Product Information
Full details
The Extech AN300 Anemometer is designed for HVAC professionals, engineers, and researchers who need precise airflow and temperature measurements in larger ducts. Its key benefit is the simultaneous display of air velocity/flow and temperature using a large 10cm vane, allowing for more accurate readings in demanding environments. A potential caveat is its specialized nature, primarily suited for applications involving larger ducts.

FAQs
What is the primary application for the Extech AN300?
The Extech AN300 is ideal for measuring air velocity and temperature in larger ducts, making it suitable for HVAC, industrial, and research applications.
Can the AN300 measure airflow in CFM?
Yes, the AN300 can measure airflow in units such as CFM (Cubic Feet per Minute) and m³/min, in addition to air velocity.
How do I clean the vane sensor?
Gently wipe the vane sensor with a soft, slightly damp cloth. Ensure it spins freely afterward. Avoid using harsh chemicals.
What do the Min/Max and Average functions do?
These functions allow you to track the minimum, maximum, and average readings over a period, providing valuable data for performance analysis.
Does the AN300 have an auto power-off feature?
Yes, the AN300 includes an auto power-off feature to conserve battery life when the device is not in use.
Can this anemometer be used for small residential ducts?
While it can be used, the 10cm vane is optimized for larger ducts. For very small ducts, a smaller vane anemometer might provide more convenient measurements.
What is the purpose of the built-in ratiometer?
The built-in ratiometer is used for split-field measurements, which can help in comparative airflow analysis within a single system or duct.
Troubleshooting
Device does not power on
Check if the battery is installed correctly and has sufficient charge. Replace the battery if low.
Inaccurate or unstable readings
Ensure the vane is clean and can spin freely. Check for obstructions. Verify correct measurement units and duct area input. Avoid sources of interference like strong magnetic fields.
Display shows error code
Refer to the user manual for specific error code meanings and troubleshooting steps. Power cycle the device and try again.
Temperature reading is incorrect
Ensure the temperature sensor on the vane is not obstructed or damaged. Allow the device to acclimate to ambient temperature before taking readings.
Pros and Cons
Pros
- Accurate readings on large ducts due to the 10cm vane.
- Simultaneous display of airflow and temperature saves time.
- Advanced calculation features (Min/Max, Average) support detailed analysis.
- Durable design suitable for field use.
- User-friendly interface with clear dual LCD display.
Cons
- May be oversized for very small duct applications.
- Requires proper technique for optimal split-field measurements.
- Not designed for non-airflow related measurements.
- Battery life can be affected by frequent use of advanced functions.
Setup, Compatibility & Care
Setup:
- Ensure the anemometer is powered on using the appropriate button.
- Select the desired measurement units for air velocity (e.g., m/s, ft/min, knots) and airflow (e.g., m³/min, CFM).
- For airflow measurements, input the duct area (if not using the ratiometer for split-field).
- Position the 10cm vane sensor directly into the airflow stream.
Compatibility:
The AN300 is primarily designed for measuring air velocity and temperature in HVAC systems, industrial applications, and research environments. It is compatible with duct sizes where a 10cm vane can be effectively inserted for readings.
Care:
- Cleaning: Gently clean the vane and housing with a soft, dry or slightly damp cloth. Avoid harsh chemicals or abrasive cleaners. Ensure the vane spins freely after cleaning.
- Storage: Store the anemometer in a cool, dry place away from direct sunlight and extreme temperatures. Use the protective cap when not in use.
- Calibration: While specific calibration instructions are not provided, regular checks against known airflow sources are recommended for critical applications. Consult Extech for professional calibration services if needed.
