Each and every species on our planet depends on Water and Oxygen. In the case
of aquatic species, they require an adequate amount of dissolved oxygen for

Dissolved Oxygen (DO) is the amount of oxygen dissolved in a unit of water.
Oxygen gets into water by diffusing within the surrounding air, aeration
(turbulent movement), and as a waste product from plants through
photosynthesis. Dissolved oxygen levels are directly related to good water

In other words, Dissolved oxygen refers to the level of free, non-compound
oxygen present in water or other liquids. It is one of the most important
parameters when assessing water quality because of its influence on the
organisms living within a body of water. A dissolved oxygen level that is too
high or too low can harm aquatic life and affect water quality. ​ Since
dissolved oxygen levels are directly related to good water quality, the two
are highly interdependent. Many factors can affect DO levels, and an
understanding of these levels in order to make informed decisions concerning
wastewater treatment operations, hypoxic zones, aquaculture facilities or
large-scale ecosystems is essential.

As described earlier, a dissolved oxygen level should not be too high or too low because it can cause harm to marine life. So here, varieties of questions arise in one’s mind – How to measure the amount of Dissolved Oxygen in Water? Which instrument is used to measure this Dissolved oxygen? How does it work?

Does it only measure the Dissolved oxygen level or any other parameter too? And many more… The answer to all these questions is “DiOx Sense”.

DiOx Sense​ has been pioneered by ​ “Silent Infotech Pvt. Ltd”.

DiOx Sense

DiOxSense​ is the compact dissolved oxygen sensing device providing industrial-grade accuracy real-time readings for the dissolved oxygen in the water. It can be used in the aquarium water as well as in the seawater tank used for the seafood (fish, crabs, lobsters) storage tanks.

Technology Used

The most popular method for dissolved oxygen measurements is with a
dissolved oxygen meter and sensor. Dissolved oxygen sensors are of two
types – optical and electrochemical, electrochemical sensors can be
further categorized into polarographic, pulsed polarographic and
galvanic sensors.

DiOx Sense consists of ​ Galvanic sensors.​ ​ In a galvanic dissolved oxygen
sensor, the electrodes are dissimilar metals. Metals have different
electro potentials based on their activity series (how readily they give
or accept electrons).

It requires the power supply of – ​ DC 5Volt / 1A or DC 5V / 2A.

Dissolved Oxygen measurements are available in the following differen

units :

– mg/l

–  % saturation

Temperature values are displayed in​ Degree Fahrenheit.
