Aquaprobe optical water quality sensors for the AP-6000 & AP-7000 digital water quality sensor. These advanced optical electrodes are incredibly practical, allowing for easy, tool-free removal and replacement in the field. They’re designed specifically for seamless integration with the AP-6000 and AP-7000 sensors, to provide a additional parameters to your water quality monitor sensor. The AP-7000 Optical Electrodes offer measurements of Turbidity, Chlorophyll A, Blue Green Algae (fresh and salt water options), Rhodamine, Fluoresceine, CDOM/FDOM and refined oil.
The AP-6000 & AP-7000 water quality probes are multi-parameter sensor and comes pre-fitted with probes covering pH, ORP, Conductivity, TDS, SSG, Resistivity, Salinity, Dissolved Oxygen, Temperature and Depth Sensor. Each AP-6000 probe comes with four empty sockets, and the AP-7000 has six empty sockets. These allow for the addition of Optical, or Ion Selective Electrode (ISE) sensors. This page covers the 8 Optical Electrodes that can be fitted to any of these Aux Ports on the AquaProbes. Additional parameters covered by the Optical Electrodes are: Turbidity; Chlorophyll; Blue Green Algae; Rhodamine; Fluorescein; Refined Oil; or CDOM/FDOM.
The table below covers the available parameters, with links to get more details on the parameter for each probe.

Fluorescence measurement techniques are not ideal for quantitative measurement and it is therefore impossible to specify an absolute accuracy. The accuracy figures quoted above represent the equipment’s capability at the calibration points at 25°C. In order to obtain accurate results, data obtained with a fluorescent electrode in the field must be post-calibrated with data from standard laboratory analysis of grab samples acquired during the study.
Both the AP-6000 and AP-7000 AquaProbes include automatic cleaning mechanisms which are incredibly beneficial for any optical sensor. The brush and wipers are critical because they:
