pHASE
electrodes, unlike standard electrodes, provide fast, accurate
and stable pH measurements, even with large sample temperature
changes. The ideal choice for quality control and R&D
use. All pHASE electrodes are combination types with built-in
double junction references. This feature prevents the silver
ions in the electrode from contacting product samples. Undesirable
reactions with heavy metals, sulfides and proteins are prevented.
pHASE electrodes are available with Sealed or Rapid-Renew
built in reference half-cell designs.

Economical
Sealed Designs
Sealed
designs are the most economical, easiest to use and they minimize
maintenance. They are useful in a broad range of applications.
Rapid-Renew
Refillable Electrodes
Rapid-Renew
designs are refillable. They are most useful with dirty or other
samples that cause junction fouling. Simply pushing a spring loaded
top cap, (just like clicking a pen) opens the sleeve junction
to instantly provide a fresh junction. To simplify filling, we
have designed a twist-seal re-fill valve. Like a miniature ball-valve,
a quarter turn opens (or closes) the hole's leak tight "O"
ring seal. The need for awkward sleeves and threaded plugs is
eliminated.
Body Material Choices
pHASE
electrodes are available with either plastic or glass 12mm body
construction. Plastic designs have excellent chemical resistance
and feature a re-movable bulb guard. Glass designs have maximum
chemical resistance and feature exposed ruggedized bulbs.
