Is there such a thing as a digital hydrometer? Can't some brilliant individual come up with a dual hydro/thermo that calculates actual gravity?

Anyone have ideas on this? I can't be the only one sick of using the glass tube.

Sure, here's a "Low Cost" version for the low price of $1695

Still sick of the hydrometer? You can also use refractometers. Mostly for OG, but there are some calculations that can be used for FG as well. I only use mine for OG though.

How about an automatic temperature correcting refractometer? It's what I and many others use. Only $30, well worth the price once you realize how fragile hydrometers are.

Oh sure, we just snap our fingers and the technology to make a digital Hygrometer for $100 appears. Yea, they are out there but they are not cheap. They go for better than a grand. It seems that the technology of the sensor is expensive.

This unit is $1695.



This little bad boy is $2200.



This jobber is $3800.

From what I can observe of the industrial versions it appears they use a tuning fork configuration. I am not sure if it is drive power to maintain output or resonant frequency shift in response to viscosity. If I could get my hands on the manual it might explain the calibration procedure which would reveal the method used for sensing viscosity changes.
