Bluelab Conductivity Standard Solution - 120ml - 2.77 EC

Lab-Grade 2.77 EC Reference for Probe Verification, 120ml

A quick verification check after cleaning a conductivity probe does not always call for a large bottle of reference solution, and the 120ml size of Bluelab Conductivity Standard Solution covers exactly that lighter, occasional use case. It gives the same known 2.77 EC reference value as the larger bottles, just in a smaller, easy-to-store size.

Use it right after cleaning a probe to confirm the reading matches the known reference before returning the probe to service.

Key Features & Benefits

• 2.77 EC reference value — a fixed conductivity benchmark for spot-checking probe accuracy.
• 120ml bottle — a compact size suited to a single meter or occasional checks.
• Matched to Bluelab conductivity hardware — built to the tolerances Bluelab conductivity probes and pens expect.
• Easy to store — small enough to keep alongside a single meter's maintenance kit.

Who Should Use This

Growers with a single conductivity meter or pen who check probe accuracy occasionally, rather than on a heavy multi-meter schedule, are the direct fit for this smaller size.

Frequently Asked Questions

What is the right time to check a probe with this solution?

Dip the probe right after cleaning and compare the display against the 2.77 EC benchmark. A reading that is noticeably off suggests the probe needs another cleaning pass or a recalibration before it goes back into service.

Is the 120ml size enough for regular use?

This size suits occasional checks on a single meter well. Growers verifying several meters on a frequent schedule may prefer the larger 250ml or 500ml bottles instead.

How should I store this solution?

Keep the bottle sealed and tucked away from direct sunlight or heat between uses. This small size stores easily in a drawer or cabinet out of reach of children.

Can this solution be used with non-Bluelab meters?

It is manufactured to general laboratory standards, but is matched specifically to Bluelab conductivity hardware. Bluelab recommends pairing it with its own devices for guaranteed compatibility.
