Description

The basic AP-5000 Packages include an Aquaprobe AP-5000, a 3 meter cable, accessories and some RapidCal calibration solution all housed in a neat carry case for easy storage and transport. There are also packages available including an interface. The GPS Aquameter Display shows the readings from the connected AP-5000 probe.

The Aquaprobe AP-5000 includes four empty Aux sockets pre-fitted with removable blanking plugs, that can be customised with additional Aquaprobe sensors. 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.

The Aquaprobe AP-5000-PACKAGE includes the base AP-5000 Package, plus the handheld GPS Aquameter display as the main interface. This unit will connect to the AP-5000 sensor and collect the readings it provides.

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
