2 in 1 Salt Tester Digital Salinity Meter with ATC Salinity and Temperature Meter Waterproof IP67 Pen Type Salinometer ppt Aquariums, and Koi Fish Pond for Saltwater Seawater, Hydroponics, Water, Pool

The accuracy and easy of use is excellent. The salt water cell in my pool system is completely unreliable, but this tool is amazing. No more over salting the pool. I highly recommend.

Very easy to use and read. Changing from Deg C to Deg F took some digging in the user manual, but was straight forward. I assume the calibration is good out of the box. I will post additional review if it turns out otherwise. Used to check salt level in pool.

The meter seems to give accurate readings after following directions to set up which can be complicated. It is necessary to dip the probes in a solution or distilled water before and after use. 30 mins prior if you haven’t used it for a while. I don’t care much about the temp settings so I didn’t bother checking it for accuracy. I only care about salinity to measure my pool water. There are steps to follow and ranges for proper calibration if needed. It takes 4x LR44 batteries which I must have in storage in case I run out. I remove it after using to make it last.

The salinity tester seems to work well. I tested tap, RO, ice maker, and outdoor spigot water looking for traces of salt. My main focus was outdoor spigot water, hoping I was not watering outdoor plants with low levels of salty water, slowing killing those plants. Whew, the outdoor water is fine, as is the rest of the water around the house.Finding no salt in all my testing, I dissolved some salt in RO water and tested again. Yep, there was a measurable concentration of salt. Nice. I am confident in the tester and the results, though I may never use it again. I will probably just keep the tester and loan it out or give it away, sort of a 'pay it forward' effort.The tester was boxed and package well. I did install the batteries backwards on the first try, so watch out for that. The selector buttons take a little time to figure out, just press and release in normal use and to turn on/off. Do not press and hold unless entering a special function.Nice tool and I am glad I ordered it. Thanks!

I am unable to verify product is working. Water reading with my refractometer shows my sg at 1.025 the calibration of that device was completed before my reading. This device shows 1.021, which is a vast difference in a saltwater aquarium. Seller wants me to replace the batteries with new ones and attempt again. Their instructions are tough to figure out, and calibration is confusing. Supposedly you use a solution to calibrate but no solution is provided, and I cant even find it to buy on Amazon. Not at all confident this device works properly.

I am using this to measure the salinity of my girlfriend's blood for home hemo dialysis and Im getting PPM readings about 1000ppm lower than her lab results from the same day.I attempted to recalibrate it but according to the destructions, it only lets you go 20% higher than its calibrated for out of the box. It says that if the calibration is more than 20% off (which I cant guarantee its not due to the fact I'm measuring blood not straight pool water) it should be replaced. Well I just got this thing and doubt it needs to be replaced so soon so maybe its my fault. Either way it doesnt read blood properly so dont try it.So 3 stars I gueeeess? I dont want to be too negative but I cant be too positive either.

No need for more expensive testers. This does the job effectively. We live in a marshy area where salt water incursion into our irrigation ponds is a problem and reliably determining the salinity content of the water is crucial.

not what my wife exxpected
