BLUELAB 2.77EC Conductivity Standard 500ml

Description

Bluelab 2.77 EC Conductivity Standard is a precise reference solution from the same brand as the pH 7 Calibration Fluid, used to verify the accuracy of Bluelab EC/PPM meters and probes. Key Features It measures exactly 2.77 EC (or 2.77 mS/cm) at 25°C and is NIST-traceable for lab-grade reliability, helping maintain probe performance after cleaning. Unlike pH solutions, most Bluelab EC devices are factory-calibrated and use this as a check standard rather than for full calibration. Usage Guidelines Clean your EC probe first per Bluelab instructions, then immerse it in a small amount of fresh 2.77 EC solution; readings should match 2.77 EC if accurate—repeat cleaning if not. Available in 250 ml or 500 ml sizes, store in a cool, dark place and test monthly for hydroponics or nutrient monitoring.
