Patent number: 11656180Abstract: A fluorometer is provided for monitoring the quality of water, featuring an array of excitation sources, an array of multiple emission detectors and a signal processor. In the array of excitation sources, each excitation source provides respective excitation source optical signaling at a respective illuminating wavelength. The array of multiple emission detectors detects multiple emission wavelengths emitted from water containing information about multiple coexisting fluorescent species present in the water that emit optical radiation at at least two different wavelengths when illuminated by the respective illuminating wavelength provided from the array of excitation sources, and provide multiple emission detector signaling containing information about the multiple coexisting fluorescent species.Type: GrantFiled: November 18, 2019Date of Patent: May 23, 2023Assignee: YSI, INC.Inventors: Kevin R. Flanagan, Christopher J. Palassis

Patent number: 9200929Abstract: A probe head is disclosed that is detachable from a probe body containing electronics. The probe head includes a housing enclosing a sensor and at least part of an electrical connector electrically coupled to the sensor. The housing has a coupling member positioned to detachably connect the housing to the probe body, and when the probe head and probe body are coupled, the electrical connector electrically couples the sensor to the electronics within the probe body. The probe head may be disposable.Type: GrantFiled: January 21, 2014Date of Patent: December 1, 2015Assignee: YSI INCORPORATEDInventors: Christopher J. Palassis, Michael T. James

Publication number: 20100321046Abstract: A conductivity sensor is disclosed that comprises a forked electrode support that includes a first opposing arm and a second opposing arm spaced apart by a slot. Both the first arm and the second arm include a plurality of electrodes embedded in each arm. The first and second arms and the slot are capable of retaining a volume of fluid within the volume defined by the arms and the slot such that the conductivity of the fluid in the slot can be determined. The conductivity sensor is wipeable by a reciprocating wiper assembly positioned adjacent the forked electrode support such that the wiper element can travel through the slot and remove contaminants from the slot and the plurality of electrodes in each of the first and second arms. Also disclosed are methods of making the conductivity sensor.Type: ApplicationFiled: June 14, 2010Publication date: December 23, 2010Applicant: YSI IncorporatedInventors: Robert C.
