Exactly... As soon as the probe was placed in the steam flow, some condensation would occur on it, but within seconds the probe would heat up and the condensation will evaporate. -Mark -----Original Message----- From: Michele Comitini [mailto:michele.comit...@gmail.com] Sent: Wednesday, June 22, 2011 1:19 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:relative humidity 2011/6/22 Abd ul-Rahman Lomax <a...@lomaxdesign.com>: > The problem with this is that water would condense on the probe.

So we should think Galantini setup instruments picking up the first probe without understanding how it works.
