Bluelab EC 2.77 Calibration Solution - 250ml

The 2.77 EC solution is used as a checking reference to ensure you have adequately cleaned the EC/CF probe.

All Bluelab 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 to check that cleaning has been successful.

Aim to clean and test your EC product every 30 days. Refer to the Bluelab website at www.bluelab.com for step-by-step guidelines for cleaning and care.
