n Features
u Up to 7 sensors could be connected to improve integration and reduce operation and maintenance costs.
u Universal, all digital sensor interfaces are common, analog sensors can be configured according to different sensor types
u Quick plug and work, electrode installation and replacement is quick and convenient.
u Easy use and reliable results, interface operation instructions can reduce operational errors.
u With 4~20mA, MODBUS RS485 multiple data output modes.
u pH, ORP, conductivity sensor easy cleaning, and the balance speed is fast, with good repeatability and stability.
u SS: Dissolved oxygen sensor adopts breakthrough fluorimetry technology, basically no maintenance, and comes with NTC temperature compensation function
u High-precision turbidity adopts 90° light scattering method, flow-through measurement, data is stable and reproducible;
u The turbidity, suspended solids/sludge concentration sensor uses the ISO7027 standard method (infrared light scattering technology) to eliminate the influence of sample color and optional cleaning brush function
u The chlorophyll sensor and the blue-green algae sensor are based on the fluorescence measurement target parameters of the pigment, which can be identified before potential blooms are affected, no need extraction or other treatment, rapidly detection to avoid the effects of leaving the water sample.
u UVCOD sensor uses 254nm spectral absorption coefficient SAC254 to reflect the content of soluble organic matter in water, and converts to COD value under certain conditions without reagent.
u Ammonia nitrogen sensor consists of an ammonium ion selective electrode, potassium ion (optional), pH electrode and temperature electrode to form an integrated sensor. These parameters can be mutually corrected and compensated for the measurement of ammonia nitrogen
n Applications
u Online monitoring of multi-parameter water quality in surface water, drinking water sources and aquaculture; Online monitoring of water quality in wastewater treatment plants and industrial sectors;
u Marine sea water quality online monitoring.
