"pHastrode"

Special pH Electrodes for Paints and Inks With Flushing Mechanism

pHastrode

This unique "pHastrode" pH electrode design incorporates a flushing mechanism into the reference junction assembly of a standard epoxy or glass body pH electrode. The flushing mechanism is activated by pushing the spring loaded cap. This feature, when coupled with our advanced pH measuring membrane and unique internal fill solution, gives fast, accurate, and incredibly stable pH readings, as well as excellent temperature response.

"pHastrode" electrodes, by nature of their design, have a faster flow rate past the reference junction than most combination electrodes. A faster flow rate enables the electrodes to work particularly well in slurry applications where clogging is prevalent, as well as low conductivity solutions which require faster junction flow rate for stability and accuracy. Additionally, several pH measuring membranes are offered enabling each user to customize the electrode for their application.

Type 2 glass - 0 to 12 pH. (low impedance for high purity water applications)
Type 3 glass - 1 to 12 pH. ("hard bulb" for viscous materials, slurries)
Type 7 glass - 0 to 14 pH. (dome or ruggedized bulb)
Lead Wire: 3 foot standard, up to 10 foot available
Connector Type: BNC standard with many others available.

 

Applications

top
Measuring viscous, oily, dirty, non-aqueous or sulfide containing samples quickly ruins most pH electrodes. The "pHastrode" solves this problem with a unique, flushable, reference junction. When the sample blocks or fouls the reference junction, a quick press of the "pHastrode" cap opens the junction, flushing clean the reference element and restoring like new electrode performance.

 

Design

top
Epoxy and glass bodied versions are available. The epoxy body version may be completely disassembled for cleaning purposes. The glass bodied version offers not only the same convenient feature as the epoxy bodied version, but also offers high chemical resistance of an all glass design. Both epoxy body and glass body versions incorporate a double junction reference and may use any pH measuring membrane necessary to meet measurement needs.
