PH Probes

[GarrettT]

Using this probe to monitor my CaRx (alerting purposes). Anyone know if Neptune Apex's PH probe is any different than the ones listed below?

American Marine PINPOINT Lab pH Probe

PINPOINT pH Replacement Probe, Lab Grade, Double Junction: 10 foot cord, Ag-Ag/Cl reference, extended life, high supression cable jacket. Can be used on any standard BNC connection meter.

These are about 1/2 the price, so wanted to see if there was any difference. Curious to see what other peoples experiences were.

I've never used any non-Neptune Apex probe with my setup, but I guess for the price difference it's something worth a try.
