The simplest & most effective reservoir monitor you could ever own!

Provides 24 hour continuous reading for pH, conductivity (EC/PPM) and temperature within a nutrient solution. Designed for indoor use, this can be mounted on a wall or hung on a support bar. Set up your reservoir, place the pH and conductivity probes in the solution, then adjust and glance! Simply set high and low alarm states - if the solution moves away from the ideal range, the display flashes. A quick look at the monitor will let you know when your nutrient solution needs adjusting. Also available in connect with data logging features.
Includes 2 year warranty on the monitor, 6 month on the probe.
