A paper was recently published by the Journal of Infection Diseases and Epidemiology that is promoting the use of ozone as a treatment for the Corona virus. Worth a read for sure.
Many viruses require reduced sulfhydryl groups for cell fu-sion and entry. Corona viruses, including SARS-CoV-2 (the cause of the condition now named coronavirus disease 2019 or COVID-19), are rich in cysteine, which residues must be intact for viral activity. Sulfhydryl groups are vulner-able to oxidation. Ozone therapy, a very inexpensive and safe modality may safely exploit this critical vulnerability in many viruses, inclusive of SARS-CoV-2
The Chemetrics I-2019 Dissolved Ozone Meter is a handheld, battery operated device with an LCD screen readout of dissolved ozone levels. The items needed for taking a test of the levels of ozone dissolved in water include: the I-2019 meter, a zeroing cylinder, a new testing ampoule, a light cover, a test cup, activator solution, and, of course, the sample of dissolved ozone.
Always remember that the steps for taking the test must be done quickly to avoid O3 breakdown before the test is completed. Ozone reverts quickly back to oxygen (O2), and if too much time passes from when you add the dissolved ozone to the test cup to when you take the reading, the reading will be lower than what the true ozone level is in your application.
These are the steps: 1. Turn on the I-2019 meter by pressing the ON/OFF button. The O3 symbol will appear on the screen. 2. Place the zeroing ampoule in the meter’s sample port. 3. Place the light shield over the zeroing ampoule. 4. Press ZERO/TEST button. The O3 symbol will flash for 8 seconds, after which the screen readout will read 0.0.0. 5. Remove the zeroing ampoule and set that aside. Keep the light shield for the next steps. 6. Fill the test cup to the 25 mL line with dissolved ozone. 7. Add 5 drops of activator solution to the test cup. 8. Place tip of new testing ampoule in sample cup and snap off tip against the bottom of the test cup. The vial is vacuum sealed and will fill instantly with the sample. 9. Dry the vial, place it in meter’s test port, and cover with the light shield. 10. Wait 1 minute for the test to develop. 11. Press ZERO/TEST button. The O3 symbol will flash for 3 seconds, and then the reading of the dissolved ozone level will appear on the meter’s screen.
The D16 PortaSens III Handheld Monitor with the Ozone Sensor part number 00-1009 can have the detecting range set by the user at any range from 0-5 ppm ozone up to 0-200 ppm ozone. The resolution is 0.1 ppm ozone at any range from 0-5 ppm up to 0-49.9 ppm ozone. The resolution of the readout on the screen is 1 ppm ozone when set at the range of 0-50 ppm up to 0-200 ppm. The standard range for this sensor is 0-20 ppm ozone, which has a resolution of 0.1 ppm.
The EcoSensors OS-6 Ozone Monitor has a safety control relay built in that is set to activate above the ozone human safety limit of 0.1 ppm. When this relay is wired to the Remote Alarm Panel (RAP-1), a loud audible alarm and flashing light will activate when ozone levels go above 0.1 ppm. This blog explains how to wire the RAP-1 to the safety control relay on the OS-6 Ozone Monitor.
Step 1: Remove the front panel on the OS-6. Step 2: Insert tip of RAP-1 free cable through one of the nipples on the bottom of the OS-6 monitor. Step 3: Locate the control relay labeled “ABOVE 0.1 PPM.” Connect the red wire to the Normally Open (N/O) terminal and the black wire to the Common (COM) terminal. Step 4: Replace the OS-6 front panel.
The OS-6 is now wired to the RAP-1. When mounted on a wall and powered on, an audible and visual alarm will now activate when the ozone levels are above the human safety limit of 0.1 ppm.
Recently ozone has gained a great deal of interest in the news. There is a role for a powerful disinfectant like ozone to play in the fight against COVID-19. Due to this, the use of ozone is finally gaining some worldwide attention.
For your reading pleasure we have compiled a few of the recent news stories. Have more? Send them to us, we’ll add to the list.
We are not endorsing any of the claims made in any of these articles. We are however celebrating the attention given to the power of ozone as a viable disinfectant. We hope this new awareness continues long after the COVID-19 crisis has subsided.

is a very effective disinfectant and is effective against all viruses
and bacteria. Ozone
operates according the principle of oxidation. Ozone (O3) is
instable and will revert to oxygen (O2) on it’s own, or when it
contacts something it can oxidize. Living cells found in bacteria
and viruses are very susceptible to oxidation. As ozone enters
cells, it oxidizes (destroys) their components including the cell
wall. Once ozone has
entered, the process destroys all essential components (enzymes,
proteins, DNA, RNA). When the cellular membrane is damaged during
this process, the cell will fall apart. This is called lysis
— the disintegration of a cell by rupture of the cell wall or
membrane. From this point there is no recovery and the pathogen is
inactivated. Due to the direct oxidation ozone causes (loosing the
oxygen atom) there is greater energy to ozone oxidation vs other
commonly ozone is used dissolved into water. When dissolved in water
ozone increases the ORP (oxidation reduction potential) of the water,
all of the water is now a sanitizer with electrical potential for
pathogen inactivation through lysis. When the water (with sufficient
ozone levels) contacts a pathogen it will react with that pathogen
inactivity it. This is extremely efficient and effective.
can also be used in the ambient air in the gaseous form for
antimicrobial applications. Ozone in air is a spacial
consideration. The air is not charged as water is when ozone is
dissolved in water. Air simply has ozone in within it.
example. 0.1 ppm ozone is the safe limit for humans in air for
an 8 hour period of time. 20.0 ppm is a relatively high level
used in rooms at times for disinfection. This means 20 parts of
every 1 million parts of the air are ozone. This ozone
molecule needs to react with a pathogen cell to inactivate it. The
likely-hood of this in a short period of time is low.
ozone reverts back to oxygen quickly and frequently, longer
the exposure times
increase the odds of ozone reacting with the pathogen. Ozone
reverts back to oxygen faster (shorter half-life) as temperatures and
humidity increase. Therefore, higher
ozone levels, higher
temperatures, and higher humidity will
the opportunity for ozone to react with pathogens on surfaces.
Ozone levels used
for sanitation should be chosen based upon the goals and requirements
for this space, and the ambient conditions present. Reasonable
levels of 5-10 ppm are commonly used. Higher levels are also
possible. Keep in mind any natural rubber materials will be damaged
by ozone use at high levels over long periods of time. Therefore,
keep ozone levels and frequency of use reasonable.

are great resources to use to ensure ozone is the right solution for
your application. Should you need more specific information let us
know, we will provide what we have.
A few options we
have for ozone sanitation in rooms are listed below. These systems
can also all be used in an HVAC system to maintain low levels of
ozone in a building for room air disinfection.
The S-200 ozone monitor will measure ozone as a handheld or with an optional remote sensor. Min/Max/Average ozone levels displayed on the screen along with current ozone levels.

For higher ozone levels with greater accuracy the UV-106L ozone analyzer can be used to measure and control ozone levels. The UV-106L includes built-in data-logging and accuracy to within 2% of reading. With a faster warm-up period, and greater accuracy the UV-106L is a great option for portable systems or systems that require greater accuracy.
Ozone levels in the room can be quickly converted safely back to oxygen via an ambient ozone destruct unit. The CDA-250 is a great device for this purpose. It flows 250 CFM air through the unit and destroys at least 90% of the ozone via a catalytic material in each pass. Using this device will lower ozone levels to a safe level quickly for faster turn-around time for your ozone disinfection room or chamber.
Gas gas can be an effective disinfectant in the gaseous form, but must be used safely and with proper caution. Should you have questions on this application, or any details, please contact our office.

1. Make certain all people, pets, and plants are out of area. Close all windows and doors.
2. Place the Ambient Ozone Generator on a shelf or tabletop as high as possible in the area to be treated.
3. Plug the power cord into a grounded, 3-prong outlet.
4. Set the timer to the desired length of time. Momentarily pressing the UP timer button for one second will increase the time setting by one minute at a time. Hold the button for 1 -3 seconds to change the time value by two minutes per second. Hold the button for longer than 3 seconds and the time setting will change in 20 minutes increments. The maximum time setting is 29:59 hours. After reaching the maximum time, the timer will wrap back to 00:00 and then continue increasing. When the time is being decreased and reaches 00:00, it will wrap to 29:59 and continue decreasing.
5. Select the desired power level: 25%; 50%; 75% 100%. The Ambient Ozone Generator always defaults to 100% when you plug it in. When the output level is set to 100%, the machine makes ozone continuously until the timer runs out or the OFF button is pressed. At other power level settings, the machine will produce ozone for the fraction of a minute the level is set at. For
example, if the output level is set to 75%, the machine will produce
ozone for 75% (45 seconds) of each minute. At 50%, ozone is generated
for 30 seconds of each minute, and at 25%, the ozone generation lasts
for 15 seconds of each minute. On any setting other than 100%, the ozone generator will be cycling the ozone ON and OFF.
6. Turn the unit on by pressing the ON button. Leave the area immediately.
7. When treatment is complete, ventilate the area completely until
all smell of ozone is gone. Do NOT allow people, pets, or plants back
into the area until all smell of ozone has dissipated.
