ORP PROBE
Replace your ORP probe or add another for another tank
Buy this probe if you are:
- Replacing a worn out ORP probe
- Adding another tank to your system and purchased a PM1 to do so.
- Double Junction probes will last longer- about twice a long. A Single Junction Lab grade should be replaced in 12 months and a Double Junction Lab Grade should be replaced in 24 months.
