Testo 560, apparently fault
In pdf you will find pressure/temperature scale of water and besides of this table, 3 pictures of the Testo560, 2 in Pa and 1 in Microns.
You will see that the figures on the screen of the Testo 560 doesn't match with those in the Coolpack table.
How it comes? I can't find what's wrong.Last edited by Peter_1; 21-02-2010 at 12:57 PM.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

I think you are confusing the vapour pressure with the saturated evaporating pressure.
The triple point of water is 0°C, so vapor equlibrium only exists above 0°C.

The Testo is in vacuum mode and you can see in the right corner H2O

Resolution of instrument is 80microns and accuracy is +/-0.5% of scale. I don't think it can do any better than that. Try zeroing the instrument.

Coolpack can't be wrong. It's a mathematical software. I cross confirmed the output values with another software.

NoNickname, Gerrit has a point I think, even with the given inaccuracy, the conversion between pressure and temperature must match anyhow because the Testo measures pressure and then converts it via the software to a temperature.

Re: Testo 560, apparently fault
I bet it has to do with the sea level adjustment in the testo. Its adjustable to where you reside.

Re: Testo 560, apparently fault
It starts from zero and the adjustment was done. Still not solved.
