Q46D Oxygen Monitor: Powerful Performance for Monitoring Dissolved Oxygen Levels
Monday, July 1, 2019

Are your plants gasping for air? Are they close to suffocating?

The amount of dissolved oxygen can tell you a lot about the quality of your water. Both fish and plants need dissolved oxygen in the water so they can survive. Just like we need oxygen in the air to breathe, they too need oxygen in the water.

If you aren't quite sure of the dissolved oxygen levels in your water, then the Q46D Oxygen Monitor can benefit your company. You're going to want to check out this monitor for your dissolved oxygen levels.

What is Dissolved Oxygen?

The saturation value of the water is going to be the maximum amount of oxygen that it can hold. Usually, cold water will hold more oxygen than warm water. It is possible to exceed the water's natural saturation value.

This is usually done in a greenhouse setting and is known as super-saturation. The dissolved oxygen levels in water are measured in milligrams per liter (mg/l). They can be measured as a percentage of saturation or as parts per million (ppm).

There are a variety of different factors that can affect the dissolved oxygen levels of water. These include chemical and/or biological demands as well as the salinity of the water.

Salinity is the amount of salt in the water. Saltwater tends to have less oxygen than fresh water.

Dissolved Oxygen Levels for Plants

If you own a greenhouse and are hoping to keep your plants alive and healthy, then the dissolved oxygen in your water should be a priority. Plants are able to grow with about 5 mg/l of dissolved oxygen. Although, they will grow even better with a higher percentage.

Growing plants in water with 8 mg/l or higher can yield better results. Anything below 4 mg/l is dangerous and could cause plants to die. It is called hypoxia when the water's oxygen level is depleted to the point that it cannot support life.

Many greenhouse owners don't even know how close their water is to hypoxic levels! Which is why it is important to closely monitor the levels of dissolved oxygen.

Levels for Fish & Animals

Fish, invertebrates, bacteria, and other aquatic life need dissolved oxygen in order to survive underwater. They breathe the water just like we breathe the air!

That's why dissolved oxygen levels are so important for fish farming. The amount of dissolved oxygen in a tank can be affected by the temperature along with the number of organisms in the water.

Furthermore, because fish are cold-blooded animals, they will use even more oxygen at higher temperatures when they need to cool their bodies down. Similar to plants, a minimum of about 5 mg/l is recommended to support a large fish population.

However, on average you will find about 9 mg/l in a healthy lake or other fishing waters. The specifics of each species varies, so be sure to keep this in mind when maintaining the right dissolved oxygen levels in your tanks.

Monitor Your Dissolved Oxygen Levels

The amount of oxygen levels in water is an important part of supporting your crops and/or animals. This is why it is vital for you to monitor levels. Many factors can change the dissolved oxygen in the water. If it drops below the life-supportive level, it could be fatal.

Trust your oxygen levels with a reliable Q46D Dissolved Oxygen Monitor. This monitor offers high-quality performance. You can choose between two sensing technologies: Membraned Electrochemical and Optical (fluorescence).

Plus, because you'll be maintaining optimal airflow, you'll save money by preventing excess aeration.
