E+H iTHERM SurfaceLine TM611 Surface thermometer
$600.00
Non‑invasive RTD/TC surface thermometer suitable for demanding industrial temperature measurement — accurate, safe and easy to install without process penetration. Typical Applications:
• Process temperature monitoring where invasive thermometers are difficult or costly to install
• Retrofitting temperature measurement on existing pipework
• Energy, heat exchanger and safety monitoring across industries
• Applications with corrosive, abrasive or high‑velocity fluids where leakage risk must be minimized
Not Recommended For:
• Simple temperature measurement where invasive thermometers are already suitable
• Applications without need for non‑invasive mounting
Selection Notes
• Confirm if a non‑invasive surface thermometer is preferable to an invasive thermowell solution
• Evaluate pipe material and insulation requirements for optimal thermal coupling
• Understand that advanced thermal coupling element ensures high accuracy similar to invasive devices
• Ideal for standard and demanding industrial environments with external pipe surface mounting
Why Choose iTHERM SurfaceLine TM611
• Accurate and fast temperature measurement without process penetration
• Eliminates leakage risk and flow disruption from thermowell installations
• Cost and time savings in engineering, installation and certification
• Easy subsequent installation on existing pipes with minimal plant downtime
• Compatible with standard iTEMP temperature transmitters and communication protocols
• Suitable across heavy industries including chemical, energy, hydrogen, HVAC and utilities
FAQ
Q: How does a non‑invasive thermometer compare to an invasive sensor?
