  • Test pool salt level- Salt range:0~9990ppm/10~100ppt; Essential for keeping your pool salt water concentrate at the correct level if you are using a salt water chlorine generator. Check the salt concentration of saltwater pool and hot tub that use salt chlorine generator; Help the salt chlorinator work more efficiently in the appropriate salinity value.
  • Test the pH level of pool- pH: 0.00~14.00; Recommend pH level between 7.2 to 7.8 according to different type pool (fiberglass; vinyl pools and tiled pools). When the pH is within range, for optimum performance and cleanest water.
  • Digital tester VS test strips- With strip tests, youll have to guess what pools value is based on the color of a strip; Digital tester, however, will give an exact reading so theres no guess work involved. Plus, using test strips enough will add up cost in the long run.
  • Multi-function salinity tester: ORAPXI 5 in 1 tester can measure Salinity/pH/TDS/EC and temperature level, suitable for all swimming pool, salt water hot tubs, spas, saltwater aquarium and reef tank.

Good quality manufacturing easy to use and accurate a must for salt pools

Pool Users: Great for salt level check, not so great for pH.
It is easy to use out of the box. It is very consistent with the salt level readings (I double-checked with a chemical tester and the difference was less than 100ppm, which is fine to check salt levels for a pool with a salt chlorinator). So worth to do salt level measuring - takes a few seconds and reliable. As for pH, you have to calibrate it frequently (it comes with the powder to do the calibrations), but becomes a hassle to calibrate and you never know if it is calibrate it or not. So I use the chemicals to measure pH (just more reliable and consistent over time). ... show more

Reliable
I have been using Taylor Liquid Test kits for a while because test strips always led me to wasting a lot of chemicals. I was looking for something that I could use everyday just to keep an eye on the quality's direction. This is it. Simple and nice to carry around and quickly check readings. It provides trends and it may not be as accurate as the Taylor Kits, but damn close. ... show more

Inaccurate Ph readings make a convenient product worthless
The ease of use of this meter for ph and salt levels as opposed to doing the chemical drop and color comparisons for ph alone is worth the cost of this product. However, as with any diagnostic test equipment, you have to have faith that readings you get from it are accurate. After repeated high ph readings with this meter and adding acid based on those readings, I finally began to suspect the meter was not reading the ph correctly. I then perfomed the chemical drop and color comparison test and got a reading of 7.2 as opposed to an average meter reading of 9.1. So, I decided to recalibrate the meter per the instructions using buffer packages included with the meter. The meter would not calibrate to the 6.8 buffer but read 9.18 which is one of the buffer test solutions. So I used andother pack of 6.8 buffer and got the same 9.18 reading. Conclusion is either the buffer packages are not right or the meter's calibration program is not working. Regardless, after just a couple of months of use, this meter is worthless to me because I have no faith in the readings. This was my second meter of this brand (first one got lost during the winter)and I really depended on it for my daily checks on ph and sale. Dissapointing! ... show more

Good price, great product. Saves time!
Works great. I will update review for longevity but I suggest getting a glass and put an inch of clean water in it. Keep the sensor immersed in clean water when not in use. The automatic pool controllers sensors look a lot like these and if they dry out they oxidize and lose their minds within days. If you do feel like it has lost accuracy the way to clean the automatic ones is a clean toothbrush and clean water... try same procedure. Like I said, I will update over time but so far it saves do much time just getting an instant read. ... show more

Handy for pool owners
Seems pretty accurate from what I’ve been able to verify. Definitely a nice tool compared to the salt tests with the pretty nasty chemicals I’ve used before PH is definitely nice to check with this. Good time saver.

Finally another reference point.
Was getting really lost between pool supply store reading, the different strips, and the controller sensors. Mostly on pH and salinity. Pretty cool device. Be patient, calibrate and it does the magic.
