Why choose it

The M4 threaded probe allows easy mounting into threaded holes or thermowells, ensuring secure thermal contact. The stainless steel housing resists corrosion and mechanical stress, while the PVC cable remains flexible even at low temperatures. The open cable ends give you the freedom to connect to screw terminals, plugs, or solder joints, making integration straightforward.

Ideal use cases

• Temperature sensing in 3D printers, extruders, or heated beds
• Monitoring motors, bearings, or power supplies
• HVAC duct or pipe surface temperature measurement
• Laboratory equipment and test rigs
• Custom electronics projects with microcontrollers

Good to know

The sensor is not waterproof beyond the probe tip; protect the cable and connection points from moisture. For best accuracy, ensure the probe is fully inserted into the medium being measured. The 3435K beta value is a common standard, but verify compatibility with your controller's settings.
