Hey Fernando,

Check out this link (click here).HM Digital COM-100 Waterproof EC/TDS/TEMP Meter

As you said, "Water comes before firearms, medicines and even food."

Here is another link to the same product (click here).Hand Held TDS Conductivity Meter

The second link has the following review:
I own a commercial water testing laboratory. This is the best portable conductivity meter I've ever seen and it has a very reasonable price.

Hi, that's pretty cool, I didn't even know these water testers even existed.
I found this other one that seems to be another good alternaitve for testing water quality.HM Digital Pocket Size TDS Meter TDS-4 Water Quality Tester
I'm not sure if it detects all sorts of micro organisms but it must narrow down nicely the sort of purity of water you are dealing with or how effective a filter actually is.
Product Description:

Carry one in your pocket at all times! .. The smallest and lightest TDS meter on the market. .. Sleek design is perfect for personal or consumer use. ...

Don't rely on a TDS meter for water potability. It is what it says - a total dissolved solids meter. Basically it detects salts and other minerals dissolved in the water. It does not give any indication of bacteria such as cholera, or viruses. If you are using ground eater, it could indicate if there is arsenic present - though it will not distinguish between arsenic and common salt - only tell you there is a presence of dissolved solids. Primarily, they are used as an indicator of acceptability of water with regards taste, etc. If you check on any website dealing with water quality, you will be given acceptable limits with regards TDS for drinking water.
