Default How Common is a broken [miscalibrated] Hydrometer

Yeah i just posted a thread the other day about a very low Og when using extract that to my knowledge couldnt be correct. So we came to the conclusion that it must be to high of a temperature when taking the reading. So im transfering my brew from the primary to the secondary and i figure i can at least see if the fermentaion was done or almost there. However it occured to me to test my hydrometer in cooled water 70F or so and low and behold it sank so low it didnt even register on the scale. So i guess it is not calibrated? Do you guys hear of this often?

Thanks

If you've ever had a hydrometer...you've either already broken one...or you are about to break one.

Simple as that.

As far as inaccurate....the water should read 1.000 at 60F. It should sink in pure water.

How low did it go exactly? Most hydrometers are calibrated to 60 F which means that in distilled water at 70 F it is possible that the hydrometer may appear to sit slightly below 1.000

I have also noticed that in very light beers or water, hydrometers easily stick to the sides of the measurement vial...

You could always use some distilled water at your calibration temp to see what the offset is and just take that into consideration... or return the hydrometer to where you bought it for a swap.

BTW - when you say "in cooled water 70F or so" you need to be exact... every 10 degrees will throw off the reading by about 0.001

yeah i know about the temp thing i just was unable to remember the exact temp. As far as filling the top i did it once to the top and once short enough not to over flow. I was using a wine theif.

I'm 1 for 2 on hydrometers. Gravity just LOVES them for some reason

If someone made them prism shaped, I'd totally buy one. I keep knocking them off the counter.

The kids "played" with one, I've dropped two, and the cat knocked one off the counter. Fishin Dave is right, gravity sees a hydrometer like a tornado sees a trailer park.

I've broken two that I had laying around. Both on the same day. Luckily they weren't the ones I normally used, just extras from when I pick up good deals on craigslist.
