Incorporates a flushing mechanism into the reference junction assembly of a standard epoxy or glass body pH electrode. This flushing mechanism is activated by pushing the spring loaded cap in glass body models, or lifting the cap on epoxy body models. This feature gives fast, accurate, and incredibly stable pH readings, as well as excellent temperature response. Spring tension on the epoxy version may be adjusted to control flow rate. Both epoxy body and glass body versions incorporate a double junction reference. 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 flow rates for stability and accuracy. Temperature range 0 to 60°C (epoxy), 0 to 100°C (glass). Response time 3 seconds to 98% of final value. BNCconnector.
