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.
