Description
QA Instruments Conductivity Standard 12880uS/cm
-
Calibration of conductivity meters – Instruments that measure electrical conductivity in water (such as EC meters, multiparameter probes, and water quality testers) need regular calibration against known standards to ensure accuracy.
-
Widely accepted reference point – 12,880 µS/cm is an internationally recognized conductivity standard, especially used in environmental monitoring, hydroponics, drinking water testing, wastewater, aquaculture, and laboratory analysis.
-
Traceability – These standards are prepared using high-purity salts (often potassium chloride, KCl) and deionized water, and they are traceable to international measurement standards (e.g., NIST).
-
Application range – A solution of 12,880 µS/cm corresponds to water with moderate-to-high ionic strength, similar to brackish water, process water, or nutrient solutions. It’s typically used when working with mid-to-high conductivity samples.
👉 In practice, if you’re measuring things like nutrient solutions in hydroponics, brackish water, or industrial wastewater, you would calibrate your meter with 12,880 µS/cm so that readings in that range are most accurate.
