Liquid pH test kit
Most of Bluelab?s EC/ppm equipment does not need calibrating as they are all factory calibrated here at Bluelab (except Bluelab EC and ppm Pens). The 2.77 EC solution is used as a reference or checking solution to ensure you have adequately cleaned the EC/CF probe.
To ensure solutions remain accurate:
Decanter into a smaller plastic cup
Discard sample after use
Store in a cool dark place
Store with lid secured tightly
Keep out of reach of children
Bluelab solutions are manufactured specifically for Bluelab products are NIST certified and are made to a traceable standard to ensure your Bluelab products last longer and maintain accuracy.
