How can I calculate relative humidity in helium?

  • #1

Main Question or Discussion Point

Hello,
I want to calculate the relative humidity in Helium. I only have the variables "dew point temperature", "gas temperature" and "gas pressure". So I tried with Magnus and Antoine equation. But I read that the Antoine equation is very unprecise. So do you know how to calculate the relative humidity in Helium with these variables?

Best regards

You do, we don't. Are we talking milliKelvin cryogenics or STP here ?
