| Online Optical DO Sensor DO is one of the significant standards of the water's self-purification. Based on fluorescence quenching, Our ODO sensor can calculate DO amount in water accurately with our own sensor membrane. ODO sensor which based on fluorescence method doesn’t consume oxygen, can’t be disturbed by sulfide and water flow, besides, stirring is absolutely unnecessary. Advantages: Less maintenance Real-time online data transmission, self-cleaning brush and temperature’s auto-compensation, decreases the necessity of manual manipulation severely. High stability, high accuracy Comparative circuit and optical system which designed for the probe solved the problem of parts-aging, in this way, the probe can work accurately and stably. Cap works longer Fluorescence reaction consumes less energy, and the sensor cap can work one year long. |

| Online 4-electrode Conductivity Sensor Conductivity sensor is widely used around power sector, chemistry industry, environmental protection field, food safety field and marine studies. Our sensor increases a pair of driven electrodes, which can effectively avoid deviation and drift caused by polarization of electrode. Besides, we designed the conductance cell inside the sensor, so the maintenance intervals are much longer. Advantages Quick response, accurate measurement, reliable values, easy to handle; Very weak signal can be measured, no polarization; Wide range, medium and high conductivity are easy to measure; Smooth surface, rare fouling, easy to clean; Automatic temperature compensation; PEEK, sturdy and durable, wide scope of application. |

| Online Chlorophyll Sensor hlorophyll in various forms is bound within living cells of photosynthetic organisms, such as phytoplankton and blue-green algae. The amount of chlorophyll found in a water sample is used as a measure of the concentration of phytoplankton. These measurements contribute to the understanding of the general biological “health” of the system. Chlorophyll measurements can also identify algal bloom events and their effects on water quality and anticipate toxic algal blooms. Chlorophyll fluoresces when irradiated with light of a particular wavelength (435-470 nm). For field measurements, BroadSensor fluorometers induce chlorophyll to fluoresce by shining a beam of light of the proper wavelength into the water and then measuring the higher wavelength light which is emitted. These real-time chlorophyll measurements complement extractive lab analysis. Advantages: Digital Sensor, Output 485, Modbus; Useable on Online Multiparameter Water Quality Sonda; High sensibility; quick response; high stability; low power consumption; easy to operate and maintain. |
