Harco designs and manufactures total air temperature sensors that enable computation of static air temperature and true airspeed. The sensors are currently used on military aircrafts. The company also produces three versions of outside air temperature sensors, which can be a cost effective replacement for total air temperature sensors; and resistance temperature sensors, which are used in the most exacting applications such as harsh turbine engine environments.

Dwyer manufactures a variety of temperature sensors including: air/duct temperature sensors; averaging temperature sensors; general-purpose, immersion temperature sensors; weatherproof, immersion temperature sensors; in-line IR sensors; outside air temperature sensors; surface-mount temperature sensors; wireless, remote-probe temperature sensors; and wireless, wall-mount temperature sensors.
