The low maintenance sealed designs are economical and easy to use. Their porous polyethylene junction resists clogging and provides good chemical compatibility with many solutions. The refillable ALpHA® Series electrodes have a unique spring-loaded knob that opens the sleeve junction to provide fresh reference fluid. The refillable style also has a twist-seal refill hole that opens by simply turning the collar, making the refilling process less awkward. ALpHA® Series pH electrodes are available in epoxy body and glass body styles. The epoxy model is used for applications that require a more rugged electrode the glass style offers a better range of chemical compatibility. All ALpHA® Series electrodes can measure the full 0-14 pH scale (0-12 pH without sodium ion error) and can withstand temperatures from 0 to 100°C (32 to 212°F).
Application Suggestions
PHE-4810 Sealed with an epoxy body and removable bulb guard. Suitable for general laboratory applications that require a double junction style.
PHE-4815 Sealed with a glass body. Suggested for applications similar to the PHE-4810, but with broader chemical compatibility.
PHE-4821 Refillable electrode with epoxy body and removable bulb guard. Suitable for samples that can cause junction fouling. Also features Rapid Renewal Junction.
PHE-4830 Sealed, with a flat measuring surface. Suitable for measuring semi-solids, slurries, and viscous materials.
PHE-4841 Refillable with a glass body. Suggested for similar applications suited to the PHE-4821, but provides better chemical compatibility. Rapid Renewal Junction feature.
