AquaMaster EC 12.88 Calibration Solution 100 ml
Ensure accurate and consistent readings from your EC meter with this premium calibration solution. Ideal for hydroponic, gardening, or nutrient solution setups, it provides reliable conductivity calibration so you can confidently monitor your nutrient strength.
Why this calibration solution matters:
-
Precise standard value: Calibrated to 12.88 mS/cm at 25 °C, the standard reference value for many EC meters
-
Traceable to NIST standards: Ensures your EC meter is calibrated against a globally recognized reference, giving accurate and repeatable measurements
-
Temperature compensation included: Conductivity values listed for a range of temperatures, e.g., 10.48 mS/cm at 15 °C, 12.88 mS/cm at 25 °C, 14.12 mS/cm at 30 °C
How to use:
-
Rinse your EC meter’s probe thoroughly with distilled water and dry gently with a lint-free cloth
-
Immerse the probe in the calibration solution up to the indicated level
-
Wait for the reading to stabilize
-
Adjust or calibrate your meter to match the standard 12.88 mS/cm reading at 25 °C per your meter’s instructions
-
Rinse the probe again with distilled water after calibration
-
Close the bottle tightly after use and store at room temperature (15–25 °C)
Perfect for:
-
Growers using hydroponic or soil-based nutrient systems
-
Anyone needing reliable EC readings for nutrient strength management
-
Users who want to calibrate EC meters regularly for consistent measurement and healthy plant growth
Keep your EC meter calibrated correctly so you always know the exact conductivity of your nutrient solution, helping you apply nutrients confidently and avoid under- or over-feeding your plants.
