FA 4XX Wöhler fan anemometer

Description

The FA 4XX fan anemometer from Wöhler is a device for measuring air velocity, temperature and humidity at air vents.

It is also used for CO2 measurement at the vents (Wöhler FA 430 only), air leak detection, integrated volume flow measurement, direct volume flow measurement at the vents in combination with a cone and direct flow measurement at the air nozzle in combination with a funnel.

 

Main features

• Readings and data management in the Wöhler FA 4xx application
• easy handling
  • with automatic cone identification
• measurement report
  • via IR transmission to the Wöhler TD 100 Thermal Fast Printer
• Telescopic handle
  • e.g. for ceiling vents
• Optional units
  • m/s, fpm, m³/h, CFM, °C, °F, cm², in²
• LC backlit display
• HOLD-function
• MIN- / MAX-function

 

Use

Use the meter to measure air velocity, temperature and humidity (Wöhler FA 430 only) and CO2 concentration (Wöhler FA 430 only) and to calculate flow rate, dew point (Wöhler FA 430 only) and wet bulb temperature (Wöhler FA 430 only). Together with the cone, it is used to measure the air flow at the vents.

 

Different models

• Wöhler FA 430 (includes carbon dioxide measurements)
• Wöhler FA 410

Measuring the spatial flow at air diffusers

With the Wöhler FA 410 or FA 430 you can reliably determine the air velocity and temperature of air diffusers. In addition, the Wöhler FA 430 determines the CO2 content for air quality assessment.

 

Application

The measured values are displayed in the Wöhler FA 4xx app on the mobile device screen and can be saved in the app. You can also use your mobile device’s camera to take a photo of the object you want to measure. The photo shows the date and time of the recording and the readings at the time of recording. You can send the measurement data as an image or CSV file via an email or messaging service.
