This easy to use Anemometer measures Airflow, this airflow measurement can be displayed in 5 different measurement units: metres per second, feet per minute, knots, mph and kph. The Martindale AV90 Anemometer / Airflow meter also displays temperature (either Celsius or Fahrenheit) using the provided external probe. This test meter displays temperature and air flow at the same time! Maximum and minimum figures can be also be shown for air speed and temperature.

For higher accuracy, this Anemometer / airflow test meter also takes up to 8 readings which are automatically averaged. Futhermore the Martindale AV90 Anemometer tester can take measurements over either 2 or 16 seconds and the average of the 2 to 16 readings is displayed on the clear digital LCD. The Martindale AV90 Anemometer is ideal for testing and measuring airflow ventilation systems, heating systems, refrigeration units, sewage systems and air conditioning systems. This Anemometer / Airflow meter with temperature display provides quick and easy results when measuring temperature and airflow for commercial, industrial, residential purposes as well as offices factories, hotels and shops.
