InTrac 779e Retractable Housing
Simplifies Sensor Maintenance The InTrac 779e retractable housing is designed for industrial processes that use 12mm turbidity sensors. With a built-in flushing chamber, the electrode can be cleaned/recalibrated without interruption.
Easy Access to In-Line Sensors
The InTrac 779e offers manual or pneumatic sensor withdrawal for easy maintenance or replacement of turbidity sensors.
Highly Efficient Flushing Chamber
To ensure particles/dirt are flushed away, the InTrac 779e has a single flushing chamber to clean and calibrate the electrode with no interruptions.
Prevents Process Leaks
The safety system prevents any release of process media from the housing. Without a sensor in place, the housing cannot be inserted into the process.

Ensure Process Safety & Reliability
For enhanced process safety, the InTrac 779e includes a Tri-Lock™ system to improve process reliability in harsh environments. The steel version is designed for safe operation in Ex-classified zones according to guideline ATEX 94/9/EC.
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.
Materials to Meet Your Environment
Multiple process connections and materials make the InTrac 779e 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.
