Three Hanna conductivity solutions, 12880 μS/cm, 1413 μS/cm, and 84 μS/cm. The 12880 μS/cm is suitable for conductivity meters with a scale above 10 mS/cm. The 1413 μS/cm is suitable for general use, and the 84 μS/cm can calibrate instruments with a conductivity scale of up to 200 uS/cm.
The conductivity solutions are prepared against a National Institute of Standards and Technology (NIST) traceable Potassium Chloride solution. They are available in a 500ml bottle. Each label shows the product batch number, expiry date, and a conductivity/temperature correlation table. EC value is calculated at 25°C.
