ACI A/AN-D-4"-GD : Duct Temperature Sensor, 10K Type III Thermistor, 4" Probe Length, Galvanized Steel Enclosure
The ACI Thermistor Duct Series is a line of high-quality temperature sensors designed for precise air temperature measurement in HVAC applications. Featuring a durable stainless steel probe and two color-coded lead wires for easy identification, these thermistors are built to withstand demanding environments.
Key Features:
- Double encapsulation: ACI's unique double encapsulation process protects the sensor from moisture and ensures fast response times.
- Compact design: Ideal for smaller duct applications, the duct sensor includes an insulation pad for optimal sealing and vibration dampening.
- Accurate and reliable: These thermistors offer exceptional accuracy (±0.2°C) and a quick response time (10 seconds).
- Wide range of applications: Suitable for monitoring air temperatures in roof top units, air handlers, and supply,discharge, return, and mixed air ducts.
