Optical Electrodes

The Aquaread range of interchangeable optical probes comprises advanced, solid-state sensors engineered for high-precision environmental water quality profiling. Operating on advanced optoelectronic principles such as dynamic luminescence quenching and sapphire-lensed fluorometry, these probes plug directly into auxiliary sockets on AP-Lite, AP-2000, AP-5000, AP-6000 and AP-7000 Aquaprobes. They are designed to deliver drift-free, real-time measurements in fresh, brackish, or marine waters without requiring sample flow.

Unlike traditional electrochemical sensors, Aquaread’s optical probes utilise highly stable optical excitation and emission paths, minimising calibration drift and eliminating consumable membranes or electrolytes.

Key Features

  • Interchangeable Plug-and-Play Design: Standardised physical dimensions allow users to easily swap between different optical parameters in any open auxiliary optical socket.
  • Dynamic Luminescence Quenching: The Optical Dissolved Oxygen (DO) probe measures the phase shift of returned red photons to calculate DO without consuming oxygen, ensuring high accuracy in stagnant water.
  • Sapphire-Lensed Optics: Turbidity and fluorometer sensors utilise scratch-resistant sapphire lenses to optimise light transmission and withstand aggressive field deployment.
  • No Consumables or Membranes: Eliminates the need for electrolyte solutions or delicate membrane replacements, significantly reducing long-term maintenance overhead.
  • Wide Parameter Selection: Probes are available for Turbidity, Chlorophyll, Blue-Green Algae (Phycocyanin/Phycoerythrin), Rhodamine, Fluorescein, Refined Oil, and CDOM/FDOM.

Images for each show each parameter as it was added to clear fresh water to provide a clear indication of the appearance change for each.
