Product Information
Full details
The Extech AN100 is a thermo-anemometer designed for HVAC professionals and technicians who need to measure air velocity, air flow, and temperature in ventilation systems. Its key benefit is the simultaneous display of ambient temperature and air parameters on a large, backlit LCD, simplifying on-site analysis. A minor limitation is that the unit requires manual input of area dimensions for air volume calculations.

FAQs
What types of measurements can the Extech AN100 perform?
The Extech AN100 can measure air velocity, air flow (volume), and ambient air temperature.
How do I calculate air volume (CFM/CMM)?
After selecting the air flow mode, you need to enter the dimensions of the area (e.g., duct size) into the meter's memory. The device then uses these dimensions along with the measured air velocity to calculate air volume.
Does the AN100 measure surface temperature?
No, the AN100 measures ambient air temperature, not surface temperature. It is a thermo-anemometer, not an infrared thermometer.
What is the range for air velocity measurement?
The air velocity measurement range is typically from 0.40 to 30.00 m/s.
How long is the cable for the vane sensor?
The vane sensor comes with a cable that is 120cm (approximately 3.9ft) long.
What accessories are included with the AN100?
The device is supplied with a vane sensor, a 9V battery, a protective rubber holster, and a carrying case.
Can I store multiple area dimensions?
Yes, the AN100 can store up to 8 different area dimensions (in ft² or cm²) in its internal memory.
Troubleshooting
Device does not power on
Ensure the 9V battery is correctly installed and has sufficient charge. Check the battery contacts for corrosion.
Inaccurate readings
Verify that the vane sensor is clean and undamaged. Ensure the correct measurement mode and units (e.g., m/s, ft/min) are selected. Recalibrate if possible, or ensure area dimensions are correctly entered for air volume calculations.
Display is dim or unreadable
Activate the backlight by pressing the appropriate button. If the display remains dim, the battery may need replacement.
Error message on display
Refer to the product manual for specific error code meanings. Common solutions include checking sensor connections or replacing the battery.
Pros and Cons
Pros
- Simultaneous display of temperature and air measurements
- Calculates air volume (CFM/CMM) directly
- Large, backlit display for clear visibility
- Memory for storing area dimensions
- Includes essential accessories like a protective holster and carrying case
Cons
- Requires manual entry of area dimensions for air volume calculation
- Temperature measurement is ambient air, not surface temperature
- The text states it's machine translated, implying potential nuances in its original design or purpose.
Setup, Compatibility & Care
Setup:
- Install the 9V battery provided into the battery compartment.
- Connect the vane sensor cable to the appropriate port on the anemometer.
- Power on the device by pressing the power button.
- Select the desired measurement mode (Air Velocity, Air Flow, or Temperature).
- For Air Flow measurements, navigate to the memory function and enter the duct/area dimensions (ft² or cm²).
Compatibility:
The AN100 is designed for measuring air velocity, air flow, and ambient air temperature in HVAC systems, environmental monitoring, and general airflow applications. It is compatible with standard ventilation ducts and open spaces where air movement can be measured.
Care:
- Keep the vane sensor clean. Use a soft, dry cloth or a slightly damp cloth to wipe the sensor head if necessary. Avoid abrasive cleaners.
- Store the anemometer and its accessories in the provided carrying case when not in use to protect them from dust and damage.
- Avoid exposing the device to extreme temperatures or humidity outside its operating range.
- Remove the battery if the device will be stored for an extended period.
