pH 7.00 Calibration Solution 500 ml

Unlock Your Pot-tential with pH 7.00 Calibration Solution 500 ml

Neutral pH 7.00 is the critical midpoint for every accurate calibration in South African hydroponics, coco, soil or fertigation systems — hard water, alkaline drift or temperature changes can skew readings fast, causing nutrient lockout, poor uptake or wasted fertiliser before deficiencies show. The pH 7.00 Calibration Solution 500 ml delivers a generous, NIST-traceable buffer (exactly 7.00 at 25 °C) to anchor reliable two-point calibration for pens, handheld meters and controllers. Temperature-compensated values from 0–60 °C allow precise adjustments for your grow-room conditions (e.g., 7.01 at 20 °C, 6.96 at 40–60 °C). Close tightly after each use to maintain stability, and store between 15–25 °C away from sunlight — no contamination when handled properly. The 500 ml size provides excellent value for frequent or daily calibrations across multiple devices like the P50 Pro2, P110 Pro2, P160 Pro2 or C800 Pro. Sustainable, high-precision calibration that keeps your pH locked in the optimal 5.8–6.2 zone for maximum nutrient availability, healthier roots and bigger, better-quality harvests.
