Johnson Controls ST-D24 Duct Mount Thermistor 10K Ohm 8" Probe

The Johnson Controls ST-D24 is a duct-mounted thermistor temperature sensor designed for HVAC applications requiring accurate temperature monitoring in air handling systems. This sensor features an 8-inch stainless steel probe for durability and extended reach into ductwork.

Key Features:

• 10K Ohm thermistor element for precise temperature sensing
• 8-inch stainless steel probe construction resists corrosion and withstands harsh environments
• Wide operating temperature range from -40°F to 221°F (-40°C to 105°C)
• Duct mount configuration for installation in air ducts and plenums
• Compatible with Johnson Controls building automation and HVAC control systems

The ST-D24 thermistor provides reliable temperature feedback for zone control, energy management systems, and HVAC equipment monitoring. The extended probe length ensures accurate average temperature readings in the airstream, while the stainless steel construction ensures long-term reliability in commercial and industrial applications.
