Measure the temperature of cylinders, pipes, and flat surfaces without installing an immersion probe and where a point sensor may be inaccurate. These RTD probes take multiple temperatures along the length of the probe and average them together for accuracy. About the thickness of a dime, they stick to surfaces in tight spaces.
