EC 1413 Calibration Solution 500 ml

Unlock Your Pot-tential with EC 1413 Calibration Solution 500 ml

Reliable EC calibration is non-negotiable for South African hydroponic, coco and fertigation growers — hard borehole water, evaporation and temperature changes can cause meter drift, leading to inaccurate nutrient strength, overfeeding, root burn or wasted fertiliser. The EC 1413 Calibration Solution 500 ml delivers a generous, NIST-traceable standard at 1413 µS/cm (1.413 mS/cm) at 25 °C to keep your EC pens, handheld meters and controllers calibrated accurately at this common mid-range reference point. Temperature-compensated values from 15–30 °C allow precise adjustments for real grow-room conditions (e.g., 1386 µS/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 devices like the P110 Pro2, P160 Pro2, E300 Pro2 or C800 Pro. Sustainable, high-precision calibration that ensures your nutrient EC stays spot-on and your harvests reach full pot-tential.
