BUILT FOR PRECISION. TRUSTED FOR CONTROL.
At Parameter Generation & Control, we design and build environmental chambers for industries where conditions must be precise. From high-performance stability rooms and reach-in chambers to ultra-dry storage and tightly regulated cold environments, we bring a level of control and consistency that supports critical science, product testing, and compliance.
For nearly five decades, clients have relied on us for projects with demanding specifications, tight tolerances, and challenges that go beyond standard equipment. That’s where our expertise makes the difference.
What sets us apart is our proprietary Two Temperature Method—a control strategy unique to Parameter systems. By independently regulating both heating and cooling functions, we deliver exceptionally stable environments with minimal deviation. It’s this method that allows our chambers to maintain tight tolerances, even under load, over time, and across changing & challenging conditions.
Every chamber we build reflects decades of applied engineering, a deep understanding of regulatory requirements, and a relentless focus on precision.
If your project requires control beyond the ordinary, you’re exactly who Parameter Generation & Control builds for.
