Digital PH Water Tester, 5 in 1 PH/TDS/EC/Salt/Temp Meter, 0.01 High Accuracy PH Meter, Salinity Meter and PH Tester for Drinking Water, Hydroponics, Aquarium & Swimming Pool

I recently obtained the GISNPA 5-in-1 PH/TDS/EC/Salt/Temp Meter and I'm thoroughly impressed! As someone who monitors the water quality in my home for various purposes (drinking, fish tank, etc.), this meter has become a go-to tool in my arsenal. Here's why:Multifaceted Marvel: This meter truly lives up to its 5-in-1 billing. It accurately measures pH (acidity), TDS (total dissolved solids), EC (electrical conductivity), salinity (salt content), and temperature. No more needing multiple tools for different testing needs – this one does it all!Accurate and Reliable: The readings from this meter have proven to be consistent and reliable. I compared them with results from my local water supplier for drinking water testing, and they matched perfectly. This instills confidence in the meter's accuracy for other applications as well.Easy to Use: The meter boasts a user-friendly design. The large, clear display makes it easy to read the measurements, and the buttons are clearly labeled for intuitive operation. Even if you're new to water quality testing, this meter is straightforward to use.Great Value: For the price, this meter offers exceptional value. It packs in a multitude of testing functions, delivers dependable results, and is easy to use. Compared to buying separate meters for each test, the GISNPA meter is a cost-effective solution.Minor Musings: While the meter is fantastic overall, a carrying case for storage and protection would be a welcome addition.Overall: I highly recommend the GISNPA 5-in-1 PH/TDS/EC/Salt/Temp Meter to anyone who wants a versatile, accurate, and user-friendly tool for monitoring water quality. It's a fantastic value and has become a valuable asset in my home!Rating: 5 out of 5 stars

This is a good meter in that it can work to test 5 different parameters of water. I wanted it to test the level of salt in the pool and also to test the ph of aquarium water.It seems to work well for both of these tests but I did have to calibrate it as at first use it seemed to give me variable readings when retesting multiple times to test for accuracy.One thing that I found while trying to calibrate it is when pressing and holding the mod/cal button it would change to a different mode when first pressed so had to do it over a few times to get it to work.After calibrating it I tried retesting both ph and salt concentrations of a sample. If the tool is accurate it should repeat the readings and it did so within just a .01 to .02 difference each time. I think this is acceptable for my use.In researching the use of this type of meter I found information that the probe should be replaced every six months to maintain accuracy and if this is true then an ongoing expense is still there.

Upfront, I'll confess that I don't like ph testers and their need for the measuring solutions. Paper strips did not work for me so I went digital last year with a lower priced unit.I've learned what a big difference in taste and results the 'correct' ph makes with very different beer types and recipes. Got this unit to see if it worked any better than the quirky cheap meter I've been using. Time will tell. Quirky old unit is not consistent enough to compare readings/sensitivity with this new meter, so time (and taste) will have to tell. Most recent stout recipe is still fermenting. I'll be making a few different brews in the next couple months with different ph levels and the different additions to achieve levels required by the recipes.TDSI can vouch for the TDS accuracy.Tested my home RO before and after water samples with both old and new meters, were comfortably similar. Brought the new meter to my usual commercial RO supplier (also supplies the water for the commercial craft beer facility next door to them) and the supplier showed me TDS readings were very similar to her meter. They were very busy that day and were not interested in spending time to even consider the ph testing because of lots of paying customers waiting.So, I recommend this meter. Seems to work well. I'll probably purchase some new ph tester paper strips to see if they agree, but I feel I'm making progress.Recommended

Ok, so I wasn't expecting much when I ordered this but I wanted something better than what I had been using for my aquariums. Typically paper strips that read various parameters based on color change. Which never seems to match the shade that is present. What does it mean when my color shows brown but the scale is shades of red?I tried this out after confirming that it is pre-calibrated (so don't waste the calibration powders till you actually need them.I compared the results with the infamous test strips and I put far more faith into this meter than the test strips. After testing tap water, RO water and distilled water to confirm its working by being around 7 but varying slightly between samples, I proceeded to test my aquariums.It sure does pick out subtle differences between them for pH, temperature and TDS. My tanks read so close on the test strips I can't see a difference, but this meter does tell, and testing multiple times in various orders (plus distilled water wash between samples) I can say that it reads consistently for each tank.Well made and high resolution product. I can't comment on the accuracy, but its repeatability and precision are excellent. For what I need this is more than enough. Highly recommended!
