Description
Keep Every pH Reading Honest
Essentials LAB Buffer pH solutions are calibration fluids for checking and adjusting a pH meter's accuracy, sold as matched pH 4 and pH 7 references so a meter can be calibrated against two points rather than one. Essentials is VitaLink's own entry-level brand, matching the same trusted formulation behind VitaLink's own buffer solutions, and pairs directly with the Essentials pH Meter already in the HCS range.
A meter drifts over time, especially with regular use in nutrient solution, and calibrating against a known buffer is the only way to know a reading is actually correct rather than just consistent. Running both a pH 4 and pH 7 buffer gives a proper two-point calibration across the range most growers actually work in.
- Matched pH 4 and pH 7 buffer solutions for genuine two-point meter calibration
- Same formulation lineage as VitaLink's own buffer solutions
- Pairs directly with the Essentials pH Meter and other digital pH pens
- Keeps feed dosing accurate by keeping the meter reading it against honest
How to Use
- Calibration: dip the probe in pH 7 buffer first, then pH 4, following your meter's calibration routine
- Frequency: recalibrate regularly, especially with daily nutrient-solution use
Technical Specifications
- Type: pH calibration buffer solution
- Variants: pH 4.0 and pH 7.0
- Use: digital pH meter/pen calibration
