ACI A/AN-DO-18" : Duct Temperature Sensor, 10K Type III Thermistor, 18" Probe Length, Flange Mount
ACI duct-mounted thermistors, crafted with rugged stainless steel probes and double-encapsulated for superior moisture resistance, deliver accurate air temperature readings in even the tightest spaces. High-quality thermal epoxy ensures fast response times, while the included insulation pad dampens vibration and seals your duct seamlessly. Choose the perfect sensor length to reach your duct's center (width or diameter) and monitor supply, discharge, return, and mixed air temperatures with ease. Ideal for roof-top units and air handlers, ACI Thermistor Duct Sensors are the key to optimal airflow control and system performance.
Key Features:
- Double encapsulation: ACI's unique double encapsulation process protects the sensor from moisture and ensures fast response times.
- 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.
