Bluelab EC 2.77 500 ml, calibration solution

To ensure the continued accuracy of your Bluelab EC meters, we recommend cleaning and testing them regularly.

All Bluelab EC pens and meters are calibrated at the factory so you do not need to recalibrate them. Instead, you should clean the Bluelab EC probe and then check if the cleaning was successful using Bluelab 2.77 EC Standard Solution - 250ml.

You should try to clean and test your EC meter every 30 days. All Bluelab products come with step-by-step instructions on cleaning and care.

Bluelab 2.77 EC Standard Solution - 500ml is essential for use with all Bluelab EC products.
