Wide Range of Application Area—pH Salt Water Pool Testing Kit
Wide Application—-YINMIK YK-5 Digital pH Meter and Salt Tester
1.Nice pH Salt Tester Kit for Pool—The pH level of pool water is a measure of its acidity. The ideal pH level for pool is 7.2-7.8 , salt leverl is 2700-3400ppm. Maintaining a saltwater pool requires regular testing of pH, salinity, and total alkalinity levels, occasionally cleaning the salt cell. Ideally, you should test pH twice a week and salinity and total alkalinity at least once a month.
2. Good assistant for aquarium lovers—With YK-5 pH Meter for auqairum ,even if you are a beginner, you can easily take care of your fish. Normal pH Levels for freshwater fish is 5.5-7.5, for salt water fish is 8.0+,the salt level for saltwater fish is 26-35ppt. Detecting water parameters accurately such as nitrates and pH levels are fast and easy with this Aquarium test meter. With just a single pH Meter enables you to test your water accurately and keep your tank clean and maintain a safe environment for your dearest water pets.
3. pH Meter for Water Hydroponic—Suitable pH and EC Values for Your Hydroponic Nutrient Solution. Behind every thriving plant is a gardener who cares for her carefully. Through this 5 in 1 PH tester, you can easily grasp the environmental factors of plant growth.
4. Water Tester for Drinking Water—Testing your water using a TDS meter is the simplest way to measure for total dissolved solids. If you have a reverse osmosis system, you can use the following formula to calculate the percent rejection of TDS and to measure your RO system’s performance. TDS Calculation Formula:%Rejection=Tap TDS-RO TDS/Tap TDS*100 Example:TDS = 260 ppm RO TDS = 20 ppm Rejection = [(260 – 20) / 260] x 100 = [240/260] x 100 ≈ (.923) x 100 = 92.3. Generally, the TDS level between 50-500ppm is considered as the most suitable and acceptable. TDS levels below 50 can be considered high-quality drinking water.
Note: If the content is less than 80ppm, it is called soft water; if the content is between 80ppm-160ppm, it is called hard water; if it is above 300ppm, it is called very hard water.

Great tool for the price
Still figuring some of it out, but it works good.I use it mostly for the p.H and solidity or salt level.And so far that has been on mark I compared it to the pet stores equipment and it was very close to the same reading, it seems like a good tool for the price

Pool stuff
Really nice and easy way to test my pool. For the important things it needs.
AGWright –
Works well
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.

Lost accuracy within a week
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.
Amazon Customer –
Works well and is super-easy to use.
Yes, it takes time to read the instructions and figure out what is what on this meter, but once you do, you will be glad you did. It works well and we are getting good readings on it (we used a pool company test to verify before trusting the readings). The results were right in line with the professional test results.That said, I have one complaint which is this item should come with the appropriate fluid to protect the probe itself. Found out after my purchase that I needed a solution to keep the sponge inside the cap moist and clean. This product should absolutely not be sold without this preservation fluid included. It cost me $15-19 dollars to purchase the fluid separately to preserve the probe so I bought a backup probe that came with 2 bottles of the preservation fluid for $19. It annoys me but the item itself works and I want to keep it so that was my choice.

Marketed for salt pools and spasâ¦..not really.
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. Itâs not expensive, but itâs 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 wouldnât recommend it for a supplemental reading for PH levels.It is easy to use and when calibrated, gives instant results.

It works as should
Good product

UPDATE – METER WORKS PRETTY GOOD, GREAT VALUE
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.
Manon Groulx –
Fonctionne super bien.
Bullfrog –
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.
Chris R. –
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.
keith ho –
I like the structure and functionality of this product.
V. Evers –
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
