InTrac 781 (Single Flushing Chamber, Chemical Applications)
Sensor Housings for Harsh Conditions.
InTrac 781 retractable housings are specially designed for use in a wide range of harsh industrial processes. Wetted parts are available in different materials, offering installation flexibility in many applications. The intelligent sensor locking system prevents deployment of the insertion rod if no sensor is present. InTrac housings can be operated with EasyClean systems for automatic sensor cleaning, flushing and calibration. With the housings' specially designed cleaning chamber, sensors can be thoroughly and quickly cleaned whenever required.
