Application
Designed for duct temperature measurement in air handling units (AHUs), rooftop units (RTUs), VAV boxes, and fan coil units. Common applications include discharge air temperature monitoring, mixed air temperature sensing for economizer control, supply air verification, and freeze protection. The 18-inch probe length provides deep duct penetration for accurate average air temperature measurement in large ductwork. Ideal for integration with DDC systems, energy management platforms, and building automation systems requiring precise temperature feedback for HVAC control sequences and equipment protection.
Reliability & Performance
The 10K Type II thermistor provides excellent accuracy and repeatability across the full operating range with fast thermal response for precise control. Stainless steel probe construction ensures long-term durability in demanding HVAC environments with exposure to moisture, airborne contaminants, and temperature cycling. Flange-mount design simplifies installation and provides secure positioning in ductwork without air leakage. Industry-standard 10K thermistor output ensures broad compatibility with most DDC controllers and BAS platforms, reducing integration complexity and supporting reliable temperature control in critical HVAC applications.
