Thermometer Pockets

Thermometer Pockets

Thermometer pockets are essential internal components for monitoring and controlling temperature inside chemical reactors, process vessels, and laboratory glassware. They provide safe, leak-free insertion of thermometers or temperature probes without compromising vessel integrity.

A thermometer pocket is a borosilicate glass or PTFE sleeve installed in the vessel wall or cover, designed to hold a thermometer, thermocouple, or temperature probe. It isolates the probe from the process fluid while ensuring accurate temperature measurement. Thermometer pockets are widely used in R&D, pilot, and industrial-scale reactors.

• Material: Borosilicate glass 3.3 or PTFE for chemical resistance
• Design: Straight, angled, or custom shapes
• Applications: Reaction monitoring, temperature-sensitive processing, batch control

Key Features & Benefits

Frequently Asked Questions (FAQ)

Q1: What materials are thermometer pockets made from?
A: Borosilicate glass 3.3 for chemical resistance, or PTFE for highly corrosive processes.

Q2: Can they be used under vacuum?
A: Yes, our thermometer pockets are designed for vacuum and mild pressure applications.

Q3: Are thermometer pockets customizable?
A: Absolutely! Length, diameter, and angle can be customized to your vessel design.

Q4: Can I use digital probes in these pockets?
A: Yes, they can accommodate digital, analog, or thermocouple probes.

Q5: How do thermometer pockets improve safety?
A: They isolate sensors from process fluids, preventing leaks, contamination, or chemical damage.

How Does It Work?

1. Installation: Inserted into the vessel wall or cover through a port or flange.
2. Insertion of Probe: Thermometer or thermocouple is placed inside the pocket.
3. Temperature Monitoring: Allows real-time measurement without direct contact with process fluid.
4. Process Control: Supports heating, cooling, or reaction monitoring efficiently.
