There are three primary technologies used to monitor and measure ozone: Electrochemical cells, HMOS / GSS, and UV. Today we will be giving a brief overview of HMOS / GSS sensors and their use.
HMOS (Heated Metal-Oxide Semiconductor) and GSS (Gas-Sensitive Semiconductor) based ozone sensors function by heating a small semiconductor substrate to high temperatures, causing it to be extremely sensitive to ozone. This is seen as a change in the resistance of the material, which is measured by the circuitry, interpreted as ozone, and either displayed or output for our use.
One of the key benefits of this sensor technology is that it is very inexpensive, allowing widespread adoption at many facilities. It is commonly used for both portables and wall-mount ozone monitors.
Another advantage to semiconductor-based sensors is their solid ozone response below 0.1 ppm. This allows them to be used in many ambient ozone safety scenarios, with a display resolution as fine-grained as 1 ppb. While not as stable or sensitive as UV-based ozone analyzers in this range, they are worth consideration for ambient safety scenarios where low ozone concentrations are expected.
Disadvantages include a short battery life (due to the continuous heating of the sensor) and the extended warm-up time that the sensor requires.
Common Applications:
Ambient ozone safety monitoring
Leak Detection
Ozone control scenarios, especially at levels below 0.1 ppm
Here are a few monitors offered by Ozone Solutions that utilize HMOS Sensor technology:
As per federal law and state law, any organization or company who generates ozone gas must have ozone MSDS (material safety data sheets) readily available.
These new MSD sheets also contain the newly mandated OSHA 16 section format with specific required information.

The Hull Chamber of Commerce Awards Night was held on Saturday, March 17,2012. During this award night Ozone Solutions was awarded the 2011 Employer of the Year.
Nominations are submitted by community members who are appreciative of businesses commitment to the community. It was noted during the award ceremony that Ozone Solutions has a number of employees who are on both the ambulance and fire department. Ozone Solutions is willing to have their employees take call during the day to respond to emergencies in the community, and because of this commitment, the Hull Chamber thought Ozone Solutions was worthy to receive the award.
Pictured below are a few of the employees who were present to accept the award:
Pork Processor share in a very competitive market, driven by food safety, quality, and demand planning and price point. In addition pork processors are challenged with developing and adhering to strict FDA, USDA and State regulations.
QA management teams strive for excellence, identifying new technologies to enhance existing HACCP & Safe Food Practices. Ozone is the new antimicrobial intervention step. Ozone has been in a constant state of development for the past decade, advances in science and improved technology has brought Ozone to the forefront of pork processing technology. {Please see the HACCP example below} or click here to access >> Pork HACCP Applications
The applications are abundant, beginning with the receiving/holding phase thru the full body & Evisceration cavity antimicrobial wash to the “Chilling – Ozone Misting” to “Storage – Ambient Air/gas systems”, all the way to the processed packaged retail cuts, extending the supply chain shelf life cycle.
Applied ozone as an antimicrobial intervention works replacing or eliminating chemicals reducing operational cost. Ozonated recycled denatured water is also used “for example” in CIP as a receiving and holding washout stage a value added HACCP step.
Ozone is an excellent application to improve your HACCP & Food safety Plan.
A University of Alberta research team has discovered that technology commonly used to decontaminate food industry equipment can also rid meat processing plants of lethal microbial material (Bovine Spongiform Encephalopathy) responsible for the human version of the ailment Mad Cow disease.
U of A microbiology professors Mike Belosevic and Norm Neumann and engineering professor Mohamed Gamal El-Din demonstrated that infectious proteins found in the brain matter of cattle can be eradicated from water treated with ozone.
Strickland Produce of Nashville, TN successfully implemented ozone into their vegetable processing facility. Ozone, a powerful micro-biocide, destroyed natural pathogens found on lettuce and fresh greens. Ozone was integrated into flume water and resulted in significant savings. The savings resulted from reduced chlorine usage and reduced labor costs associated with changing the flume water.
Lettuce & Carrots after Ozone Treatment
Using a microbiocide, such as ozone, is important for the treatment of lettuce because lettuce can be consumed raw. Therefore, if proper pathogen treatment is omitted, or improperly implemented, during the processing steps, there is the chance that humans will come into contact with pathogens such as e-coli O157:H7. Using ozone can significantly reduce this risk.
Below is a paper on the successful implementation of ozone at Strickland Produce.
Additional Ozone Benefits
60% water savings on 2 treatment lines
reduced cooling water costs
reduced labor associated with water change-out
Strickland Produce estimated the ozone treatment system had a 21 month payback not including lower refrigeration costs, lower wastewater discharge costs and increased production.
OZONE WORKED FOR STRICKLAND PRODUCE AND IT CAN WORK FOR YOU TOO!
Today’s meat packing and processing industry is continuously evolving, seeking new innovative solutions that reduce cost, improve quality and extends the supply chain shelf life cycle. While the Plant Management and Quality Assurance professionals have an increasing responsibility of improving production levels, they also have the delicate balancing act of complying with USDA and FDA regulations. Meat packing “Beef” Industry leaders have found a cost effective method to improve their HACCP “Hazards Analysis Critical Control Points”Plan. The implementation of OZONE!
The HACCP application of Ozone begins with the Pre-mortem receiving/holding “See the illustration below” progressing to the post mortem phase, antimicrobial wash of Carcass – aging – storage to the Primal & Sub-primal cuts then retail prepackaged cuts. Trimmings are also treated with antimicrobial Ozone wash just before the ground beef grinding process. Click here to see >> (Beef Processing Applications) or read below
Ozone HACCP applications encompass a complete implementations plan from the initial Antimicrobial wash, to the chilled water misting and ambient air “cooler” aging process, to packaged ready to ship products, transportation systems and CIP – Clean In Place applications.
Ozone, simply put, works with a 99.99% log 4 pathogen destruction rate with a host of applications and 100% sustainable, ozone is the right choice.

Food and fun… now it doesn’t get better than that! While working together is great, every now and then it’s fun to get together and enjoy time together outside of work.
On July 27, 2011 many of the employees of Ozone Solutions, along with their families got together for a picnic at the Hubbling Park in Hull, Iowa. Dexter (see photo) & Joel were in charge of the grilling and did a fabulous job on the steak, chicken, and hotdogs!
We also enjoyed a variety of salads and desserts brought by each of the families. YUM!!
Mike is turning the BIG 40 in a couple weeks, so we surprised him with a cake and some black decorations!
A friendly game of volleyball is now a tradition at the summer company picnic. Are we competitive? Just a little…
Many of the kids enjoyed learning how to play volleyball or spending time playing around in the sand and playground equipment.
