Suited for Long-Running Applications
The InTrac 797e is suitable for processes which run over an extended period due to the ability to maintain the sensor without disrupting the process.
Highly Efficient Double Flushing Chamber
The double flushing chamber allows complete sterilization of upper/lower parts of a sensor allowing the electrode to be changed in a safe environment.
Design to Prevent External Contamination
The twin-chamber lock design of the InTrac 797e retractable housing effectively prevents any external contamination while ensuring sterilization.
For enhanced process safety, the InTrac 797e includes a Tri-Lock™ system to improve process reliability in harsh pharmaceutical environments. The steel version is designed for safe operation in Ex-classified zones according to guideline ATEX 94/9/EC.
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.
The InTrac series offer a variety of different process adaptions, ranging from the tried and tested Ingold sockets, or flange fixtures, to special hygienic connection systems.
A wide variety of different types of electrodes and sensors can be used in conjunction with the InTrac family of retractable housings, whether in the measurement of pH/redox, dissolved oxygen, CO2, or conductivity.
