Pool Salt Tester & pH Meter - Digital Salt Water Pool Tester 5-in-1 Salinity pH Temp EC TDS Meter for Saltwater Pool, Hot Tub, Aquarium, Hydroponics, Drinking Water, High Accuracy Digital Pool Tester

I was skeptical as the tester was electronic and would be difficult but was very easy to set up. Power it on and use the buffer powder with water to calibrate it. Take about few minutes to be done setting up. Calibration just takes few seconds. I have used paper tester before but finally got to know the exact parameters. It’s great.

not accurate

The instructions contain information for all the various models they offer, with a check mark in the model you receive.You get three packages of varying pH packets with no instruction on how to use them. Do I Mix them in water? How much water? Pool water or other? Where do I get more of these packets?I wanted something simple to use, perhaps rechargeable or that uses standard batteries, not multiple button cells. It just seems very clunky, and overly complicated to even understand the operation. I just want something I can push a button to turn on, stick it in the pool water and get a reading.This is not that. I'll be sending it back before I use any of it. Maybe the next person will have the time to understand it, unlike me.

I have a pool, and I take care of it myself. It's a salt pool, which means that the chemical reaction that creates chlorine from the salt in the pool slowly raises the pool's pH as a by-product of that reaction. I have to monitor the salt ppm and the pH at least weekly. The recent summer storms have overflowed the pool, lowering the salt ppm and requiring me to add some..So, here's this meter, which promises to watch both of the things that I care about. The meter arrived packed well in a plastic tray in a box, which likely provides enough protection for the meter during shipping. I pulled out the directions and also found three packets of pH bufferring solution for the purposes of calibrating the pH meter. Awesome. I mixed up the powder acording to the directions, in just over 8oz of distilled water. Our distilled water is kept in the garage and it's summer, so it was a little warmer than the 77 degrees, so I cooled the calibrationbn solution down in an ice bath to exactly 77 degrees F. What's cool is that the meter recognizes each bufferring solution (6.86, 4.00 and 9.18) and long-pressing the mode button calibrates the meter to that specific solution. It's easy.I was going to calibrate the other functions of the meter (TDS and salt) but the necessary buffer solutions were not included. They are available on Amazon for $12 each from another vendor. Okay, I can always get them later..I rinse out the glass measuring cup that I've been using to calibrate the meter and fill it full of pool water., The meter reads just a little over 8. No, that's wrong - I keep it below that, so I grab my Taylor kit and pour a sample from the glass cup that I just tested. Sure enough, it's between 7.6 and 7.8, according to the wet phenolphthalein test that I run every week. I took a photo of the result - it's kinda hard to see, but in person it is definitely berween 7.6 and 7.8..Did I do something wrong? I don't think so. I worked in an industrial setting most of my life where we regularly checked the pH of boiler water and such, and I've calibrated pH meters before. Our meters generally used two solutions, not three, but it was the same procedure. I then put the sample in the ice bath and cooled it to 77 degrees F exactly - no change on the meter. It's still reading .3 high. I change out the sample and try it again..... no change. Well, at least the results are repeatable..Should I calibrate it again? Well, I can't - the pH solution is all gone. I can buy more on Amazon for about $12. Nope. I gavr it a shot, invested my time and I have a meter that I can't trust. I can spend $50 on new buffer solutions and give it anotuer shot, but I think I'll just stick with my wet tests for now. It was a nice idea, but it's not working out..My thoughts on this are that it's a nice portable pH meter, and even if I DID calibrate it wrong (don't think that I did) I'd still have to spenbd $36 on buffer solutions ($50 if I want to recalibrate the pH) in order to use the meter as advertised. If you are in a lab and you have this stuff on hand, this might be a great thing, but I don't think that I'm going to get much use out of it.

I make hot sauces, and an important aspect of food safety for this type of product is achieving the proper pH to ensure safe, stable shelf storage. Of course, the key to this is being able to reliably check the pH of a batch of sauce along the way, as it's being made, and right before bottling. Some people use pH paper for this but I've always preferred the much more informative results produced by a pH meter.I've wanted a second, backup unit for some time, so when I saw this PUREFIZ Digital Salinity Meter and PH Tester for Pool Water and Drinking Water which does so much more than my plain vanilla pH meter, purchased nearly three years ago and at double the price of this one, I had to have it.Although we don't have a pool, being able to check the quality of our tap water from time to time is a huge added benefit of this meter, to me.Unlike my "old" pH meter, this one arrives without a plastic storage case or pre-made pH calibration standards. The lack of a case isn't a deal breaker for me and calibration standard solutions have a relatively short shelf life once made up. This PUREFIZ meter comes with three envelopes of dry powder for mixing up calibration standard solutions (for pH 4.00, 6.86, and 9.18). As a side note, these envelopes resemble drink mix packets, so should be kept away from children. As these standards and the points the meter is set to be calibrated to are not the usual pH 4, pH 7, and pH 10, if you already have these, only the pH 4 standard will be of use in calibrating this meter.The included instruction booklet is informative but the "centerfold" consists of a "parameters" chart which has important information but the print is "microscopic" and impossible to read with unaided eyes. This and the odd choice of calibration points, mentioned above, are why I deducted a star.As for the actual operation and performance of the meter, it's very straightforward and the calibration procedure is easy.I cross-checked this PUREFIZ meter against my existing meter for pH (the only thing they both measure) measurements and the pH readings were in perfect agreement, i.e., identical.Things I really appreciate about this meter, compared to my "old" one, are that the crystal clear, easy-to-read display is backlit (invaluable!) and the pH readout is to two decimal places. That second place isn't really "significant" but it's useful for getting a faster idea of "which way the wind is blowing" when making serial adjustments to the pH of whatever you're working with.All in all, I'm happy with this meter and am comfortable recommending it.

Good pool tester.

Works as advertised. Good tester if you know what you are doing. It was a stepper learning curve that expected for me. But result seem to be correct once I figured out what I was looking at. Nice tester overall.

It’s compact and easy to use, with a clear digital display that gives accurate readings for pH, salinity, temperature, EC, and TDS. Having five tests in one device is convenient and saves time. The readings are reliable, though the battery life could be better if used frequently. Overall, it’s a good, all-in-one option for pool and spa maintenance.
