Product Description
OSA - Cyano series online Water Analyzer is specially designed for measuring blue-green algae content in the water, which makes use of special fluorescence effect of the phycocyanin or phycoerythrin from blue-green algae for tests. It stimulates blue-green algae in water sample with high brightness and special wavelength LED to make the phycocyanin or phycoerythrin from blue-green algae emit fluorescence accordingly, and then its high sensitive photoelectric sensor will catch weak fluorescence signal and convert this signal into density value of blue-green algae, meanwhile, this device adopts digital and intelligent sensor design concept, being able to automatically compensate voltage fluctuation, device aging and temperature change effect on the measured value. It outputs standardized digital signal directly and achieves network and system integration without a controller.
Product Features
♦ Use high performance LED as excitation light source for stable luminous efficiency and long life
