HT625A Handheld Digital Industrial Anemometer with 8 Fan Blades and Bearing Sensor
The HT625A Handheld Digital Industrial Anemometer is a professional-grade yet portable instrument designed to accurately measure air speed, air volume, and airflow dynamics in a wide variety of industrial, commercial, and environmental applications.
Unlike basic pocket anemometers, the HT625A combines precision engineering with a high-sensitivity bearing sensor and 8-blade fan, ensuring smooth operation, reliable readings, and greater durability. Its ergonomic handheld design makes it suitable for HVAC testing, environmental monitoring, laboratory use, and fieldwork where quick and accurate airflow measurement is essential.

Key Functions
- Air Speed Measurement – Detects wind speed across multiple units (m/s, km/h, ft/min, mph, knots), with high accuracy for industrial testing or outdoor monitoring.
Air Volume Calculation – Allows airflow measurement in CFM (Cubic Feet per Minute) or CMM (Cubic Meters per Minute), especially useful for HVAC systems and duct efficiency checks.
Air Duct Area Setting – Input the duct dimensions to calculate airflow more precisely in ventilation systems.
MAX/MIN & AVG Modes – Capture maximum, minimum, and average readings to evaluate fluctuations in airflow or wind patterns.
