New Neptune PH Probe

[blstravler]

does anyone know if new PH probes from Neptune need to be calibrated?

When I got a new probe from BRS it needed to be calibrated

I have one but it’s dried out and I’m not sure if it can de calibrated again once it’s dried out?

Calibrate it and compare to another test

Get some probe storage solution and soak the probe for a few hours. Then calibrate and it should be fine.

I'm guessing ALL pH probes need to be calibrated when you first purchase them. Neptune systems's probe required it and the new BRS probe I have does as well. Only ORP, as far as I know, doesn't need calibration.
