EC 12.88 Calibration Solution 500 ml

Unlock Your Pot-tential with EC 12.88 Calibration Solution 500 ml

High-strength nutrient solutions in South African hydroponics, coco and fertigation systems frequently run 4.0–12.0+ mS/cm during bloom — but without accurate calibration at the upper end, your EC meters drift, leading to overfeeding, nutrient burn, tip damage or wasted fertiliser. The EC 12.88 Calibration Solution 500 ml provides a generous, NIST-traceable standard at 12.88 mS/cm (25 °C) to anchor high-range readings for trustworthy measurements. Temperature-compensated values from 15–30 °C allow exact adjustments for your grow-room conditions (e.g., 12.64 mS/cm at 24 °C). Close the bottle immediately after each use to maintain stability, and store between 15–25 °C away from sunlight — no contamination when handled properly. The 500 ml size offers excellent value for frequent or daily calibrations on multiple pens, handheld meters or automated controllers like the P160 Pro2, P700 Pro2 or C800 Pro. Sustainable, high-precision calibration that safeguards your crop investment and maximises bloom density, potency and quality.
