InTrac 777e Retractable Housing

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.
