Description

The Aquaprobe AP-6000 sensor is the same as the AP-5000 sensor, but includes four Aux sockets with removable blanking covers and feature a rotating arm in the centre of the probes that cleans each of the installed probes to ensure they are clear of any dirty and debris. Any ISE or Optical sensors can be fitted to any of the four empty ports. Sensors supplied with the AP-5000 cover Water Depth, pH, ORP, Conductivity, TDS, SSG, Resistivity, Salinity, Dissolved Oxygen and Temperature. All sensors are designed to be fully submerged in water and are rated to IP68, they are rated for continual immersion to a depth of 30 meters, and short term immersion (less than 12 hours) to 100 meters.

Self Cleaning System on the AP-6000

The new, smaller removable central cleaning arm of the AP-6000 consists of a rotating set of brushes that clean all of the connected sensors, including the EC sensor located on the side of the optical DO probe. The cleaning arm, that features a small motor inside, can be easily unscrewed for maintenance, brush replacement and cleaning. Wiping the sensors regularly in this way can increase the deployment duration substantially, even in demanding environments.

The main advantages of the AP-6000 are its versatility and its price point. The Aquaprobe is small enough to be used portably as part of a package including carry case, but it can also be used with an Aqualogger or with telemetry if you require a more determinant monitoring solution.

Advanced Optical DO sensor

The optical sensor works on the principle of Dynamic Luminescence Quenching. A gas-permeable material known as a luminophore is excited with short bursts of blue light, which causes molecules in the luminophore to emit red photons. By measuring the delay of the returned red photons with respect to the blue excitation, the level of dissolved oxygen present can be determined.

The optical method has various advantages over the historical galvanic method for measuring dissolved oxygen.

The most important being that as no oxygen is consumed across a membrane, the sensor does not require a flow of liquid passing over it to achieve a stable reading. Other advantages include in frequent calibrations (every 3-6 months), and replaceable caps that last over 2 years
