AWT is almost here, and for Pyxis Lab, this is one of our favorite weeks of the year.
The 2026 AWT Annual Convention & Exposition takes place September 16–19 in Oklahoma City, bringing together water treatment professionals from across the industry for education, networking, and a look at the latest technologies shaping the future of water treatment. You can find the Pyxis Lab team at Booth #209 throughout the show.
This year, we are bringing more than familiar faces. We are preparing to unveil new technology, showcase major upgrades, and give attendees a closer look at several platforms designed to provide more insight while reducing the maintenance and complexity of traditional water analysis.

Whether you have worked with Pyxis for years or are seeing our technology for the first time, stop by Booth #209 to meet the team, get hands-on with our latest equipment, and talk through the applications and challenges you are seeing in the field.
Unveiling the OXIPANEL Generation 2
One of the biggest highlights at this year’s show will be the official unveiling of the Generation 2 OXIPANEL.
Built around the same goal that has always driven the OXIPANEL Series – reliable, real-time oxidizer monitoring with less maintenance – Generation 2 introduces several major upgrades designed to improve control, sensor performance, cleanliness, and usability.
The new platform combines the upgraded UC-80 PLUS color touchscreen and data logging terminal with expanded inputs and outputs, advanced ST-766SS sensor technology featuring simplified electrode head replacement and integrated conductivity measurement, and the new FR-306 PLUS self-brushing flow reservoir. Together, these upgrades help maintain stable measurement conditions, reduce sensor fouling, simplify operation, and extend maintenance intervals in demanding applications.
The Generation 2 OXIPANEL is designed to measure your selected oxidizer alongside pH, ORP, Conductivity, and temperature, while automated temperature and pH compensation help support consistent oxidizer measurement.
The upgraded FR-306 PLUS adds to the automated mechanical brushing accessory. The motorized brush helps keep the sensor measurement surface cleaner in challenging water conditions, reducing the need for frequent manual intervention.
Smarter Flow. Cleaner Sensors. Better Control.
AWT attendees will be among the first to get an up-close look at the new system and speak directly with the Pyxis team about what has changed.
Introducing the ST-500X: A PTSA Sensor That Provides a Sensor Cleanliness Value
We are also bringing the new ST-500X Series to AWT.
Traditional PTSA sensors tell you the concentration they are measuring without compensation. The ST-500X goes a step further by providing insight into the condition of the sensor itself while still automatically compensating for color and turbidity.
The ST-500X continuously measures PTSA from 0–500ppb while using a dedicated second 4-20mA output to provide a 0–100% sensor cleanliness value.
That cleanliness value can be sent directly to a controller, PLC, DCS, or other monitoring platform, turning the sensor cleanliness into a continuously available process variable rather than an occasional manual diagnostic.
For operators, that means the ability to:
- Identify developing optical fouling before it impacts measurement reliability
- Establish maintenance or cleanliness alarms
- Schedule cleaning based on actual sensor condition instead of arbitrary intervals
- Gain greater confidence in the PTSA measurement being used for chemical control
The ST-500X also incorporates automatic compensation for sample color and turbidity, giving operators another layer of intelligence in applications where changing water conditions can influence optical measurement.
It is no longer just:
“What is my PTSA?”
It is also:
“Can I trust the condition of the sensor measuring it?”
See the ST-500X first at AWT Booth #209.
See the Titronex™ MFA-Series in Action
AWT attendees will also have the opportunity to get a closer look at the Titronex™ MFA-Series, the Pyxis Lab approach to simplifying automated wet-chemistry analysis.
Rather than relying on traditional metering pumps, the Titronex™ platform uses sealed reagent cartridges and a gravity-assisted tube-roller dispensing mechanism to introduce precise reagent volumes into the reaction chamber. The system automates sample handling, reagent delivery, reaction, measurement, and discharge within one analyzer platform.
The Titronex™ MFA-Series supports multiple analytical methods and chemistries, including:
- MFA-600 Calcium Hardness
- MFA-100 Free Chlorine
- MFA-110 Total Chlorine
- MFA-310 Orthophosphate
- MFA-400 Anionic Polymer
Depending on the chemistry, individual reagent cartridges can support thousands of automated measurements, within capacities ranging up to 16,000 tests on select models.
The goal is simple: take the precision of wet chemistry and make online analysis easier to operate and maintain.
Wet Chemistry. Without the Drama.
If you have been curious about the Titronex™, AWT is the perfect opportunity to see the platform up close and talk with the team behind it.
More Than New Products
Of course, the Pyxis booth will feature much more than these three highlights.
Our team will be on hand to discuss the broader Pyxis portfolio of inline sensors, handheld instrumentation, controller and connectivity solutions, and complete analyzer platforms for industrial water treatment.
But more than anything, AWT gives us an opportunity to spend time with the people who use this technology every day.
Bring us the difficult applications. Bring us the water that keeps fouling sensors. Bring us the measurement problems you have been trying to solve. Those conversations are often where our next ideas begin.
A New Chapter for Pyxis Lab
The year’s AWT also comes at an especially exciting time for Pyxis.
Following our recent announcement that Pyxis Lab has joined Halma, we’re entering a new chapter with additional resources, expertise, and global reach behind us while continuing the innovation, customer relationships, and water treatment focus that have shaped Pyxis from the beginning.
For us, AWT 2026 is an opportunity not only to showcase what’s new, but to celebrate what comes next alongside many of the customers, distributors, partners, and friends who helped us get here.
See You in Oklahoma City
AWT has always been one of the highlights of our year, and 2026 is shaping up to be a special one.
Come see the Generation 2 OXIPANEL for the first time. Take a closer look at the new ST-500X and its continuous sensor cleanliness monitoring. Explore the Titronex™ MFA-Series. Meet the Pyxis team, ask questions, and see what we have been working on.
