Used Neptune pH Probe
 

Hey there,

I have a 6 month old Neptune pH probe for sale out of Jericho Beach / Kits.

Neptune replaced this one as it arrived dry. Despite this, I got a good 6 months out of it without a glitch. The pH probe works reliably. I found it reads 0.1-0.2 pH units high (relative to my lab's probes) - but very stable and reliably notifies when there's a pH swing.

Make me an offer. It's sitting in RODI water at present. J & L sells for ~$100.

Cheers,
Ross

$20 takes it
