Can I use the test on several water samples or is it a one time use?

One time use, but for multiple tests. I bought 2 kits so I could test at my meter and after my osmosis.

Each test within the kit is for a one time only use, each testing different things.

Sure it can test any water. You just need to know what your levels need to be for the spa

Not two of every test. Although it has been long enough I do not remember which test was just one. In short you would need two kits for before and after.

no more than once per month, but it depends on how dirty your water seems i.e. residual lotions, perspiration, anti-perspirants, etc...

Technically, yes. There aren't enough cups and test tubes for each of them to do some of the investigations so they would have to share. I think there are plenty of chemicals to do the investigations more than once, but most of them are probably things you have in your kitchen anyway or can easily purchase (baking soda, vegetable oil, citric acid). This kit does require a lot of adult supervision. You won't be able to just turn them loose with it.

In my opinion, yes. It comes with advice that you can use to detect dissolved solids in the water. Use it with your tap water and then check water from the filter to see the difference.

Yes, two different units and use different strips. The Next is the more recent unit. I've used both and they work well. I think the Next may use a slightly smaller sample.

There are kits that can be used several times but I believe this one is a one time use. I have not needed to use mine yet (knock on wood) but they do give a 100% guarentee. I bought this after my daughter dropped her Blackberry in the toilet for the 3rd time and after her ipone I wanted to be prepared.

I use my test strips a while after I dump in the spa chemicals , say a few days. Everything seems to work fine though it is good to check periodically depending on the frequency of use, I guess.

I believe yes, there is. These are not a super high quality test so there is the possibility of false results. There are 10 in the box though, so you can have the tester take 2 at a time.

I work in the lab thats why i can check the quality of my water from this filter. In my community this filter can last for 4 years. By the way I have a pre filter connected to this unit. The life of the filter is subjective to the water quality and your usage. Take an optional water quality testing.

There were 2 tests for several different molds, but could only be used one time each. So you couldn't do any additional tests in additional locations.

I would definitely use a cup. I use those bathroom water cups you can buy like 200 of for a few dollars. The test strip is quite small, only has a small area that should be immersed for 3 seconds, and has another area which is not supposed to become wet.

Oh yes. I think maybe ten tests of each type? I tested at least 4 areas of my lawn and had a lot left over. The chemicals are packaged like old-school pills that you pull apart to mix with your sample.

It's a test that will work on water, as opposed to tests that are specifically for urine, blood, etc...

no, there is only one test kit for each substance. You could only test two if you mixed them together and did it as a pooled sample.

You put the water sample in the small bottle, being careful not to spill the powder in the bottle, fill to 1/2" below the top (cold water side), shake well, place on shelf and in 48 hrs, if it turns a yellow color, there's bacteria present, violet or blue, no bacteria. It does not tell you specifically which bacteria. Some reviews have reported a yellow/blue result, so it's inconclusive (my tests have all been pretty conclusive). If you get that, you might have your water tested professionally for a conclusive test. Only one test is included for each of the variants.
