SOLD
Used for about three years, this unit reliably measures pH. When I have periodically attempted to calibrate it, it was always spot on, not needing an adjustment. I'll enclose some packets of pH calibration solution too.
Of course, we don't depend on these to control our pH any more, but they can still act as a "fail safe".
Just so you know, I upgraded to an Aquacontroller Jr some years ago and the Pinpoint has been in storage since.
Reviews and pricing if new here.
Plastic guard on probe is chiped, but the glass is OK. The probe has been stored in buffer and never has gone dry. New probes are here.
Comes with instructions.
$70 OBO (considered) not including shipping.
Please PM me.
Thank you...
