## Overview

BlueLab 2.77EC Conductivity Solution is a 250 ml reference liquid designed to calibrate and verify the accuracy of EC/ppm probes. With a precise conductivity of 2.77 mS/cm, it ensures your measurements remain reliable. The product is backed by a 100% manufacturer warranty and requires proper storage away from heat and sunlight to maintain effectiveness.

## Description

The EC2.77 solution is used as a reference or checking solution to ensure you have adequately cleaned the EC/ppm probe. Calibration Solutions should be stored in a cool place out of direct sun and heat. Please keep out of reach of children. They should be stored with the lids securely tightened.

Review: Works great!
Review: The bottle was exactly as expected, although I was unprepared to use it. The only cup I had at the time was from the cupboard and that use most of the solution just to test once. Since then, I’ve decided to order small paper "medicine" cups which will require far less solution. BTW after only having my pen for a couple months, it was pretty far off so I really needed the solution.

Blue lab is the manufacturer for most of my measurement instruments for my hydroponics. But I do have another brand that is part of my inline filtration and monitoring system, and this one did need to be recalibrated. Blue labs calibration solution was exactly what I needed and did the job.
