All our conductivity pens and meters are factory calibrated, so you won’t need to recalibrate them. Instead, you should clean your Bluelab EC probe and then use Bluelab 2.77 EC Conductivity Standard Solution - 500 ml to check that cleaning has been successful.

You should aim to clean and test your EC product every 30 days. All our products come with step-by-step guidelines for cleaning and care.

Bluelab 2.77 EC Conductivity Standard Solution - 500 ml is essential for use with all Bluelab conductivity products. All Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy.

Bluelab 2.77 EC Conductivity Standard Solution is also available in 250 ml bottles. In addition, our Bluelab Probe Care Kits contain everything you need to clean, maintain and test your conductivity equipment, such as EC probe cleaner, a chamois and more.
