Works well and is easily replaceable
Iâve owned dozens of PPM/EC pens, meters and testers over the decades and this is the meter recommend for PPM. Itâs inexpensive and accurate enough for most homeowners or hobbyist. This has good clear readability and easy operation. Also just a coin cell battery so itâs light.PPM Meters all share one flaw â they are fragile and break easily! Expensive meters break just as quickly and easily as the inexpensive pens. They just arenât buy it for life products.A budget meter will give up some accuracy compared to more expensive meters on the market but, the budget meter is still plenty accurate for a home owner/hobbyist. When it fails after a year or two, throw it out and buy a new one.My only complaint is that it doesnât have a loop to attach a string to so I could hang it from a hook when not in use.

Very useful instrument. Works instantly and is easy to read.
A great TDS meter. I have use it several times with great success. I was able to see that my refrigerator water was sourced from my whole house water filter and not my reverse osmosis filter like I have seen done before in previous homes. I was also able to tell if my outside hose bib was connected before my whole house water filter or afterward. I was also able to see that my RO system was operating as it should. It works almost instantly. Just stick it in the water 🙂

Great for shrimp!
I got this product to know the tds levels in my shrimp tank. This product is really durable, especially because you use it in water, and it has a nice sleek appearance. itâs so easy to use with multiple different settings! I think itâs an important product to have if you keep shrimp, because they can be very sensitive to the tds in the water.

Affordable and Efficient Water Quality Testing
I bought the TDS Meter to measure the TDS of my RO filter, and itâs been quite useful. For the price, it offers excellent valueâcombining TDS, EC, and temperature measurements in one device. The large backlit LCD display makes it easy to read, even in low light, and the quick and simple one-button operation is a real convenience.However, Iâve noticed that the standard for indicating water quality with green for <40ppm and red for >40ppm might not align with all standards Iâm familiar with. Despite this, the meter still effectively serves its purpose for my needs. Overall, itâs a reliable tool for monitoring water quality. Also, I feel the meter is a bit bulky for its functionality.

3 in 1 tds, ec, temp water
Pros:First, itâs accurate for easy, which is the point why I need to buy this.I have a filter jug, tap water is 78 ppm, after filtered is 61 ppm. A small tip: the tds meter can also tells when to change the core of filter jug if you donât find any difference of filtered water anymore.Second, no calibration needed. Super easy operation. Turn it on and test, thatâs it.Third, the big LCD makes reading the numbers much easier. Green for ppm under 40, red for ppm over 40.Fourth, the chart at the back of the meter clearly shows which ppm level of my water.All you need to do is to test your water and compare the ppm with the chart. Then you can have a clear mind of your water quality level.Cons:this meter comes with a leather handy case. Since I never take it anywhere outside my house, it doesnât do much help to me. But maybe helpful for other people.All in all:After I have this tds meter, Iâm more aware of my drinking water quality as everything we take into our body affects our health, especially water. So itâs responsible for our health to check our daily drinking water.So far the quality is good, will update if anything new.

Works great, for a while….
This tool was a game-changer when I fist got it. Shrimp acclimation was so much easier. But after a year the battery didn’t seem to last as long, or the inside parts seem to wobble in the case. There’s lots of empty space between the breadboard and the case. So use it carefully, treat it gingerly, keep it in a protected place, not leaning against the shrimp tank or in a pile near the water testing kit. Maybe you’ll get more use out of it. I bought a different brand when I replaced it.

Its fun to know things.
My TDS meter makes me feel like a backyard scientist. ð± Distilled water comes in at 0 ppm, my Venus Flytrapâs self-watering reservoir sits at a perfect 2 ppm, tap water hits 176 ppm, and my home-filtered water measures 130 ppm. I mainly bought this to check on my Venus Flytrap, which lives outdoors on rainwater (with a little distilled top-up), but I never really knew what the solids were until now. The TDS meter is totally worth having for the peace of mindâand honestly, kind of fun to play with.
