HY-GEN pH Buffer 7 – The Gold Standard for Precision pH Calibration
Is your pH meter lying to you? Without proper calibration, even the best meters drift over time—leading to nutrient lockouts, stunted growth, and lost yields. HY-GEN 7 pH Buffer provides laboratory-grade accuracy at the critical neutral point (pH 7.0), ensuring your readings stay rock-solid reliable.
Why Two-Point Calibration is Non-Negotiable
✔ Full-Range Accuracy – Calibrating at pH 4.0 AND 7.0 ensures correct readings across the entire 0-14 scale
✔ Prevents Costly Errors – A misreading of just 0.5 pH can lock out iron, calcium & phosphorus
✔ NIST-Traceable – Certified to ±0.01 pH tolerance (no guesswork)
✔ Long-Term Stability – Resists CO2 absorption better than cheap buffers
How to Calibrate Like a Lab Tech
-
Clean Electrode – Rinse with distilled water (never tap!)
-
Calibrate at pH 7.0 First – Adjust meter to exactly 7.00
-
Then Calibrate at pH 4.0 – Ensures linearity at acidic ranges
-
Verify Weekly – If readings drift, clean or replace probe
Pro Tip: Store buffers in glass bottles – plastic leaches chemicals that alter pH over time!
HY-GEN 7 pH Buffer vs. Generic Solutions
| Feature | HY-GEN pH 7.0 | Cheap Buffers |
|---|---|---|
| Accuracy | ±0.01 pH (NIST) | ±0.2 pH (unverified) |
| Shelf Life | 1+ year (opened) | Degrades in 2 months |
| Contamination | Ultra-pure salts | May contain phosphates |
| Cost/Use | $0.02 per calibration | $0.10+ (frequent replacement) |
