Home – Innovation – Control Methods

Our unique humidity control system gives customers precise levels of RH/temperature control.

Parameter utilizes innovative control methods to provide customers with precise humidity and temperature control, energy efficiency and low cost of ownership.

Two-Temperature Method

Parameter has perfected its innovative “two-temperature” method as a standard control process. This state-of-the-art process is unique to Parameter — not available from other manufacturers — and offers our customers several benefits, including:

  • Extremely precise temperature and humidity control, as well as industry-leading chamber uniformity
  • No need for high-purity water
  • The elimination of service problems commonly associated with steam injection systems
  • Low energy costs — and low costs to own

Humidity Control 101

So how does Parameter achieve such precise humidity control?

The environment to be conditioned is controlled at a targeted dew point temperature and then reheated to a specified air temperature. Maintaining a constant dew point and air temperature produces a very constant relative humidity.
