Parameter manufactures custom walk-in rooms for the packaging, pulp and paper industries that comply with ICH, ASTM and TAPPI standards. Each room is built to your exact specifications and our systems provide the precise temperature and humidity control required by both TAPPI T402 om-88 and preconditioning specification, TAPPI T 402. The system can automatically cycle between the two conditions.

Common conditions for our rooms are:

  • 23° C / 50% (Main TAPPI Spec.)
  • 35° C / 30% (TAPPI pre-conditioning)
  • 32° C / 90%
  • 5° C / 85%

TAPPI Tolerance is ±0.5°C and ±2% RH
