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.

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.

Online Blue-green Algae Sensor
近年来,经常会看到鱼类大面积死亡的新闻,导致此类事件发生的原因之一就是绿潮或赤潮的大规模发生,也就是水域内富营养严重,导致蓝绿藻疯狂生长,进而堵塞鱼鳃,使其无法呼吸。更严重的话就会影响地表水乃至饮用水的安全,破坏生态平衡及公共健康。
蛙视通过荧光分析法来监测蓝绿藻的含量。该方法直接检测蓝绿藻细胞中特定色素的荧光物质,以确定相对的藻类毒素。传感器采用IP68防水处理,支持Modbus。可长期广泛应用于河流、湖泊、养殖业、饮用水源地等领域。

光学PPB溶解氧传感器
蛙视新一代ppb溶解氧传感器,基于荧光猝熄原理,蓝光照射到荧光氧分子探针上激发出红光,由于氧分子是荧光探针的猝熄剂,氧分子可带走能量,所以激发出的红光的时间和强度与氧分子的浓度成反比。溶解氧传感器通过测量受激发的红光和参比光的相位差,并结合温度补偿后的3D标定数据模型,计算出氧分子浓度。
