted for a wide variety of applications. Additionally, the adjustable optical path length enhances the range, accuracy, and resolution of the DS-ISA, thereby expanding its application scope.
