best water tester

The issue of having clean water at home is crucial. Many install water filters while others simply disregard the problem as they don’t find it to be urgent enough. We like to be safe and facilitate the most ordinary things, so today let's talk about water test kits and water testers, which are devices that allow verifying the suitability of water for domestic use. We’ve picked the best water testers in the following two categories out of over 3500 Amazon.com products: 

Why Do You Need a Water tester?

We have already devoted a review to the devices for controlling water quality, personal waters filters. However, no filter is perfect as in the course of time solid particles accumulate on it and if you neglect maintenance, these particles will be found in the water. Most often the owners of cheap filters which let the solid particles into the cleaned water become the victims of this. Does the water have a suspiciously unpleasant odor and color? The National Environmental Services Center scientists name the sewer smell, chlorine smell and taste, rotten egg smell etc. to be the most common complaints. The latter smell means that the water contains hydrogen sulfide, which is quite unsuitable for use. Chlorine smell indicates high content of this substance in the water.

Some cases are less obvious and it is impossible to detect harmful elements in the water without thorough analysis. Water test kits will help you be on guard all the time. There are two types of them for drinking water: a pocket tester and a water test kit allowing for a complex analysis and suitable when an unpleasant odor is detected.

The device will also be useful to test pool water, especially if you have children. Once you’ve checked your pool with such a tester, you might be horribly surprised to learn how many unwanted elements have settled there. Water test kits for complex analysis (standard tests include Chlorine, Bromine, pH, Acid Demand and Total Alkalinity tests) are used to control the quality of pool water. That is why if you want to avoid some nasty diseases, you won’t do without a water tester.

How Does a Water Test Kit Work?

Any portable water tester measures the number of solid particles found in the water (total dissolved solids – TDS) in PPM (part per million) within the range of 0 to 1000 (or sometimes 10 000) PPMs. The higher the figure is, the less appropriate the water is for drinking. The acceptable range is 100-300 PPMs. The filters of most complicated designs are able to infiltrate 0-50 PPMs water. At 600 PPMs the water will have bad taste. The functionality of a pocket tester is not limited to measuring TDS though. The device is a bit larger than a thermometer and can fit your pocket so you could easily use it along with a portable water filter when hiking or camping.

A water test kit is a more complicated device. As a rule, it contains a set of special reagents which will help you remember you high school chemistry class lab experiments with a litmus stick and test the water quality with the help of a simple manual. Of course, you can also test the water quality with a pocket tester, but remember that there exist special tests for drinking water and pool water and mere hardness of the water will tell you nothing.

4 Best Water Test Kits for Drinking, Aquarium and Pool Water

Do you need to check the quality of your drinking water filter? This isn’t a problem. For these purpose we’ll find a home test kit for you. Testing the pool water quality is mandatory, especially if you have children who can accidentally swallow the said water. You won’t do with a regular tester here, as a special water test kit for a complete analysis is required. The water quality matters even for the fish in your aquarium, so we’ll find water test kit for that as well.

Below we’re going to list 4 most popular options: chemical reagent sets for Chlorine, Bromine, pH, and Acid Demand testing as well as total alkalinity measurement. For the fans of simplicity we’ve been able to find some handy disposable strips for detecting disease-causing bacteria such as E.coli, Staphylococcus Aureus, Salmonella.

Water Test Kit for Bacteria - AquaVial Water Test Kit for Bacteria

Water Test Kit for Bacteria

Metal particles aren’t the most dangerous thing to encounter in water. If we’re speaking about open water sources, the bacteria possess most danger there. Many testers aren’t aimed at working with the bacteria, so you’ll require a special test kit for this purpose.

This ~$17.99 set contains three test kits: for bacteria, biofilm and fungi. Obviously, there is no information regarding water hardness, so the kit is really a mono-functional one. This is helpful in terms of both testing the pool water and the filters (it sounds like a good idea to test the water before going camping in order to avoid some despicable consequences). The only thing this kit lacks might as well be a portable case to transport it without any issues.

#1 Best selling Aquarium Test Kit– API Freshwater Master Test Kit

Best selling Aquarium Test Kit

This kit is a real aquarium water test station. You won’t do without it if you have a large aquarium with lots of fish there. The design is similar to the pool water testing kit. The main distinction is that the tests for the habitable water are supposed to be different. The home station will test your water for pH, High Range pH, Ammonia, Nitrite & Nitrate and will indicate the time to replace the water.

Unfortunately, no large flask is supplied as the manufacturer decided to only provide 4 test tubes. Should you be rational enough, you’ll be in no need of a huge bowl though. The manufacturer claims that the kit will endure up to 400 tests given that the recommended dosages are used. By the way, the manual is clear, straightforward and will let you carry out the analysis even if you failed chemistry in school.

This is a #1 Best Seller in the Aquarium Test Kits category on Amazon.com. Read over 1400 customer reviews to see for yourself that it is popular not in vain.

You don’t like messing around with the test tubes, do you? Below we’ll describe the best pocket water testers which are appropriate to use in any situation.

The Best Pocket Water Testers

A pocket water tester is irreplaceable when you’re on business trip or hiking. If you doubt whether some apparently clean water is drinkable, use this gadget to learn the truth. It will help you test pool water as well, but more profound analysis will require ones of the water test kits mentioned above.

The Simplest and Most Accurate Pocket Size Water Tester – HM Digital TDS-4 Pocket Size TDS Tester Meter with 0-9990 ppm Measurement Range , 1 ppm Resolution, +/- 2% Readout Accuracy

The Simplest and Most Accurate Pocket Size Water Tester

The two main qualities of a portable tester are simplicity and precision. The HM Digital product has both these features of decent quality, hence its rank of a #1 Best seller in the Lab Multiparameter Meters category on Amazon.com.

The device can measure PPM within the range of 0 to 9990. You might wonder, what is so difficult about making it 10000. The answer is that 9990 PPM is indicates horrible quality of water (we honestly hope that you never encounter such water) as the recommended level of total dissolved solids in drinking water is only 100-300 PPM.

The interface is as simple as it can get: there is an on/off button and the indices retention button. The latter is especially helpful should you carry out the measurement in the least convenient conditions and you need to be memorized.

The item costs ~$15.89, this isn’t the cheapest price, but it is justified by the quality of the design and the precision of the device’s operations. Read over 600 customer reviews to learn more advantages of this product.

A Protective Case Water Tester – Digital Aid Best Water Quality Test Meter 0-9990ppm

A Protective Case Water Tester

This tester is identical to a best-selling one. It also has the maximum capacity of 9990 PPM; it has the same productivity and shape. The main difference is in having another screen mode, the shift mode which lets the device memorize and compare the figures. There is also a hold button and a leather case supplied. The latter will be found handy by those who go on business trips often, as the case will protect the tester from wearing out and damage while being transported. The item is a bit more costly, as it is quoted at ~$23.47, but you needn’t worry about the justification of the said price as the users attest to the high quality of this device’s operation in the comments section.

The Most Popular with the Users Tester– HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range , 1 ppm Resolution, +/- 3% Readout Accuracy

The Most Popular with the Users Tester

We can’t but recognize this device among the best Amazon pocket testers. It has been present on the market for quite some time, proven by years of use; it has over 2400 customer reviews and a rating of 4.4 stars out of 5, which is impressive enough.

Why do the customers find it so attractive? Apart from its high rating, the device can boast of a wide PPM range (0-9990) and an average price tag. It is a bit below the price of a best seller, but isn’t the cheapest one either. The slight disadvantage is the increased 3% error, which is 1% higher than the previous devices have.

A Cut-Rate Water Quality Tester – ZeroWater ZT-2 Electronic Water Tester

A Cut-Rate Water Quality Tester

Do you need a reasonably-priced tester in case you forget to replace the filters? This item has been designed just for you! It will only cost you ~$19.98 and will perform all of the necessary basic functions.

What does it lack? The most obvious thing is that its TDS measurement range has been reduced to 999 PPM. You won’t need any more for home use. It is highly not recommended to consume 700 PPM water, to say nothing of the higher figures. The materials are a yet another cost-saving aspect. Why pay more, if your tester is a tool that is stored most of the time on the shelf?

The measurement precision is comparable to that of the top device. The same holds true for the minimalistic «on/off and hold» button functionality. This is a quality option for those who like to save money.
