PurGro GroBot pH Probe, Industrial Replacement meters-&-solutions during winter monthsThese don't look like the ones from the hydro store because they are double junction, flat surface pH probes typically used in chemical plants for process control. They last longer, stay cleaner and are built to mount in line inside your GroBot Evolution. Cost a few bucks more, but these are the good ones. Proudly made in the USA.
