Frequently Asked Questions
1. How do I choose the right conductivity standard for my meter?
You should select a standard with a value close to the expected range of your samples; for the best accuracy across a wide range, perform a multi-point calibration using two or more standards.
2. Why is temperature important during conductivity calibration?
Conductivity is highly temperature-dependent, typically increasing as temperature rises; for accurate results, always allow your standards and probes to reach thermal equilibrium, ideally at 25°C.
3. Can I reuse conductivity calibration solutions?
No; used standards can easily become contaminated by the probe or atmospheric CO2, which will alter their nominal value. Always pour a fresh aliquot into a clean beaker and discard it after use.
4. What is the shelf life of a conductivity standard after opening?
Shelf life varies by concentration; high-range standards may last several months, but low-level standards (10 µS/cm or lower) are highly vulnerable to CO2 and should ideally be used immediately after opening.
