QA Instruments Conductivity Standard 12880uS/cm 200ml

• Calibration of conductivity meters – Instruments that measure electrical conductivity in water (such as EC meters, multiparameter probes, salinity testers like the Apera Salt20 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.

Supplied in 200ml bottle.
