LivSure Water Tester

@waacodemon

as a wooter, i say buy 3.

Its on woot, it automatically has value

and if it doesnt work, then ya got your self a nifty door stop

and really

who doesnt need a door stop that may also be able to tell me if my drinking water is good

…

honestly!!!

WINNNNNN!!!
Yes in for 1, GF thinks their might be mold in her water and the landlord refuses to test.

[junkjunkie]

@ionoff

it means buy 3 but dont use them yourself except to see if your water can transmit electricity and at what resistance.

damn, I wasted my 50th post on you.

Do you transmit electricity?
Or conduct?

[SexConker]

This is kinda pointless…
It just sees how salty your water is.

In NO way should you use this as a serious tool to measure the quality of water.
The only real use this would have would be to test if your Brita filter needs replacing, but with the horrible accuracy (+/- 30 % once you hit 500 ppm), you won’t really learn much.

The thing just measures how much current flows between the 2 contacts (more dissolved solids = better current flow), and calculates a number based on the known volume of water (fill it up to the line VERY carefully, a slight error will totally throw off your readings).

Looks like a cool gadget, but I can find a better use for $10.

I was just about to jump in on this one for my Aquarium. . .

Anyone else notice the "Battery: Lifetime , AAA (included) " on the webpage URL posted earlier??? (http://www.livsure.com/water/water_tester.htm)

Would “Lifetime” in this case translate to “Not user replaceable”?

Does this mean once those two little batteries die, our fun is over???

I don’t think this thing would help anyone out camping. If you are backpacking and your only source of water is a stream, lake, river, spring, or other local water source your biggest concerns aren’t going to be about particulate matter. Once again, if you are heading to Mexico and want to avoid Montezuma’s Revenge, this isn’t going to help much either.

If you backpack, then you already know you need to boil your water. If you frequent Mexico then you already know you should stick with liquor.

Oh please. I don’t like Mexico much at all, but you can get bad water anywhere. Most touristy areas in Mexico use reverse osmosis trains to make their water. Reverse osmosis is pretty much the purest water you can get. Most bottled water isn’t that clean.
Where do you think the water in the beer came from?

[rebelman68]

I had one of these and stopped using it because it said my water was pregnant.

@jplonmars

95% of people who get sick from water is usually because of bacteria in the water. so i say if you boil the water from unknown source. you are probably 95% safer than if you drink it uncooked…

Boil not only kill most bacterias in water, it also get rid of chlorine (because Chlorine’s Boiling point is way below water’s so it vaporize way before water does.)

That why if you are in the wood (camping) you should always boil your water!

Another word…it won’t matter what this testing device is telling me…I will boil my water when I go camping…

I think drinking too much boiled water has a bad effect on one’s grammar…

[pavanb500]

Might buy this just for the shipping box…not sure what to get the GF for her bday…but I figured if I got a shipping container, I could just cut a hole in that box {omitted in order to avoid deletion}

[midiwall]

Gotta love the accuracy of this thing…

Testing Range … Accuracy … Resolution:
0~100 … ±3% … 1ppm
101~200… ±10% … 10ppm
201~500… ±15% … 10ppm
501~999… ±30% … 10ppm

TDS= Total Dissolved Solids
There are two ways of measuring it.
In the first:
weigh empty container
add a known volume of test water
evaporate to dryness
weigh again
That gives you the mass of dissolved solids per unit volume.
That’s how TDS is defined.

Here you use electical conductivity as a proxy for that.
If you know that you’re dealing with dissolved minerals that gets you there - to an approximation.

So this does not measure turbidity (cloudiness) caused by particulates or toxins (from algae) or fatty substances like hormones or even alcohol.

What it gives is a palatibility measure (the tongue-tip test is a good proxy for that) - stuff like agricultural fertilizer, salt, battery acid, bicarb… Like you couldn’t tell?

@jplonmars

As a scientists, I can tell you this crap doesn’t work.

There are 3 things that can kill you, physical, chemical and biological.

Okay, 4 things, add nuclear (radiation stuff)

This tester may test the physical stuff that’s not good for you such as salts, minerals but I doubt that it test chemical or bacteria stuff.

As a scientists ???

I doubt that it test chemical or bacteria stuff ???

you are more than one Scientist ? also you doubt that it tests Bacteria when it clearly states it tests desolved solids . what kind of Scientist are you anyway ?

[andrewkl]

so, if I test my water, and it is found to contain pharmaceutical waste and prescription drug residue, would the icon be happy or sad?

[whistl3r]

Completely worthless…

If you’re not sure about water; BOIL IT, before you drink it!

Seems to me that you suffer from a multiple personality disorder…

Why should we believe your assessment?

Depends on if the residue is Heroin or Xanax

That product description cracked me up. “An indian puking his guts out under a waterfall”

That is true comedy gold.

@TellarHK

Measuring the Total Dissolved Solids means almost nothing in regards to health of water. The real problems you need to worry about are things like bacterial contamination and giardia. A high number on a TDS meter looks worse than it could be, or might be telling you that you have only a VERY TINY amount of, say, uranium or mercury.

Useless without further followup testing performed by a professional.

@elmagico

This would be fun. I did my internship at a water desalination plant, to kill some time I’d test TDS at various stages of the plant as well as from bottled water etc… I know I’d mess around with one of these for at least a day or two…
What this is really doing is testing the conductivity of the water then converting it to TDS in mg/L or ppm.
The only real way of determining TDS of water is through evaporation with the use of a drying oven.

Chemists represent! I came in here to say this.^^^^^
After running tens of thousands of TDS (as well as TSS, conductivity, turbidity, free Cl, hex-chrome, etc.) tests as an environmental water/wastewater chemist, I can tell you: This thing is carp. It’s just a way to sell more filters.

Sorry, Woot, this one’s a loser.

Oh, and I’m guessing this is a joke:

@hawk0168

I drink DI water

but if not, you DO realize that DI will leach the calcium and other minerals from your teeth, right? You know: water, the universal solvent? Without the ions that naturally occur, it’s a bit less safe to drink.

[Solkre]

I could get the same readings as this thing with a flashlight and a clear drinking glass.

Exactly how many Scientists ARE you, and - although this is a water purity tester, it tests for more than just carp. There are many types of fish out there, my friend, don’t be so limited!

Finally, as W will tell you, it’s “Nucular,” my friend. That’s my final answer.
