PH reader is grossly inaccurate and will not calibrate

I'm still hesitant to keep the tester just for the ORP reader which is easy to set up and accurate. Once it was possible to calibrate correctly. Then I checked my two aquariums. I first ran a chemistry test on both the liquid and the ProScan strip. The large tank has a PH of 6.5 and this reader returned 7.28. My other tank is also 6.5 and the racer gave me 8.1. I tried to recalibrate but failed 3 times so I gave up on the PH part.

Pros
  • Range: 0~14.00pH; -1999~1999mV; -50~70°C / Resolution: 0.01pH; 1mV; 0.1°C / Accuracy: ±0.1pH; ±5mV; ±1°C
Cons
  • Requires socket

Cannot complete calibration

I bought this because there are more pros than cons. And for the price. I just didn't expect it to be so difficult to work with and understand. For the beginning; The instructions are vague for the first time user. Second, to start the calibration, you must immerse the meter in the proposed liquid and wait for a stable reading before proceeding. If you can watch the video I posted you will see that the reading has not stabilized and we are moving to the third day. Yes, it is in the same 7.0…

Pros
  • Comes with ATC, measurements are very accurate with a unique stability indicator right on the LCD
Cons
  • Damaged

A good pH and ORP reader

I wanted to know the facts about the local tap water as well as expensive bottled water. The counter worked perfectly and delivered good readings. I also calibrated the meter against known pH values of various waters and water sample values, which worked as expected. Tap water has always been around 7.5ph. Good handy tool, handy mounting box and easy to read display although I would have liked it to be a bit bigger. But reading in an ordinary house or in the sun is NOT stressful. The ORP…

Pros
  • A waterproof meter to measure pH, ORP and temperature simultaneously
Cons
  • There are other interesting options.
