A retractable housing is a process connection for an analytical sensor that provides a secure way for a sensor to be removed from a process for calibration, cleaning or replacement, without interrupting the ongoing process. METTLER TOLEDO offers a variety of retractable sensor holders to suit specific applications and process environments. These retractable housings offer various operation mechanisms, materials and flushing chamber designs to optimize sensor maintenance.
The video introduces the retractable sensor housings series InTrac 7XXe for process measurements. These retractable sensor housings can be used in various industries and are designed for applications with highly demanding conditions.
Retractable housings make it easy to remove a sensor from the process for cleaning or maintenance. METTLER TOLEDO retractable housings offer both manual and pneumatic operation.
Retractable armatures allow you to withdraw a sensor from the process when a measurement is not needed. Retracting during harsh operations or cleaning processes extends sensor lifetime.
The unique dual-chamber housing of the InTrac797e/799e retractable housing allows a sensor to be cleaned in a completely sterile environment, reducing risks of cross-contamination into the process.
To ensure consistent and accurate measurements, retractable sensor holders can be integrated with EasyClean cleaning automation systems for easy sensor rinsing, flushing and cleaning.
Both sensor maintenance and calibration are possible at any time with no interruption to your ongoing process when using retractable housings, to help reduce costs and save time.
Retractable housings provide excellent installation flexibility at the measuring point with various construction materials, process connections and insertion lengths available for your process needs.
Retractable housings by METTLER TOLEDO are equipped with highly efficient cleaning chambers and a large bore size design to ensure that any unwanted dirt particles are flushed away properly.

A retractable housing is a process connection for an analytical sensor that provides a secure way for a sensor to be removed from a process for calibration, cleaning or replacement, without interrupting the ongoing process. METTLER TOLEDO offers a range of manual and pneumatic retractable armatures that are designed for operation in environments ranging from sterile and hygienic to dirty, industrial production. These retractable housing models are available to suit specific user requirements with diverse materials, process connections and insertion lengths. Retractable sensor holders can also be integrated with EasyClean cleaning automation systems for easy sensor rinsing, flushing and calibration.
METTLER TOLEDO offers a variety of retractable housing models to suit specific user requirements and process conditions. The InTrac 776e retractable housing is designed for applications in processes which utilize pH/ORP sensors that have a liquid electrolyte reference system.
InTrac 777e /779e retractable housings are specifically designed for applications in processes which utilize 12mm sensors for measuring pH, ORP, dissolved oxygen, CO2, conductivity and turbidity (InTrac 779e). These three models have a flushing chamber in which the electrode can be cleaned and calibrated if necessary, both accomplished without interruption of the process.
The InTrac 797e /799e retractable housing family is a sterilizable housing that has a double flushing chamber and is designed to meet the highest demands where sterile conditions are required.
InTrac 785/787 is a rugged, retractable housing for the most demanding industrial applications and includes an anti-blowout tip and ball valve for additional process safety.
The primary considerations when a sensor housing is selected are:
METTLER TOLEDO offers a series of EasyClean automated cleaning systems that can be integrated with retractable housing models to meet different user requirements. EasyClean 100 and EasyClean 150 take care of basic rinsing for minimally contaminated sensors. EasyClean 200e offers a solution for sensors subject to heavy fouling. EasyClean 400 is a completely automatic system for pH loops, rinsing, cleaning and calibration. And finally, EasyClean 400X is for hazardous areas that require special equipment.
