Review on 🔬 Hanna Instruments HI98103 Checker pH Tester: Reliable and Accurate Testing with Ph Electrode and Batteries by Michael Freemason

After reading mixed reviews I took the plunge and decided to buy. I don't like the product. "This gauge needs to be recalibrated every time you use it." was in a review. Right. ALWAYS needs to be recalibrated. In fact, in many attempts I was unable to get the product to continue calibrating. "It can take up to 15-20 seconds for readings to stabilize." was in the same review. It's all up and down. So with calibration it would be correct. Given how I have to use the product multiple times a day with some other tests I need a product that is less irritating and more reliable. More quickly. This product is not for me. I use a different brand. This was supposed to be a backup, but when I needed it I desperately grabbed the pH tape. I will buy another backup model.
