Single Analyte Ozone Monitor
We now offer an alternative for calibrating larger dissolved monitors or to test dissolved ozone levels in a lab setting. The SAM-2 and the SAM-3 monitors are inexpensive dissolved ozone monitors that are both compact and reliable.
The SAM-2 has a range of 0.15-0.75 PPM, making it perfect for lab settings. No activator solution is required, which helps to cut costs. This monitor reads the ampoule that needs to be tested, and then will read a blank reference ampoule that is provided. If your ozone levels exceed its range, that is okay. Just dilute a fresh sample and retry the test! When you multiply the reading by the dilution factor you will have an accurate result. It is that simple.
The SAM-3 has a range of 0.20-3.00 PPM which makes it more appropriate for calibrating dissolved ozone monitors that are constantly in use (for example, an AS-500 on an ozone injection system). Using this analyte meter to calibrate your monitor monthly will help ensure accurate readings. This unit is also very simple to use – just zero it using the provided blank ampoule, and it is ready to test. This only needs to be done once (not between every test), which will speed up the testing process. After the unit is zeroed, you can test any number of ampoules.
You can get more information on these monitors by visiting the SAM-2 or SAM-3 on our website.

North Dakota State University Researches Ozone for Small Grains
The Department of Agricultural and Biosystems Engineering at North Dakota State University has been doing some interesting research evaluating ozone as a possible antimycotoxin and microbiocide for small grains. Since grains contain a variety of micro-flora (bacteria, mold, etc), processors are careful to monitor micro-flora levels and take measures to reduce them before processing. Ozone is a simple alternative for reducing micro-flora that leaves behind no chemical byproducts to pollute the grain.
UND researchers have been evaluating ozonated water (ozone dissolved in water) for reducing micro-flora, and have results indicating that ozonated water could become a common cleaning agent in the grain industry as it has in the fruit and vegetable industries.

Ozone in Water
Why dissolve ozone in water?
We are commonly asked about the uses of ozone. I want to help cover some of the basics of using ozone in water.
Ozone gas is dissolved into water for various reasons, these are just a few of the common applications of ozonated water. Click on any of the live links for more information.
- Bottled water
- Food Processing
- Surface sanitation
- Bacteria reduction
- Groundwater remediation
- Aquaculture/life support in aquariums
- Cooling towers
- Color removal
- Laundry
- Algae control in ponds
- Horticulture
- Swimming pools and spas
- Municipal water
- Iron & Manganese removal
How to dissolve ozone into water?
Ozone gas is dissolved into water just as many other molecules can be dissolved into water. This may be for a variety of reasons. There are many methods of dissolving ozone into water, however, the following 3 are most common.
Bubble diffuser
The bubble diffuser is the oldest and most common method of dissolving ozone into water. Using a bubble diffuser is also the lowest cost injection method of dissolving ozone into water. However, this is generally the least efficient method of dissolving ozone into water. In many bubble diffuser applications much of the ozone is locked up in gas bubbles that rise to the surface of the water and escape completely.
Ozone Venturi
The ozone venturi, or injector as it is commonly refereed to is a very efficient and most widely used modern method of dissolving ozone into water. By using a pressure differential across a small orifice a vacuum is created on an inlet port. This inlet port can mix ozone with the water in a violent and very efficient method.

Static Mixer
A static mixer can mix ozone with the water after it has been forced into the water stream by a direct injection port. This can be accomplished by increasing the ozone pressure to a higher pressure than the water pressure to force the ozone gas into the water stream. This is not a commonly used method, but does have some application. Static mixers can also be used after the Mazzei injector.

How to measure ozone in water?
Ozone can be measured in water using a variety of methods. The following three are the most common.
Indigo
The most common and reliable is the indigo colorimetric kit that can be evaluated by visual or photometer methods. Common test kits can be purchased for this purpose. Below is an example:
Electrochemical Sensor
The second is the inline method using electrochemical sensor cell with electrolyte solution. These sensors will use a sensor cell that is placed directly into your water flow, or a diverted water flow and give a real time dissolved ozone reading.
Indirect Measurement
The indirect measurement of ozone is not widely used or understood. This method measure the level of ozone that has off gassed from the water and provides a calculated reading based upon Henry’s law. These sensors may take a sample, or be an inline real-time sensor.
