InTrac 776e Retractable Housing
For Refillable pH Sensors The InTrac 776e retractable housing is for applications in that utilize refillable-liquid electrolyte pH sensors. With a built-in flushing chamber, the electrode can be cleaned/recalibrated without interruption.
Easy Refill of Electrolyte
The InTrac 776e allows for easy retraction and electrolyte replacement and maintenance on refillable pH and ORP/redox electrodes.
Efficient Built-In Flushing Chamber
The electrode can be cleaned & recalibrated if necessary in the InTrac 776e built-in flushing chamber without any interruption of the ongoing process.
Ensure Safety & Reliability
For enhanced process safety, the InTrac 776e incorporates the Tri-Lock™ safety system to improve process reliability in harsh environments.
