Blue Lab Meter

Post by Dan Green »

:surrender:
So thought I'd buy a blue lab meter - not cheap, but hey. Got a cheap one that reads ppm at say 1410 ish, blue says on the 500 scale about 2400 and 700 scale 3000+, what figure should I be looking at. Running my first rdwc which is fabulous

Dipping my toe into hydro, it's fabulous, and weird at the same time. Could do with a quieter pump too, anyway...

What is it calibrated to in the instructions? What model is it?

While on the subject I just read the Bluelab PH pens are going on 40-50% sale for black Friday.

Maybe someone can benefit 👊🏻

Combo is the model. Guess I'm asking what should the nutrient levels be in either the 500ppm or 700ppm scale...

The cheap meter you've got will be Hanna scale 500ppm. Not sure if that's the question.
EC of 2.4 would be 1200ppm on Hanna scale.

Drugs and Alcohol are never the answer! Unless the question was “what am I doing tonight”.
