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.

Reduce Overall Process Costs
The InTrac family of retractable housings helps to substantially reduce the operating costs of a measuring point, by allowing well-planned automatic cleaning and calibration of a sensor, which will increase its average operational life significantly.
Highly Versatile Product Configurations
Immersion depths are variable with the InTrac 776e retractable housing, and can be suited to the design and configuration of vessels and pipes. Available immersion lengths are 70mm and 100mm for 250mm sensors, and 200mm immersion for 450mm sensor lengths.
Materials to Meet Your Environment
Multiple process connections and materials make the InTrac 776e a great choice by offering 316 L stainless steel, Hastelloy – C22, titanium, PP, PVDF, and PEEK versions for applications in chemical, biopharmaceutical or food and beverage industries.
