YINMIK pH Salt Meter 5 in 1 pH TDS EC Salinity Tester for Pool Spa Aquarium Hydroponic Saltwater Digital pH and PPM Tester for Household Drinking Water Hot Tub Home Brewing Fish Tank…

I wanted to test the salinity in my tap water from my water softener before switching to potassium chloride from sodium chloride. This worked quickly and gave what appears to be an accurate reading. I also checked the water in the bottom om the brine tank to get a comparison and the difference showed up immediately. I was also able to see the ph readings as I cycled through the settings. The only quibble I have is that it's a bit hard to hit the scale button if you use a small vessel for your sample. But for the money, I would buy it again.

UPDATE: Vendor sent a new meter and temperature works much better. They tried a lot to want to make you happy. I found you can calibrate the EC part at ANY EC solution, which is the problem I had trying to follow the three EC calibration solutions. You can just calibrate it on a known solution near your target. Maybe I didn't understand the instructions. Check EC easily for my marine aquarium. Good Meter - get one! Original review: The Ph seems to hold after calibration for quite a while. The temperature is out off specs by 3deg F always. Salt readings should read 35ppt but reads about 27ppt. Other readings similar error. If I wanted a Ph meter only this would be ok as I have been using it for just over 30 days and past return date. I really wanted this to work and even contacted seller about out spec readings. Only good side is it is CONSISTANTLY WRONG so as long as you have a way to check the REAL values you can use it by comparing numbers. BUT can you trust it to stay that way. Read other reviews. Don't recommend this for aquarium use where these readings mean you tank is off enough to cause damage. YMMV.

This thing is fantastic. I love the simplicity of being able to check the salinity of the water with this tester! It makes it so easy and has been very accurate. I also like the quick function change to also check the ph! Way more accurate than test strips! Money well spent!

Es probador es completo, viene calibrado y también viene con manual y sobres de calibración, muy buena calidad.

It is marketed as a multi digital reader for a salt water pool. It reads PH, but I have had to recalibrate it weekly, in the less than 60 days of using it. It also reads salt in percentage and ppm, as well as the current temp. This device is better suited to an aquarium, not a pool or spa. It does not read water hardness, free chlorine, which is what the salt generator does or calcium levels to retain the free chlorine. It’s not expensive, but it’s not better than the chemical test strips and having to repurchase base chemicals to recalibrate weekly makes it better suited as a supplemental tester for salt levels. Since it would be supplemental and not likely to be calibrated correctly, I wouldn’t recommend it for a supplemental reading for PH levels. It is easy to use and when calibrated, gives instant results.

Easy and worked great

Readings were accurate and consistent for a few days and then it started making up crazy numbers. I had read warnings in other reviews but thought that rinsing it after each use would help. Nope, this is made for single use and then you either dispose of it or return it.

This is a must have when owning a saltwater pool. My last one was a basic model that measured salt and water temp, and it was a great help in maintaining good salt levels through the summer. It worked for many years, but it went toes up this past June and I upgraded to this newer model with more functions. I still haven't learned what 3 out of the 5 are, but I am now getting good salt readings and it's always nice to know the water temp. This one is more robust and seems to be a solid device, be aware though that it is NOT water proof so don't drop it in the pool when taking readings.

Fonctionne super bien.

This product comes pre-calibrated. It also comes with 6 PH calibration packages. It does not come with salt calibration solution. Ease to follow instructions for pools and hydroponics. Screen is very readable and easy to understand. Very easy to use. I use it primarily for PH and salinity testing of my pool.

This device is a must if you have a salt water pool. It's easy to use but save the instructions re calibration as this needs to be done periodically.

I like the structure and functionality of this product.

The devise works but sadly it is not any better the test strips. Needs to be reconfigured for alkalinity and other test. Sadl had to send back. Also, you need to take a sample in a glass and test. Strips are better
