AquaPlus Package

Quick Overview

The AquaPlus probe is a combined optical dissolved oxygen, electrical conductivity and temperature sensor. Thanks to the built in conductivity sensor, the AquaPlus is able to calculate and automatically compensate DO readings for changes in water salinity. It’s compact, robust and highly accurate. It also requires very little maintenance to keep it that way. The slim probe is used with its very own GPS DO meter, meaning the location of every datapoint you measure is also recorded.

Traditionally, DO measurement in portable field equipment has been done using membrane covered detectors known as Clark Cells. This type of cell suffers from problems including membrane fouling, calibration instability and worst of all, oxygen consumption. During measurement, a Clark Cell will consume oxygen making it necessary to have a constant flow of water over the cell.

Optical technology eliminates all these problems allowing high precision, membrane-free, long-term stability along with infrequent calibration and immunity to fouling by sulphides and other gases.

The Aquaread AquaPlus is the only Optical DO system that measures salinity directly. This allows for automatic salinity compensation giving you the highest accuracy in any type of water.

The Aquaread AquaPlus works on the principle of Dynamic Luminescence Quenching. A gas-permea-ble material known as a luminophore is excited with short bursts of blue light, which causes mole-cules 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.

AquaPlus with the sleeve removed reveals the combined dissolved oxygen, conductivity & temperature sensors. The end cap is replaceable however you can expect more than 2 years life from one cap
