Bluelab Guardian Monitor Connect

I'm clearing out some gear and have this Bluelab Guardian Monitor Connect. It's a reliable 24/7 monitor for pH, conductivity, and temperature in your nutrient solution. It has the large backlit displays and is compatible with the Bluelab Connect Stick if you want to log data to a computer. Used, with some wear on the screen overlays as you can see, but it's a solid piece of equipment for any hydroponic setup.
