Hi All,
I upgraded to a 2016 APEX when I switched tanks recently, and am selling my old base unit with probes. Temp and pH probes are older, but ORP probe is brand new out of the 2016 APEX box. Works great, temp probe was within .2 degrees of a temp probe and pH probe was still accurate when pulled. Both pH and ORP probes stored in RODI water.
$200 shipped including paypal fees.
