Review on 📏 Calibration Powder Included: Replacement pH Electrode, 0-14 pH Accurate Probe with BNC Connector & 200cm Cable for Continuous Liquid Measurement by Brad Schaefer
Reduce waste, save money
What a disappointment! I just wanted to control the pH. Received product with pH sensor floating in the box, no cap or cap on the sensor. . . THAT DOES NOT WORK ! . . . I can measure the same water 5 times and get 5 different readings + or - 3. Not 3 points but a full 3 ph deviation. SAVE YOUR MONEY! ! ! Why is there so much JUNK on Revain? LoL, the temperature sensor works great, but that makes it expensive.
- Test, measure and verify
- Ugly packaging
