Bluelab 2.77 EC Solution Sachets – For EC Meter Calibration

Keep Every EC Reading Trustworthy, Wherever You Calibrate

Bluelab 2.77 EC Solution Sachets give you a fresh, uncontaminated dose of 2.77 mS/cm conductivity standard every time you calibrate, without opening a full container you do not need at the bench. Each box holds 30 single-use sachets, so a travelling grower, a second grow room, or anyone calibrating away from the main supply, always has an accurate reference solution to hand.

Key Benefits

• 30 single-use 18ml sachets of genuine Bluelab 2.77 EC conductivity standard
• Tear-open pouches - nothing to reseal, no risk of a half-used container degrading on the shelf
• Prevents cross-contamination between calibration runs on different meters
• Compatible with any EC, CF or PPM meter - truncheons, pens, combo and guardian monitors alike
• Compact enough to carry between grow rooms or in a meter's own case
• Consistent 2.77 mS/cm reference point every time, so drift is caught early

Readings That Slowly Drift Off

An EC probe that has not been checked against a known standard for a few weeks will still give you a number - it just will not be the right one. Nutrient strength creeps up or down without anyone noticing until the plants show it, and the usual cause is a meter calibrated too long ago, or a shared calibration container that has itself become contaminated. A fresh sachet every time removes both problems at once.

How to Use

• Tear open one sachet and pour the full 18ml into a clean calibration cup
• Immerse the EC probe to the manufacturer's fill line and run your meter's calibration routine
• Use a fresh sachet each time - do not reseal or reuse a part-used pouch
• Calibrate weekly for meters in daily use, or before any critical reading
• Store the box in a cool, dry place out of direct sunlight
