Product Description

The Bluelab EC 2.77 Conductivity Standard Solution is a reference fluid with a fixed conductivity value of 2.77 mS/cm (EC) used to check, verify, and confirm the performance and cleanliness of EC/CF/TDS probes and conductivity-measuring instruments. It’s a ready-to-use calibration/checking solution that helps ensure your meters and probes are functioning correctly and giving accurate readings. The stable 2.77 EC value makes it ideal for testing after cleaning or maintenance of conductivity probes.

 Features & Benefits

✔ Reference Standard: Provides a trusted fixed conductivity point (2.77 EC) for verifying probe readings and confirming probe cleanliness.
✔ Improves Accuracy: Helps detect whether your EC probes are clean and responding correctly, which supports accurate nutrient monitoring.
✔ Ready to Use: No mixing is required — just pour and test.
✔ Stable Solution: Formulated and processed to provide a consistent, repeatable conductivity reference.
✔ Practical Size: 250 ml volume is suitable for multiple verification routines.

Typical Use

1. Clean your probe according to the manufacturer’s instructions to remove buildup.
2. Pour a small amount of the 2.77 EC solution into a clean container (don’t use the bottle itself repeatedly).
3. Immerse the probe and allow the reading to stabilize.
4. Check the reading — a properly functioning probe should show a value close to 2.77 EC.
5. Dispose of used solution from the small container after testing (do not return to the main bottle).
6. Rinse the probe thoroughly with clean water after the check.

 Storage & Handling

• Keep the bottle tightly sealed when not in use.
• Store in a cool, dark place to maintain solution stability.
• Avoid cross-contamination with other solutions or dirty instruments.
• Keep out of reach of children.
