2.77EC Conductivity Solution, 250 milliliters

Works great!

Keep it refrigerated after opening the container! It works great, but it degrade after use if not keep cold. I would also poor the product back into the container after testing. Poor it out and use fresh material from the bottle.

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.

Came sealed

Love the price

Awesome
