pH 7.00 Calibration Solution 20ml Sachet

Unlock Your Pot-tential with pH 7.00 Calibration Solution 20ml Sachet

Reliable pH calibration is non-negotiable in South African hydroponics, coco, soil or fertigation — hard tap water, alkaline substrates and temperature fluctuations can throw off readings fast, causing nutrient lockout, root issues or poor uptake before you notice. The pH 7.00 Calibration Solution 20ml Sachet delivers a single-use, NIST-traceable buffer (exactly 7.00 at 25 °C) to keep your pens, controllers and handheld meters dead-on accurate. Pre-portioned 20 ml sachets eliminate contamination risks from reused bottles, making calibration quick, clean and trustworthy — tear open, dip the probe and calibrate in seconds. Temperature-compensated values from 0–60 °C let you adjust precisely for your grow-room conditions (e.g., 7.01 at 20 °C, 6.96 at 40–60 °C). Perfect for daily/weekly checks on devices like the P50 Pro2, P110 Pro2, P160 Pro2 or C800 Pro. Store between 15–25 °C away from sunlight — no waste, no cross-use errors, and full confidence that your pH stays in the sweet 5.8–6.2 range for optimal nutrient availability and maximum yields.
