Description
Product Overview
The Extech AN100 CFM/CMM Thermo-Anemometer is a compact, handheld instrument designed for precise measurement of airflow and temperature in a variety of professional environments. Constructed from durable plastic housing, the device measures 2.9 x 1.3 x 7 inches and weighs just 0.73 kilograms, making it easy to carry and operate with one hand. Its large LCD screen simultaneously displays airflow in cubic feet per minute (CFM) or cubic meters per minute (CMM) alongside ambient temperature, allowing users to capture critical data without switching modes.
Equipped with a low‑friction 2.83‑inch (72 mm) ball‑bearing vane wheel, the AN100 achieves a velocity accuracy of ±0.5 % across its measurement range. The instrument also features a 20‑point averaging function that smooths transient fluctuations, delivering stable and reliable readings even in turbulent air streams. An internal memory stores up to ten custom area dimensions (in cm²), which are automatically recalled each time the device is powered on, streamlining repetitive testing procedures.
Usage
Designed for HVAC technicians, laboratory researchers, and industrial maintenance personnel, the AN100 excels in environments where accurate airflow and temperature data are essential. Use it to verify ductwork performance, calibrate ventilation systems, assess cleanroom conditions, or monitor airflow in manufacturing processes. Its battery‑powered operation (one AA alkaline battery, included) ensures uninterrupted use in field settings, while the ergonomic design reduces user fatigue during extended measurement sessions.
Because the device records both airflow and temperature, it is particularly valuable for energy‑efficiency audits, where correlating temperature gradients with air movement helps identify heat loss or gain. The built‑in memory of area dimensions simplifies calculations for square‑footage ventilation requirements, making the AN100 a versatile tool for both routine maintenance and detailed engineering analysis.

FAQ
What type of battery does the AN100 require?
The AN100 operates on a single AA alkaline battery, which is included in the package. The battery provides several hours of continuous use, and the device alerts you when the power level is low.
Can the AN100 measure both CFM and CMM simultaneously?
Yes, the instrument can display airflow in either cubic feet per minute (CFM) or cubic meters per minute (CMM). You select the desired unit via the mode button, and the LCD updates instantly.
Is the device suitable for outdoor measurements?
While the AN100 is built with a durable plastic housing, it is intended for indoor use where dust and moisture levels are controlled. For outdoor applications, additional protective measures are recommended.
How does the internal memory function?
You can program up to ten custom area dimensions (in cm²) directly into the meter. These values are saved in non‑volatile memory, so they remain available after the device is turned off and on again, eliminating the need to re‑enter data for recurring tests.
What is the warranty coverage?
Extech provides a one‑year limited warranty that covers defects in materials and workmanship. Should any issue arise, you can contact Extech support for troubleshooting, repair, or replacement options.
