Rigid Temperature Probe

Product Highlights
  • Everything great about the standard DTC.
  • Up to 6ft (1.8m) length
  • Armored or standard cable lead.
  • Unbelievably durable. Survives underneath pavements, near-shore sea ice, submersible.
  • Plug & Play with all beadedstream connectivity devices


Use the Rigid Temperature Probe for collecting temperature data with sensor spacing as close as every 2.5cm (1 inch). The Rigid Probes are stainless steel, solid, waterproof, and resistant to frost jacking forces that can overstress any cable solution. It is great for a variety of applications from road weather information systems (RWIS) to near-shore sea ice monitoring to pond and streambed temperature monitoring. The probe length is customizable to up to six feet (1.8m). A customizable lead length  can be added for precise installation in pavement sections if desired.


Resistant to frost jacking forces, ensuring durability and reliability under extreme conditions where other cable solutions may fail.

1-wire technology allows up to 72 sensors per probe with a minimum spacing of 2.5 cm, providing maximum resolution over depth.

Encased in rugged yet lightweight stainless steel, ensuring durability without compromising ease of use.

All-digital temperature conversion occurs at the sensor for better accuracy on your mission critical projects.

Stainless steel encasement with ruler decal representing ultra-fine sensor spacing, markings every 1-cm and 1-inch (2.5cm), for precision temperature gradients.
