Review on Optimized 0-14 pH Electrode Probe with BNC Connector, 300cm Cable - Suitable for PH Meter Monitor Controller Test Sensor, Ideal Replacement Kit for Aquariums, Hydroponics, Plants, Pools, and Spas (pH Electrode) by Theresa Brown
I don't have time to calibrate
The calibration has probably been kept for 6 months, I went to calibrate again, it's my own business. I watched the tutorials on YouTube 7x to make sure I didn't miss anything, changed the batteries. Still no bones. It just shows a 4.0 calibration no matter what and then when I calibrate it to 4.01 and it saves the data it IMMEDIATELY starts to drift in the calibration solution. For $40 I'm really surprised it lasted so long but I can't give it 5 stars for this performance.
- Certified
- The cable is shorter than other picks
