Bluelab 2.77 EC Conductivity Standard Solution 500 ml

Bluelab 2.77 EC Conductivity Standard Solution is the reference solution you use to check that your conductivity meter is still reading correctly. It has a known value of 2.77 EC (1385 ppm on a 500 scale), so you just need to submerge the probe and compare. It's the basic check to trust the EC readings from your reservoir. 500 ml presentation.

Benefits

• Known reference value: 2.77 EC, equivalent to 1385 ppm on a 500 scale.
• Manufactured to a traceable standard, for consistent readings across instruments.
• Also serves to confirm that the probe was properly cleaned after maintenance.
• 500 ml bottle, efficient for periodic checks.
• Compatible with Bluelab conductivity meters and probes.

How to use

Pour a little solution into a clean container and never submerge the probe into the bottle, to avoid contaminating the rest. Rinse the probe with clean water, insert it into the solution, and wait for the reading to stabilize before comparing it to 2.77 EC. Discard the used portion and keep the bottle tightly closed, cool, and away from the sun.

How to Use

• Pour a small amount of solution into a clean container — never immerse the probe in the original bottle to avoid contamination
• Rinse the EC probe with clean water and then immerse it in the 2.77 EC solution
• Wait for the reading to stabilize before comparing it to the 2.77 mS/cm reference value
• Adjust the meter's calibration if the reading differs significantly from the indicated reference
• Store sealed in a cool place, away from direct sunlight — discard if the solution becomes cloudy or contaminated
