InTrac 777e Retractable Housing

Simplifies Sensor Maintenance The InTrac 777e retractable housing is designed for industrial processes that use 12mm gel-filled electrodes for the measurement of pH/ORP, DO, CO2 & conductivity. With a built-in flushing chamber, the electrode can be cleaned without interruption

Easy Access to In-Line Sensors

The InTrac 777e offers manual or pneumatic sensor withdrawal for easy maintenance or replacement of pH, DO, CO2 or conductivity sensors.

Highly Efficient Flushing Chamber

To ensure particles/dirt are flushed away, the InTrac 777e 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 777e 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 777e 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.
