We chose 10 - 90% as our range after reading what few instrument manuals even addressed the issue. I can only wish we could get to 17% humidity here in NC.

The Inspecting Organization will want me to cite a range for HUMIDITY in the lab. Because this not only hinges on our weather (we're in Monsoon Season right now and the lab humidity is 47% as I write but is normally between 17-20%), but also MUST be based on any of the histology equipment that may be affected by humidity in any way. Realizing that we all work in different "environments" and usually have little or no control over the HVAC system, what did you decide upon as your HUMIDITY RANGE for the SOP under which you operate? If there are no specific equipment requirements, I will be able to give a range of 0-100% without the necessity for a Corrective Action Report. If I am too specific and give too narrow a range, I may end up filling out a Corrective Action Report for days when I'm "out of range". Please give me as much detail as you are able, without being required to join me in hiding. Your input will be rewarded (don't ask).
