good question, i have a milwalkee that is not see-thru like my lab grade probe, i think i will crack it open and see if i can refill it and re-seal it. it is due to be replaced, instead i will make it a sacrificial lamb. i wouldnt trust it as your main source of ph determination if it is messed with like that.RichT said:Can the regular Pinpoint or Neptune probes be opened and refilled?
RichT said:So tomorrow night I will try it out. I still have the cal solution sitting in shot glasses so it will be a quick check. If I still get nothing, I'll let it go the week and give it one more shot.
