The Signet 3719 pH/ORP Wet-Tap allows installation and removal of pH or
ORP electrodes without the need for process shutdown during routine electrode
maintenance and calibration. Process isolation is achieved with a double O-ring
seal on a unique and compact retraction assembly; no separate valve is required.
A cam-activated automatic locking mechanism, SafeLoc™, and the short stroke
design help to assure operator safety.
