After 3 busted glass hydrometers the last couple of months I can't tell you how glad I am this is here. It just arrived today and I popped it into some 60* tap water for some calibration and it was spot on at 1.000. I was worried it could be off being made of different materials than glass, but that worry was put to rest today. Thanks a ton NB!

Snapped at the join where bottom meets top
Well... I had high hopes for this product, but alas it failed on my third use. I had to bust out my glass hydro to do the job.

It snapped at the join where the top meets the bottom. Maybe I had a defective unit, but I can only comment with what I'm given.

As it stands right now, I would not recommend this product as being superior to a glass hydrometer. They are pretty much on equal grounds of fragility at that segment of the unit.

Well constructed and accurate
Right out of the box I tested filtered water at 60°F and the reading was spot on 1.000 and to me that's all you can ask for from a hydrometer.

The construction is sturdy and I don't feel like it's delicate like other hydrometers on the market.

It appears to do the trick!
My last hydrometer fell to a linoleum floor, and my heart was broken. This one, though, appears to be invulnerable to my clumsiness!

tough but not accurate
I haven't broken it yet but it is also off by .004 with distilled water at 60f. I also seem to get very different OG compared to two different refractometers even after adjusting for temp and the .004 offset. The refractometers are hand held units so they also can be flawed. I need to test compared to lab grade unit to determine which and how much each unit is off.

Response from Northern Brewer
We are glad to hear that you like the toughness, and hopefully never need to buy another Triple Scale Hydrometer. There is generally a bit of an off-set in triple scale hydrometers and the readings will be constant to help with any calculation adjustments necessary. If you are looking for more precise readings from your hydrometers, we would suggest the Brewery Essentials Advanced Testing kit which contains 3 narrow-range precision hydrometers that will deliver pro-quality results. Yes, we hope to have a Herculometer set of precision gravity reading hydrometers in the future.

Shatterproof but still breakable
This came to me reading .097 in tap water at 68F. Not too big of a deal, you just add .003 to the readings.

Sadly this fell once from a height of 4ft thanks to a nice gust of wind and broke where the bottom bulb meets the top shaft. It's a small crack but it allows water into the bulb causing it to take on fluid and alter the reading. The only benefit to this was that there was no glass to clean up.

Minus 1 star for breaking, and another for improper calibration.

Just received and used this hydrometer. After breaking 2 glass ones I thought this was a good idea. It's a shame it doesn't have a thermometer contained.

Good product not great
I used mine for the first time yesterday and I think it may be off by a little because of it being made of plastic and not being perfectly straight. Still works well just make sure you test it out first and gauge if there will be any difference in yours.

Now I have a tool my dog hasn't broken since I've got it. It's there when I need it and that's fortunately been a lot. Thanks N.B.

Does this hydrometer come with a test tube? If not, what is the recommended size (volume / depth) of test tube for this particular hydrometer?
A shopper on Dec 27, 2016
BEST ANSWER: no, it does not. the bulb of the hydrometer measures .7" i use a cylinder that is 11.5" high and 1.125" in diameter. i fill about 9" full, in order to float above the trub. it uses about 4-5 oz.
what size test jar is needed?
A shopper on Jan 9, 2017
BEST ANSWER: Hi there,
Any of the test jars we sell will work with this hydrometer. Cheers!
When will you be releasing these polycarb hydrometers in lab grade ranges?
A shopper on Dec 12, 2016
BEST ANSWER: Hi there,
We have just released our Precision Scale Herculometer! Product numbers are 42042, 42043, and 42044. Cheers!
