Aquaread Aquaplus Portable Dissolved Oxygen Meter

 The AquaPlus handheld dissolved oxygen meter is a simple to use, accurate device which incorporates a combined optical dissolved oxygen, electrical conductivity and temperature sensor. Supplied with our Aquaplus meter the portable water quality meter can be used to collect manual readings via the devices display or record readings to the Aquaplus handheld's large internal memory.

Tech behind the AquaPlus

The Aquaread AquaPlus 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.

Auto salinity compensation

When measuring % saturation the salinity of the water has an influence on the dissolved oxygen % saturation measurement. The AquaPlus has a built in conductivity sensor meaning that the salinity is calculated, this value is then used for auto compensation giving the most accurate measurements with no extra user input.

Features

  • Advanced optical DO system : 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 bright red and blue LED’s of the optical DO sensor. 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
  • Combined DO/EC/Temp Sensor : The AquaPlus sensor houses the optical sensor module on the tip, a 4 ring stainless steel conductivity sensor and an embedded temperature sensor. The inclusion of the EC sensor allows the unit to calculate the salinity and automatically compensate the % saturation reading for salinity effects.
  • Use the GPS DO Meter : Using the AquaPlus with the GPS DO meter means that the location of every reading you record is logged with every data set.This information can be utilised in OxiLink where you can export a Google file to display your measurements on a map.
