Bluelab Conductivity Standard Solution - 500ml - 2.77 EC

Lab-Grade 2.77 EC Reference for Probe Verification, 500ml

Cleaning a conductivity probe is only half the job; confirming the clean actually restored accurate readings is the other half. Bluelab Conductivity Standard Solution gives growers a known 2.77 EC reference point to check a probe against right after cleaning, catching a probe that still needs attention before it goes back into daily use.

This 500ml bottle holds enough solution for many verification checks, making it a practical size for a facility running several meters or probes on a routine cleaning schedule.

Key Features & Benefits

• Lab-grade 2.77 EC reference — a known value for verifying probe cleanliness and accuracy.
• 500ml bottle — sized for facilities running frequent checks across several meters or probes.
• Formulated for Bluelab devices — matches the accuracy expectations of Bluelab conductivity probes and pens.
• Supports a routine maintenance schedule — use after every cleaning to confirm a probe is ready to return to service.

Who Should Use This

Growers and technicians who clean conductivity probes on a regular schedule and want to confirm accuracy immediately afterward, particularly those running several meters across a larger facility, are the direct fit for this size.

Frequently Asked Questions

When should I use this standard solution?

Use it right after cleaning a conductivity probe to confirm the reading matches the known 2.77 EC value. If the probe reads significantly off, further cleaning or recalibration may be needed before returning it to service.

Is this a calibration solution or a verification solution?

This is a standard/reference solution used mainly to verify cleanliness and accuracy after cleaning, though it uses the same 2.77 EC value referenced in calibration routines. Check your specific meter's documentation for its calibration procedure.

How should I store this solution?

Store it in a cool place out of direct sunlight and heat, with the lid tightened securely between uses. Keep it out of reach of children.

Why choose the 500ml size over the smaller bottles?

The 500ml bottle reduces how often you need to reorder if you are checking multiple probes or meters on a frequent schedule. Smaller 120ml and 250ml sizes suit lighter, occasional use.
