CMM Room Ambient Tempature & Humidity

CMM Room Ambient Tempature & Humidity

CMM Room Ambient Tempature & Humidity

(OP)
We are setting up a special room for a new CMM machine to measure fixtures and gages for automotive parts. I need to know what the range of relative humidity should be. I know ambient tempature is 68-70 degrees F, but what is range for humidity?

Also does anyone know of any inexpensive instruments for tracking the tempature and humidity that can hook to the PC?

RE: CMM Room Ambient Tempature & Humidity

ASME B89.6.2-1973, "Temperature and Humidity Environment for Dimensional Measurement" states the following with regard to humidity:

"5.1.2 Humidity. Requirements for humidity control arise from desires to provide human comfort, to prevent deleterious effects of moisture such as corrosion of workpieces and measurement apparatus, and to maintain measurement accuracy of workpieces that are dimensionally sensitive to moisture (for example, certain hygroscopic materials). Specifications for humidity control shall be consistent with the practices established by the American Society of Heating, Refrigeration and Air-conditioning Engineers."

So, they don't provide a specific numerical range for humidity in the standard ad I do not happen to have a copy of the specifications from the American Society of Heating, Refrigeration and Air-conditioning Engineers.  But, hopefully this info will be of some help to you.
