easy to use, good for home use.

I bought this tester package for testing my home RO water system, as I am wondering the timing to replace the filters. The tester is simple to use. As I compare the testing result with other water source, I think the reading is accurate, good enough for home usage.

Warranty included. Great product.

Good product. Product comes with warranty for 120days! Considering I broke last one with in 2 weeks. And this product the battery’s worked out of box vs my last ph meter purchased on amazon.

Much better than those paper strips

I used to monitor the PH value of the tap water in my house by using those PH strips made of paper, but after trying for a while I never felt their results were accurate nor reliable. For this reason, I switched to something that's more advanced, that's this product. As many have mentioned, the meter is sensitive enough to give very accurate results and it is also very easy to calibrate. At this price for two meters, I think it is very reasonable, as I spent almost the same price for some useless paper stripes for what I really regret...

Good value, on prime day.

We’ve had a fancy RO system for a while now for drinking, making coffee and cooking and it came with a TDS meter, but this was on a prime day deal and comes with a PH pen too. Our RO system has a cartridge that is supposed to add minerals back in and adjust the PH, so I figured why not? Time will tell!

pretty satisfied

I purchased a drinking water system early this month from APEC company, I forgot to order water test meter. Choose amazon instead to order test meter since lower free shipping standard and including both TDS and PH meters. They have 3 different buffer powers to ensure its accuracy. The instruction is detailed wit the steps.

Helped me to monitor water quality

It looks accurate and I'm glad that my RO system works like a charm! The water is about 300 in the tap in my area, and after the filtering, it is less than 20! Used Costco bottled water and it is even lower. Good meter.

Store the pH meter with a wet spongue. The TDS meter can NOT measure hardness.

First, the TDS "hardness" meter (reads PPM). This device only measures conductivity, which is NOT a measure of water hardness, or measure of unknown ions. It can be useful ONLY if you ALREADY KNOW all the ions (sodium, calcium, magnesium, etc.) present in the sample you are measuring. The PPM number displayed is just the conductivity multiplied by a constant that assumes the sample contains only calcium chloride ions. If you have a water softener and use the TDS meter on the softened output, it will tell you that your soft water is much harder than your hard water! This error is because a TDS meter measures the (soft) sodium ions in the soft water, but the instructions tell you that the reading is in (hard) calcium ions. (There are practically no calcium ions in softened water; the softener took them out!) To a TDS conductivity meter, ions are ions. You have to know which one(s) you are measuring! If you're testing tap water, you also have other ions like magnesium (which will be "double counted") and probably iron. If you want to know the hardness of you water, use a test strip (+/- 15% accuracy) or reagent kit (the best are +/- 2%, most are 5%). (These numbers are from a company that sells expensive precision water test equipment, so they are probably "worst case" numbers used in marketing.) Note that test strips generally measure only the calcium ions, but hard water generally has others like magnesium. The hardness reading from a test strip may effectively be low because it doesn't look for these other elements. Ask your water company for their general analysis (the EPA makes the provide it to you), or if you have well water, have a lab analyze a sample. (The well driller may also know, based on where they found water). Use that to learn what's in the sample you will be testing, and then use ratios and valances to interpret the TDS (conductivity) reading. --- Finally, the pH meter. When stored, the bulb is best kept damp with a buffer solution of about 7.5 pH. You can make one with a little vinegar and baking soda. User your meter to check the pH after you stir in more vinegar (reading too high) or soda (reading too low). Then fit a very small piece of sponge into the bottom of the cover, and put a few drops of the buffer on the sponge -- damp, not sopping. Too much and the cover won't go on or the excess solution will be forced up into the meter. The tightly applied cover will keep the buffer from evaporating, the pH meter will keep better calibration, and the bulb will last longer. Rinse the bulb in distilled (or deionized) water after taking the cap off so the buffer won't get into the sample want to measure. Also, don't worry about re-calibrating your meter unless you're paranoid, or the readings seem unquestionably off. Store it wet at neutral pH, and it will be very slow to drift out of calibration.

But unfiltered water seems to be worse than a year ago

What I need is the TDS meter. We have a filtering system installed a year ago and the technician tested the filtered water with his meter. I want to keep test it again to see what the difference now and determine whether to change the filtering columns or not. Tests result showed there is hardly any change for the filtered water. But unfiltered water seems to be worse than a year ago. The water qualify of Houston is declining....because of the Hurricane? Good to know though. Anyway, overall satisfied with this purchase and will recommend to friends.

After a few times of calibration it works great. Now I can decide to drink tap water ...

I had to watch YouTube tutorial before calibrating and using it. Just wanted to make sure that i did it right. After a few times of calibration it works great. Now I can decide to drink tap water or not.

Great for home use

Works great. I bought it to measure the pH and mineral content for my distilled water that I am making at home. Super easy to calibrate as needed. For example, I add trace mineral supplement (LYTEtrace) to my distilled water for 150 ppm and 7.0 pH (neutral water) - the coffee brewing is just out of this world! My tap water was 383 ppm and the chemical sludge they add, the coffee was sour/salty tasting. Not anymore!
