## Summary description

PTFE sinter cap designed for use with the Testo 0554 0756 probe. Made from chemically resistant PTFE material and suitable for high-temperature applications, it protects the sensor tip from aggressive media and contamination while allowing gas diffusion. Ideal for measurements in laboratories, industrial environments and chemical processes where corrosion resistance and thermal stability are required.

## Long description

The sinter cap PTFE for Testo 0554 0756 is a porous protection accessory made from chemically resistant polytetrafluoroethylene (PTFE) specifically shaped to fit the probe tip. It permits gas diffusion while shielding the sensor from aggressive media, particulate contamination and splashes in high-temperature environments. The cap maintains measurement integrity by offering a non-reactive barrier that withstands elevated temperatures and common corrosive substances encountered in laboratories, process lines and industrial applications.
Advantages
The PTFE construction provides broad chemical compatibility and a low surface energy that resists fouling and adhesion of residues, enabling stable readings over longer usage periods. Its sintered porous structure allows fast diffusion of gases to the sensor while preventing liquid ingress and particulate deposition. The material’s thermal stability supports measurements at higher temperatures without mechanical degradation, and the cap’s precise shape ensures a secure fit on the compatible probe for reliable protection.
Suitable for
 Gas measurements in chemical laboratories and research facilities
 Industrial process monitoring where corrosive vapours or splashes are present
 High-temperature sampling points requiring chemical resistance
 Environments with particulate contamination or aerosol exposure
Key specifications
 Material: chemically resistant PTFE (polytetrafluoroethylene)
 Design: sintered porous structure for gas diffusion and liquid repellence
 Temperature resistance: suitable for elevated temperature applications (material inherently heat-stable)
 Chemical resistance: compatible with a wide range of acids, bases and solvents typical in process and laboratory environments
 Function: protects sensor tip from contamination, splashes and particulates while allowing gas transport to the sensor
How to use
Fit the sinter cap onto the probe tip ensuring a snug, secure connection before taking measurements. Verify that the cap is clean and free of obstructions that could impede gas diffusion. Use the probe with the cap in place when sampling in environments with corrosive vapours, aerosols or high particulate loads. Periodically inspect the cap for buildup or damage and replace it if the porous structure is clogged or physically compromised to maintain measurement accuracy.
Usage recommendations
For reliable results, allow adequate equilibration time after placing the cap on the probe to account for the diffusion through the sintered material. Clean with compatible solvents and avoid abrasive cleaning methods. Replace the cap if exposure to strongly fouling media reduces response time or if any signs of mechanical wear appear.
