A single-use 20 mL sachet of Milwaukee's lab-grade pH 7.01 buffer — the neutral reference point used to calibrate any pH pen, meter, or controller. Accurate calibration is the difference between a reading you can trust and one you can't, and 7.01 is the standard starting point for nearly every pH device. The sealed sachet keeps the solution fresh and shielded from air and light, so you get a precise, uncontaminated reference every time, with no measuring, no mixing powders, and no worrying about an opened bottle drifting out of spec.
To use, simply tear open the sachet, dip in your rinsed probe, and follow your meter's calibration steps. For the best accuracy — especially in planted tanks where you're tracking pH to dial in CO2 — pair it with our pH 4.01 buffer for a full two-point calibration. Certified to ±0.01 pH.
