Rugged and Accurate
I read the reviews and almost didn't buy it because some said it was not accurate. I have had 2 of the fragile ones, and no matter how hard I try not to, I keep breaking them. This one is much more durable and I have found it to be just as accurate as the fragile glass units.

it works
It works like it should! I haven't tested how sturdy it is, I am just assuming it isn't going to break if an accident happens. I am Happy!

Unbreakable sure, but offset adjustment keeps drifting
It's unbreakable as advertised but the calibration is definitely a bit off. I've had and broken several glass hygrometers and they've come in pretty darn close to 1.000. This was 0.095 in water from the get go. Not ideal to have to keep adding 0.005 but if it didn't break that would be worth doing the mental math. Now it's continuing to drift and comes in at 0.085!! I guess there's a leak and some water is getting in and making it float lower and lower. Soon it won't be usable unfortunately. Hopefully this one was a dud but I'm tempted to go back to glass and replace them every couple years!

I have had opportunity to use the herculometer just once. It seems a bit more heavy duty than hydrometers I have used previously. Since it made of polycarbonate, I am hoping it stands up to the minor dings that do happen during use, and stays intact.

Lasts more than 1-2 readings!
I'm a terrible klutz. For many, many years, I have avoided using a hydrometer because I hate buying one, using it once or twice, and then it touches the counter the wrong way and shatters into a million piece.

It's great to have one I don't have to tiptoe around. Works beautifully!

Not as durable as expected
Worked fine for 3 batches, but when I went to take a OG rating on my 4th it came apart. Somehow small cracks developed where the 2 parts meet. I'm not sure how, I never dropped it and treated it with the same care I would a glass hydrometer.
Because I brew in my kitchen and don't want to risk broken glass, I'll buy another, but probably the 2 precision ones next time.

It broke
I've broken enough glass hydrometers to be really excited about this and bought two!

One of them had the plastic cap come off, flood with beer when I was shaking a fermentor, and sunk. When I took it out, I also found out that the body and base can slide right apart... they didn't appear to be glued or bonded in any way.

The second one I have is still going.

It would be great if hydrometer manufacturers would all disclose whether they're using lead, tugnsten, or steel balls. I just had a glass one break and after some detective work figured out it was a solid lead bottom. I'll only be buying steel or tungsten ones in the future for obvious reasons.

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.

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: My test jar is 12" long and 1.125 ID. I pour five ounces of beer in it to bring it up to a good height. Northern Brewer has a similar test jar in stock, # 6396. Happy brewing.
what temperature is this calibrated to? I lost the stuff that came with it.
Aedan R on Aug 3, 2017
BEST ANSWER: Thanks for contacting Northern Brewer. The Herculometer is calibrated to 60 degrees. Cheers! -Deanna, staff
does it test moonshine?
A shopper on Jul 23, 2017
BEST ANSWER: This hydrometer is designed for only beer and wine. Cheers!
Is it dishwasher safe?
A shopper on Jun 6, 2017
BEST ANSWER: No idea. I don't put anything brewing related in the dishwasher. Sorry
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!
How well does this respond to high/low temps? Can I put in 200F wort to grab a post mash temp reading? Could this be the issue some folks are having with leaking and busted ends?
