Bluelab Replacement pH Probe for Guardian, Combo, & pH Meter
The Bluelab Replacement pH Probe for Guardian, Combo, & pH Meter is easy to clean because of its bullet shaped glass bulb. Fully waterproof and less fragile than all-glass electrodes because of its tough polypropylene barrel. Gel filled (non-refillable) making it maintenance free and a double junction reference providing longer life! All probes are interchangeable between all Bluelab products.

- All probes carry a 6 month warranty
- Proper hydration of pH probes is vital to maintain wick
- All pH probes eventually need to be replaced—they can only house so much reference solution
- KCl storage solution is required for optimum probe maintenance
- RO water will reduce probe life
