Ruskin® model TDP05K is a highly accurate thermal dispersion airflow and temperature measuring probe. Multiple velocity and temperature points on one or more probes installed in the duct or plenum are averaged to arrive at air measurements. The TDP05K is capable of measuring a velocity range from 0 to 5,000 FPM and displaying the flow and temperature at each sensing point. Within each low pressure drop airfoil shaped probe are up to 8 moisture resistant flex sensors. The highest accuracy over the entire range of air flows results from probe sensing elements that are factory tested and calibrated at 20 points.
