The HI7031L 1413 µS/cm Conductivity Standard Solution is a premium quality calibration solution designed for accurate conductivity measurements in laboratory and industrial applications. Prepared using NIST traceable potassium chloride (KCl) standards, this solution ensures high precision and reliability for EC meter calibration.
Manufactured under strict quality control, the solution is standardized against NIST SRM 2202 in deionized water, following ISO 3696 and BS3978 analytical standards. Each batch is produced using certified balances, Class A glassware, and calibrated thermometers to maintain consistency and accuracy.
The HI7031L solution is supplied in a 500mL airtight bottle with a tamper-proof seal to preserve integrity and prevent contamination. The label clearly displays the lot number and expiration date, ensuring traceability and compliance with laboratory standards.
A temperature compensation chart is printed on the bottle, showing actual conductivity values at different temperatures, allowing users to achieve more precise calibration results.
With a long shelf life of up to 5 years (unopened), this conductivity standard is ideal for routine calibration of EC meters in laboratories, water treatment facilities, and industrial quality control processes.
