These probes have straight and slim sensors with a fully enclosed or ungrounded probe that’s inserted into liquids, gels, and gases to measure temperatures. Also called immersion probes, these direct-connect probes are not made for fixed installations and are commonly used in industrial process applications and production environments.

These direct-connect thermocouple probes measure the temperatures of solid or semi-solid materials. Also known as insertion and penetration probes, they’re built with short or long straight sensors with a blunt, sharp, or reduced-diameter tip. The pointed tip is used to penetrate and measure the internal temperature of materials. They are commonly used to measure the temperature of molten plastics and rubbers and for recording temperatures in food production, storage, and transportation applications.

These thermocouple probes measure the temperature of air and gases. Also known as air probes, they’re built with the sensor tip exposed to air flow. The tip is housed in a perforated metal shield that protects it from the elements and ensures accuracy and fast response time. These direct-connect probes have a consistent diameter that makes them compatible with ducts, grilles, and vents.
