Pool Salt Tester & PH Meter, Hofun Digital Salinity Meter and PH Tester for Aquarium and Pool Saltwater Water, 5 in 1 Salinity PH Temp EC and TDS Meter, Aquarium Swimming Pool Hot Tub, High Accuracy

If you own a salt pool, you know the frustration of trying to reconcile what your salt cell says versus what a test strip shows. I bought this Hofun digital meter to help dial in a new Hayward salt cell, and it has been a total game-changer for my maintenance routine. ​Pro-Level Accuracy: The biggest win? I tested this meter against multiple other readers and even took a water sample to Leslie’s Pool Supplies for a professional lab test. This Hofun meter was spot-on right out of the box. While it comes with calibration materials, I didn't even need them—it was highly accurate from the first dip. ​Performance Highlights: ​Instant Results: No more "color-matching" strips or waiting for drops to react. You get a clear digital readout in seconds. ​Salt Cell Setup: It was instrumental in getting my new T-15 cell up and running. It gave me the confidence to know my salinity was perfect before I fired up the system. ​Easy to Use: The interface is simple, and the build feels solid enough to live in a pool kit. ​Verdict: If you’re tired of the guesswork and want a reliable tool that matches the pros, this is it. It’s the easiest way to keep your salt levels and pH in the "green zone" without the headache.

If you're a pool owner looking for a convenient and reliable solution for testing salt and pH levels, look no further than this fantastic device from Hofun.

Works as described. It matched my Pool Service Person's salinity meter. I like that it is multi-function, but I mainly bought it for checking my pool's salinity level. I previously was using salt test strips (AquaChek). Those were unreliable and costly over time. Plus they have an expiration date. This doesn't tester have an expiration date and will pay for itself over time. If it does get out of calibration they include calibration medium to reset it.

While we thought the salt readings were accurate, we took our pool water for full comprehensive tests at a store, over several weeks, and this reader was never accurate (read salt at 3500 when it was really 2900). We tried to calibrate it, but the calibration wouldn't work: we couldnt adjust it and it would just default to ms/cm, but not actually change. For most saying it's accurate, I believe they just read the device and have no other professional comparison. However, we may have also just gotten one that wasnt working properly. I was outside my return window, but the customer service was great at helping me. Rated a 4-star for the customer service reaching out and trying to make things right.

Great salt level tester. Easy to use and understand. A critical piece to any salt pool owner and relatively inexpensive. I have not attempted to use the PH tester.

I bought this thing around two years ago, but didn't get around to using it until recently, after draining our pool to do some work on it and then refilling it. If I had bought it less than 30 days ago, I would be returning it for a refund. I'd give zero stars if I could, because it cannot be trusted. Our pool is a salt water pool with salt chlorine generator, and I wanted the tester mainly for testing salinity, but also for the temperature, pH, and total dissolved solids (TDS) functions. It came with three packets of powder to mix with 250 ml of distilled water each to calibrate the pH at three different levels. After doing those calibrations, it seemed to agree nicely with the chemical pH color test. However, it didn't come with the necessary solutions for calibrating the electrical conductivity (EC). The TDS and salinity functions are based on the EC. Without EC calibration, I was getting salinity readings in the ballpark of what I knew they should be, but always somewhat higher, based on the known volume of the pool (12,000 gallons) and the known quantity of salt I added (360 lbs). The salinity should be right about 3600 ppm, but the tester tended to read usually closer to 3700 or even more. The worst part is the TDS always read around 100 ppm LOWER than the salinity. TDS includes salt, as well as calcium, total alkalinity, CYA, and any other solids that have been dissolved in the water, so it should always be higher than the salinity. My TDS should be reading around 4100 or so. So I purchased the necessary EC calibration solutions and did that calibration. After doing that, the TDS and salinity readings of my pool water are even higher than before, with TDS STILL LOWER than salinity. What's more, doing that calibration broke the pH reading. Prior to doing the EC calibration (maybe an hour before), I got a pH reading of about 7.7, which, again, agreed pretty well with the chemical test. After doing the EC calibration (which should NOT have affected the pH calibration), the tester gives a pH reading of 7.2 or less on my pool water, and it is telling me that the pH of distilled water is between 5 and 6, which is ridiculous and impossible. (It should be about 7.)

Very happy with purchase very easy to use for a newbie. Really helps me with my salt percentage which is so important to keep koi alive and healthy. Would definitely purchase again is accurate user friendly

Does not work as needed for saltwater aquarium... it doesn't measure specific gravity (which I missed) but it is also advertised for a fish tank so thus the 3 stars. It does seem to work as long as you know the PPM - PPT conversion to get to specific gravity. BUT on the specific gravity I read that if you measure it in PPM or PPT that will not translate well back to SG so it is best to get a tester for that.

It's ok

I have been using this to test the ph in my hot tub for a month now. It is extremely accurate (comparing to two different test strips) and it is extremely easy to use. I would not hesitate in buying this.

Easy to use and accurate.

Results for salt ppm very close to expensive test strips and very close to my pool chlorinator +/- 350ppm. A must have if you own a salt water pool. This would have saved me having to spend an extra $500 in water after I raised my salt level to just over 6000ppm thinking that my aging salt cell was reading correctly. My salt cell showed 2200ppm and I trusted it and added more salt...mistake. I had to remove 8000 gallons of salt water and replace it with fresh clean water to bring the pool down to 4000ppm so my chlorinator would come on and do its thing. I should have purchased this unit sooner. I've since replaced my aging salt cell with a new one and it reads within +/- 350ppm of this unit so everything is finally back on track.
