Parameter is a leading global provider of environmental control rooms and chambers for the packaging, pulp and paper industries. Parameter specializes in humidity control and conditioning systems, adhering to TAPPI standards for product storage and box testing.

Parameter Generation and Control (PGC) manufactures TAPPI reach-in chambers, room systems and conditioners for existing laboratories. Parameter’s precise temperature and humidity control of ±0.2° and ±0.5% help insure that you meet the stringent TAPPI T402 sp-08 specification. In small modular rooms and reach-in chambers, the Parameter system can run the TAPPI preconditioning atmosphere and then automatically ramp to the conditioning/testing atmosphere.

Our Advantage

Parameter’s precise control and distribution for stability chambers allows for problem-free mapping validations. Equipment is reliable, cost effective, and has low energy requirements.

Parameter Precisely Controls:

  • Control constancy – Parameter provides precise single point humidity and temperature control
    (±0.5% RH / ±0.2°C).
  • Uniformity across the conditioned space – Parameter provides a tight uniformity by engineering optimal distribution systems that evenly disperse the air through a conditioned area.
  • Sensor Accuracy – Parameter utilizes high grade humidity and temperature sensors and maintains the calibration over the range of conditions required.
