Replacement PH Probe
I have an American Marine Pinpoint pH Monitor which requires a replacement PH probe.
Instead of spending $50 for a new replacement for a LFS, has anyone ever purchased replacement PH probes from eBay? Similar to this one which sells $8USD? http://www.ebay.com/itm/PH-Electrode...item540149d8dd What's your opinion? |

I never tried one but that's a heck of a deal if they are accurate.
