SALT-3000 Meter, Digital Salinity PPM Temperature Tester for Salt Water Pool and Koi Fish Pond

Per the Product description, this TDS-4 TDS Meter (Made by HM Digital) has been calibrated at 300x10 ppm TDS (using a water + salt calibration solution). Thus, it has been given a new part number - TDS4TM-3000. TDS does not mean Total Dissolved Salt, but if you add enough salt to tap water to have 3000 ppm, this meter will read about 300x10 (3000). Nothing in your pool water will add more than a few hundred TDSolids, so you can rely on this meter to give you an accurate measurement of salt in your pool (ppm), may as well call it a salt meter. Yes, you can use any TDS meter to read your pool salt ppm, but as stated on the manufactures' website and on the packaging, the standard TDS meters are only calibrated at around 342 ppm. Your pool needs to have about 3000 ppm for the SWG to work correctly. Your digital meter should be calibrated with a standard that is close to the value you wish to measure (in our case, 3000 ppm) If you opt for a cheaper meter, be aware that it may not be calibrated to read at the 3000 ppm range accurately. Because of the 3000 ppm calibration, this meter will work great from around 2500 to 3500 ppm (salt), but don't expect it to be very accurate at low values, like for your tap water. TDSMeters.com has a pretty good explanation of how TDS meters work, and how they are calibrated. Photos of the product are attached, showing all the literature that comes with it. The meter arrived quickly thanks to Prime Day!

Needed for a salt water pool. Works perfectly as described. Easy to use.

Came as promised and appeared to be accurate.

So simple to use and so very accurate. Made a good construction and very good quality. Lightweight beautiful to look at it very easy to read. Gives an instant reading and you can wash it off very easily afterwards. It is a necessary item to have if you own a pool. You cannot depend on your salt cell generator to tell you the amount of salt this thing confirms it and gives you an accurate reading.

Not a happy camper on this one. Died after 3 weeks. New batteries no help. Return policy is ship back to vendor at self cost. For $20, I'll just buy a different meter.

Works well. Great price. This is not the waterproof version. But as long as you don’t drop it in the pool you are okay. I leave it inside the house, and go out to the pool with a cup and bring a cup of water inside to test. Also, I keep a bottle of water with in, because it says to rinse the sensor probes with bottled water after use. I give it a quick pour with a couple tablespoons of bottled water, so the same bottle of water lasts a long time. Great value for this model. If you are going to store it outside in the pool area, then I’d recommend getting the waterproof version. But if you are storing this inside, then you can save some money with this non-waterproof version. Seems to be very accurate compared to the professional test at the local pool store.

Aug 10, 2020 Used salt meter for my pool as prescribed once a week for three weeks and it worked great, then it wouldn't turn on for the fourth week. Tried changing out batteries and it didn't fix it. Attempted to contact eSeasonGear and they would not respond to any of my messages. Very bad customer service for a defective product. Since it also passed the 30 days of purchase Amazon has no options for returning it, so I'm out of luck. Update Sept 30, 2020 eSeasonGear finally got in contact with me and let me know that if the meter is not displaying any information than I need to take the batteries out for 2 hours to let it reset and then put the batteries back in. That actually seems to have fixed it, so hopefully there will not be any further issues. They also let me know that there is a 1 year warranty with the product. Really wish they would have gotten back with me before I ended up purchasing a second (more expensive) meter for my pool from another seller.

I purchased this for my salt water pool. I have to drive 30 to 40 min. Away to have my water tested. I have been having issues with my salt cell so I wanted something to be able to check it my self. I read the reviews and they were great so today I checked it scared it was not accurate because it did not match my salt cell reading. Very frustrated I got my sample and went to pool place. It was the same number this little tester had. It was not a few hundred off it was the exact same number. I was so surprised and excited! I wish I would have gotten this years ago! Great product! You will not regret you got this inexpensive pool salt tester! I don’t usually review items but just had to give my rave on this tester! Thanks for such a great buy!

Simple to use. Does the job

Should have had one years ago for treating my koi pond , when doing a partial water change you can’t accurately know how much salt is in the pond without a meter like this.

It is not very accurate

Don’t buy - stopped working and only used it once!

Easy to read, works very well
