The Broadsensor ppb class optical DO sensor is coated with a luminescent material. Blue Light from an LED strikes the luminescent chemical on the sensor. The luminescent chemical instantly becomes excited and then as the excited chemical relaxes, it emit red light. The red light is detected by a photo diode. The time it takes for the chemical to return to a relaxed state is measured by referring an independent red led light. Oxygen has a dampening effect on this reaction. The oxygen concentration is proportional to the time it takes for the luminescent material to return to a relaxed state.
The AQUA200 water platform is rugged in aquaculture water, delivering accurate, reliable data in an easy-to-use for end fisherman. Base sonde configuration includes optical dissolved oxygen(optical DO), pH, ORP, temperature and wiper system.
Online ODO sensor is widely used, so BroadSensor developed the fluorescent cap.Low drift and can be stored in the air
Broadsensor online pH/ORP Sensors with Integrated Digital Electronics for Plug and Play Capability with Broadsensor multi-parameter sonde and IP68 connector to any PLC. pH/ORP sensors have a unique design that incorporates a user-replaceable sensor tip (module) and a reusable sensor base that houses the processing electronics. This allows users to reduce the costs and easy to maintain.
Broadsensor online ISE (Ammonium) sensor with integrated digital electronics for plug and play capability with Broadsensor multi-parameter sonde platform and IP68 connector to any PLC or DTU. It has a unique design that incorporates a user-replaceable electrode tip (module) and a reusable sensor base that houses the processing electronics. This allows users to reduce the costs and easy to maintain.
The content of blue-green algae was monitored by fluorescence analysis. This method directly detects the fluorescent substances of specific pigments in the cells of blue-green algae to determine the relative blue-green algae. The sensor is IP68 waterproof and supports Modbus protocol. It can be widely used in rivers, lakes, drinking water sources and other fields.
Chromophoric Dissolved Organic Matter or Colored Dissolved Organic Matter (CDOM): Both refer to organic matter in water that absorbs strongly in the ultraviolet (UV) spectrum. Fluorescent Dissolved Organic Matter (fDOM) refers to the fraction of CDOM that fluoresces.
