HI7031L | Hanna Conductivity Buffer Solution 1,413µS/cm - 500ml

Calibrate your EC meters with confidence using the Hanna HI7031L Conductivity Calibration Solution, the industry-standard buffer for general water quality analysis in Pakistan. With a conductivity value of 1413 µS/cm (1.41 mS/cm) at 25°C, this solution is the perfect reference point for measuring freshwater, drinking water, agricultural run-off, and hydroponic nutrient solutions.

Manufactured under strict ISO 3696/BS3978 guidelines and traceable to NIST standards, the HI7031L ensures that your readings remain accurate and defensible. The 500 mL bottle features an air-tight, tamper-proof seal to preserve freshness and a detailed label with a temperature correlation chart, allowing for manual compensation if your meter lacks an automatic temperature sensor. It is the essential "daily driver" standard for keeping your conductivity probes in top condition.

Frequently Asked Questions:

Q: Why is 1413 µS/cm the most common standard?

A: Most freshwater sources (tap water, rivers, nutrient mixes) fall within the 0 to 2000 µS/cm range. Calibrating at 1413 µS/cm places the reference point right in the middle of this range, ensuring high linearity and accuracy for the vast majority of water testing applications.

Q: Can I dip my meter directly into the bottle?

A: We strongly advise against it. Dipping a used probe into the bottle introduces contaminants that will change the conductivity of the entire supply. Always pour a small amount into a clean beaker for calibration and discard it afterward.

Q: How long does the solution last?

A: Unopened, it has a shelf life of up to 5 years. Once opened, we recommend replacing it every 3 to 6 months to prevent errors caused by evaporation or slight contamination from the air.
