Multifunction Airflow Test Instrument PCE-VA 20

The PCE-VA 20 is a versatile and portable airflow test instrument designed for assessing wind, weather, and environmental climate conditions, as well as evaluating heating, ventilation, air conditioning, and cooling (HVAC) systems. This multifunctional device measures airflow velocity, volume flow, relative humidity (RH), air temperature, dew point temperature, and wet-bulb temperature. Its compact design and robust feature set make it an essential tool for professionals working in environmental monitoring, HVAC testing, and industrial or laboratory applications.

Key Features:

• Comprehensive Measurement Capabilities: Measures air velocity, volume flow, relative humidity, air temperature, dew point, and wet-bulb temperature.
• High Accuracy and Resolution: Provides precise measurements with resolutions up to 0.1 for temperature and airflow.
• 10 cm / 3.9” Ø Fan Impeller: Ensures accurate airflow velocity measurements across a range of 0.2 to 30 m/s.
• Easy-to-Read Backlit LCD: Allows for clear data visualization, even in low-light environments.
• Convenient Functions: Includes display hold, average value, maximum value, minimum value, automatic power-off, low-battery indicator, and metric/imperial unit selection.
• Portable and Lightweight: Compact dimensions and a weight of approximately 200 g ensure ease of use and transport.
• Battery Operated: Powered by four AAA batteries for extended operation.
