AQUAPROBE AP-5000 supplied with Optical DO, EC, pH, ORP, Temperature and Depth sensors.
£2,950.00
The AP-5000 sensor comes with the Aquaprobe AP-5000 with Optical DO, EC (& Calculated parameters), pH, ORP, Temperature and Depth sensors. The AP-5000 has four empty Aux sockets pre-fitted with removable blanking plugs, that can be fitted with any ISE or optical sensor. The 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 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
