ACI A/100-2W-D-4"-PB : Duct Temperature Sensor, 100 Ohm Platinum RTD (Two Wires), 4" Duct Probe, Plastic Box Enclosure, Made in USA
The ACI Platinum Duct Series delivers precise temperature monitoring for your HVAC system with its high-quality stainless steel probe and color-coded Teflon wires for easy identification. Its proven double encapsulation process shields against moisture and ensures fast response times thanks to thermally conductive epoxy. Designed for smaller ducts, this single-point sensor features an insulation pad for airtight sealing and vibration dampening. Choose the ideal sensor length based on your duct size to get accurate readings from the center airflow. Optimize your HVAC performance and monitor critical temperatures in roof top units, air handlers, and supply/discharge/return/mixed air streams with the reliable ACI Platinum Duct Series.
