Review on Hanna HI 98107 Precision Instrument by Stephen Johnson
Inaccurate after the agonizing calibration process.
Calibration was an absolute agony. And even after following at's instructions, it did NOT read the calibration solution closely, let alone anything else I put it into. The pH readings were also incredibly laggy and still inaccurate. I sent this product back, I didn't care if it was an accident.
- Two-point manual calibration for ease of use
- Slightly torn
