HY-GEN pH Buffer 4 – The Precision Calibration Standard for Professional Growers
Tired of unreliable pH meters ruining your nutrient balance? HY-GEN 4 pH Buffer delivers laboratory-grade accuracy for calibrating pH meters at the critical lower range (pH 4.0) – ensuring your readings stay pinpoint accurate for optimal nutrient uptake.
Why Proper Calibration Matters
✔ Avoid "False pH" Readings – Prevents nutrient lockout from miscalibrated meters
✔ Two-Point Calibration Essential – Must be used with pH 7.0 buffer for full accuracy
✔ NIST-Traceable – Batch-tested to ±0.01 pH tolerance
✔ Stable for 6+ Months – Unlike homemade solutions that degrade
How to Calibrate Like a Pro
-
Rinse Probe – Use distilled water (never tap)
-
Dip in HY-GEN 4 pH Buffer – Adjust meter to exactly 4.0
-
Repeat with pH 7.0 – Ensures linearity across range
-
Verify Weekly – Drift = contaminated probe
Pro Tip: Store buffers in airtight glass – plastic absorbs CO2 and alters pH!
HY-GEN vs. Cheap Buffers
| Feature | HY-GEN pH 4.0 | Generic Buffers |
|---|---|---|
| Accuracy | ±0.01 pH (NIST) | ±0.1 pH (unverified) |
| Stability | 6+ months opened | Degrades in weeks |
| Contaminants | Ultra-pure reagents | May contain phosphates |
| Usage | 50+ calibrations | 10-15 before drift |
