Review on 🧪 Hanna Combo pH/EC/TDS/C/PPM Tester HI98129: Reliable and Efficient Multi-Parameter Testing Solution by Crystal Taylor

After receiving this product, I tested it for about an hour and quickly decided to return it (mainly because it was defective, didn't give me a ppm reading.). As other reviewers have said, the reading takes a while to stabilize and it doesn't appear to be properly calibrated. When I came back to test the same water sample, I got a one point difference from the previous measurement. The first pH reading was 8.1, which I knew was inaccurate. Just before attempting to calibrate, I retested the same sample and got a pH of 7.4. After calibration, I got a reading of 7.1. Three different readings of the same sample. I've seen similar products from Bluelab sell for over $200 and have great customer reviews. Finally, I think you get what you pay for. Also, I'd like to take a look at the four star review published by Orion as they did a great job of explaining why this might not be the best option for you if you're considering using it as an EC meter.
