Great for pH meter

Really good value for money and seems to give a reliable reading. Has a nice little instruction manual and pockets to make sure it's calibrated, but looks great straight out of the box and has a sturdy plastic storage box.

Pros
  • Cool product
Cons
  • Some little things

Works great for the money.

Works for what I need it for. Not 1000% accurate, but very close. I need water around 7.0 and it shows between 6.8 and 7.2. So I have about 3 or so. Near enough. If you want absolute accuracy, pay 4-6 times more for a high-end device.

Pros
  • High marks for support and durability from testers
Cons
  • Can be damaged

not enough information before buying

I bet it's a good counter. The description explained the calibration process, but for some reason I missed the information about the need to calibrate before almost every use. I got 2 good readings after setting it up, then air registered 16 and water registered 0. I would buy a calibration solution or other method if I had all the information I need.

Pros
  • great price
Cons
  • expensive insurance

never mind Not as accurate as I would like.

Fine. It's not that accurate and I've never been able to calibrate it for 4.01 packs even after I bought more thinking I'd screwed it up. But I need absolutely accurate results as this is for an aquarium. The test strips and liquid tests I already have are more accurate. I wanted something I could get a quick answer from. So 7.5 is on the meter like 8.2, which can mean death if the tank is set incorrectly.

Pros
  • Great for a small home
Cons
  • No machine

Inaccurate even after calibration

I used 3 test strips from different (manufacturers) and they were MUCH more accurate. Very high scores for that. So much so that I've drained my hot tub twice. I calibrated twice with the supplied solution and distilled water. After calibration, it had lower readings until I tried again. Don't waste money. Also, you need to leave it in the water until the gauge stabilizes, which may take a few minutes. It cannot be left floating, so you must always keep it. Test strips 2 seconds. Buy a good…

Pros
  • Fingers crossed
Cons
  • Vulgarity

Easy to use, works accurately, takes some getting used to

I don't want to become a chemist to take care of our pool and I appreciate tools that are easy to use, calibrate and use. It was easy to use, with pretty clear instructions.

Ready to use - would/could not calibrate

This PH meter was broken right out of the box. I immediately followed the instructions to rinse and dry the sensor head and calibrate the meter using the supplied calibration powders/solutions. The calibration package labeled "6.5" didn't bump the counter to 6.5 - it's calibrated to 4.1. The calibration package marked "4.1" simply made the counter blink continuously even after tens of minutes of waiting. I immediately rinsed everything and repackaged it for return. This product wasted my time…

Pros
  • AUTOMATIC TEMPERATURE COMPENSATION (ATC). You can get an accurate water pH test result without worrying about the effects of water temperature.
Cons
  • Socket required

WARNING!: pH meter

This gauge cannot be calibrated. I'm not new to using/calibrating pH meters. I used the attached solution which didn't work and also used my own solutions. You would expect some margin of error with this type of product, but after all calibration attempts it showed a pH of 7.5 with apple cider vinegar, 9.2 with white vinegar and 11.5 with distilled water. My baking soda solution had a value of 2.8! These types of gauges are never entirely accurate, but you should be able to calibrate them…

Pros
  • SMALL SIZE AND POCKET PORTABLE. It's small and light like a pen, easy to carry and convenient to carry in your pocket when you go out.
Cons
  • Expensive
