A replacement electrode for the MT608 & MT609 pH meter. The electrode is the consumable portion of the pH meter which actually makes the measurement. All pH electrodes wear out over time and must be replaced. If your meter is having trouble calibrating or the reading drifts then a bad electrode is the likely culprit.
This electrode was a perfect replacement for my Milwaukee 102. Only way to make it better is have them last 5 years instead of 1+ years, and make them less expensive!
This is the second time I have replaced the electrode. Simple and easy to remove the old one and attach the new one. These seem to last 1-2 years before needing replacement, depending on how heavy you use them. Nice to be able to replace the probe without having to buy an entirely new meter.
