AD-1251 Probe with Differential Pressure Transducer
The airflow probe with high accuracy and reliability
Product overview
Our AD-1251 Airflow Probe includes a Differential Pressure Transducer (DPT) and is designed to provide accurate and energy efficient air flow monitoring at all times. Engineered specifically to measure air flow in duct applications, the AD-1251 functions as a differential pressure air measuring device that monitors air flow from 400 to 5,000 feet per minute (fpm). The AD-1251 is versatile and can be used in horizontal or vertical applications. When ordered with an air straightener, it is automatically positioned vertically.
Features
- The probe can be used in either a horizontal or vertical application
- Slip fit mounting provides easy installation
- Horizontal or vertical anodized aluminum sensing probes allow for measurement of lower air flows
- Factory-piped DPT with display provides visual readout of flow and reduces installation time
- Intended for retrofit projects
