No. The meter reads in grams per cubic meter. But the question stands
how do you get steam quality from that? steam quality is grams of
vaporized water per gram of liquid and vapor.
I think there is more than one way of expressing it. But the point
would be that the meter is not designed to give us information about
liquid water, it is measuring water vapor. Dip it in water, the
water, as vapor, will penetrate the measurement capacitor, it will
think "100% RH." Unless that capacitor can carry more water than air
can.... which seems unlikely to me! ... in which case it might show
something higher. Calibration? Specifications?
missing.
It looks like the meter was very much not designed for measuring
steam quality. That application is completely missing from the
promotional literature.
