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

This one has few competitors. But it has a big advantage: 1. Fully submersible2. very accurate, pH, TDS, Temp.3. easy to move 4. easy to store 5. The pH lamps on all meters break from time to time - all use glass pH lamps but this model has a very easy to replace pH part with a replaceable lamp. So here's the big thing - you don't have to keep buying another one. 6. Sorry, but most importantly, pH is accurately measured in 0.1 increments. Cheaper testers only get level 1.0. They're cheaper, but not nearly as accurate. Buy a good product.
