Title: Recommended relative humidity in electronic lab
Post by: Hrvoje-CRO on March 25, 2014, 03:28:55 pm
Hi!

Well this one is relatively important thematic.

What is recommended relative humidity for electronic equipment/lab/el. components?
In my lab at this moment is about 50%, during summer is about 65%, even little bit more.

Thank you!

Personally I think thats perfectly fine :-+.

the same humidity a on the calibration certificate. anything else is no-go

Maybe, but that can only be possible if using dehumidifier.

This depends largely on what the lab requirements are and what needs to be measured

I have one customer that needs highly accurate high voltage measurements and the equipment
is located in an air conditioned room.
This way, we can achieve a better than +/- 0.5 kV accuracy over a one year period of 40 kV Pk/Pk

An other client does not have any control over his room temperature or humidity.
Winter time down to 18°C and Summer time up to 35°C
Under these conditions, we can not even hold +/- 4 kV accuracy over a one year period of 40 kV Pk/Pk
So we need to calibrate the equipment once a month or when the temperature or humidity changes big time.
