-49,5 °C at 226 kPa (2.26 bar). So when measuring humidity in terms of frost/dew point in the typical SF 6 range (-3…-60 °C) using a chilled mirror hygrometer, there is clearly a risk that an optically detected condensate layer could be SF 6. From a humidity perspective this adds a potentially significant measurement uncertainty,Get price
