Parameter is a leading global manufacturer of environmental control rooms for a wide range of industries. Each room that Parameter designs is custom built to meet specific requirements for our clients. We have the capability to meet ICH, ASTM, TAPPI and FDA guidelines for any room or storage condition.

Parameter designs and deploys equipment and provides stability storage for customers in these industries:

Choose Parameter as your single-source provider of planning, designing, building, testing, installation and long-term maintenance and validation.


Parameter designs and manufactures rooms in our North Carolina facility to operate at the specific requirements and exact sizes you’ve specified. To ensure product integrity, Parameter assembles and thoroughly tests all systems prior to shipment and provides complete installation and on-site start-up instruction anywhere in the world.

Parameter is fully capable of upgrading any brand of existing rooms. Due to the flexibility of the Parameter conditioning systems we can also condition your existing rooms.

Rooms are built using modular insulated panels with either a 32 R-value (4″) or a 40 R-value (5″) to maximize efficiencies and uniformity. We can provide options for stainless steel construction, dryers, and air and water filters if needed.


Parameter rooms and chambers use a unique method of controlling moisture to attain unmatched levels of humidity and temperature control and uniformity. Unlike many other manufacturers, Parameter’s humidity methodology does not use vapor generators or atomizers as a humidity source. Instead, our dew point generating system achieves superior levels of humidity performance.

See an explanation of the Parameter system at Humidity Control 101.

The Parameter Smart Pad controller is a user-friendly system that provides control for the conditioning units. The Smart Pad is equipped with direct readings in both temperature and humidity, and features 60-segment programming for automatic cycling and also ramping and soaking excursions. High-low or deviation alarms are standard as well as a serial communications port. Take a closer look at the Smart Pad.


  • Custom manufactured rooms or chambers to operate at your specific requirement at the size you need. Systems can automatically cycle conditions for running profiles.
  • Complete on-site installation anywhere in the world.
  • On-site start-up instruction.
  • PC-based monitoring systems come standard with each unit. System monitors temperature, relative humidity, saturation, and mechanical outputs.
  • Calibration and PM contracts.
