Just checking to see if there would be an interest in a Digital Hydrometer
and if so -- what feature(s) would you like to see and what price range would be resonable.

Here's what I am thinking:

-- Digital Display (LCD)
-- Initial design would be for 6.5 Gallon Plastic Container for monitoring primary fermentation
-- Battery Powered
-- Press button to display S.G. or continually display current S.G.
-- Improve basic design as a datalogger also to keep S.G. record of batch and be able to download data to computer for data storage or printout.
-- Also could add a temperature sensor to display ambient temperature of fermentation area.

Advantage of Digital Hydrometer:
-- No beer waste -- since sampling would not be necessary.
-- Accurate S.G. profile of batch either by data storage or manual log sheet
-- Easier to determine when fermentation is complete.

I'd really appreciate any feedback anyone would have on this --

Thanks,

Rick

I'll bite...

Would it have a built in thermometer and scale to provide a true gravity...thinking lagers, and pre-boil measurments.

How much?

Yep -- that would be fairly easy to calculate a true gravity.

I have no idea of the cost -- just a concept at this point.

It could be less that $50 -- depending on the features or as much as $100 -- but, I'm just guessing right now.

Would it be remote display and left in the ferment until it registers the FG? It has potential. It could have high/low temp alarm. Perhaps a USB port to download data to a memory stick.

Prefer Audible or Visual Alarm or both??

Yep -- that would work. A USB Port for configuring Alarms -- etc.. and a Memory Stick connected to the USB port during fermentation for data logging.

I think the alarm should be selectable. Have a blinking LED or something or an alarm should you want it to pitch yeast or something.
You could even set the FG range and once it hits it then a light blinks.

Sounds promising...

I'm betting a couple different optionable units would be best. Some people Im sure would want a bare bones unit.

Are you looking for enough interest before you start producing these, or do you have anything made already?

Just curious..whats your background and do you have any proof of concept/prototype?

I would probably be down for one. Just a simple one that would display true SG and temp and record that info to a usb would be enough for me.

That sounds great! I'd be down for one as well! Would it be able to integrate with a PC?
