ATP ET-935 Velocity & Volume Thermo-Anemometer

The ATP ET-935 Velocity & Volume Thermo-Anemometer combines air velocity, airflow volume and air temperature measurement in one portable instrument. Its 75 mm remote vane connects to the main unit through a 1.5 metre coiled cable, making it practical for measurements around ductwork, grilles, vents and ceiling diffusers. Air velocity can be displayed in m/sec, ft/min, mph, km/hr or knots to suit different working requirements.

For clear field readings, the instrument uses a 35 mm high-contrast LCD with a backlight and function indicators. A dual display allows velocity and temperature to be viewed at the same time, while a 16-segment bargraph gives a quick visual indication of changes in airflow. The ATP ET-935 Velocity & Volume Thermo-Anemometer also provides data hold, minimum and maximum recording, and a 10-second averaging function to help assess changing air conditions.

Built for regular ventilation, air conditioning, heating and environmental monitoring work, the meter covers air speeds from 0.4 to 30 m/sec and temperatures from -30°C to 60°C. Automatic power-off after 15 minutes of inactivity and a low-battery indicator help manage battery use during routine work. Supplied with a battery and soft carry case, the ATP ET-935 Velocity & Volume Thermo-Anemometer is ready for transport between survey and inspection tasks.

 

Key Benefits
  • Measures air velocity, airflow volume and temperature with one instrument.
  • Remote 75 mm vane helps reach ducts, vents, grilles and other confined test locations.
  • 1.5 metre coiled connection cable gives added flexibility when positioning the vane.
  • Dual display lets users view air velocity and temperature at the same time.
  • Backlit 35 mm LCD supports clear viewing in low-light working areas.
  • 16-segment bargraph provides a visual reference for changes in air velocity.
  • Data hold and minimum/maximum functions help capture changing airflow and temperature readings.
  • 10-second averaging helps stabilise displayed results when airflow is fluctuating.
  • Low-battery indication and automatic power-off support practical day-to-day use.

 

Common Applications

ATP ET-935 Velocity & Volume Thermo-Anemometer is suitable for a range of testing, maintenance and inspection tasks, including:

  • Ventilation surveys
  • HVAC system checks
  • Air conditioning applications
  • Heating applications
  • Environmental monitoring
  • Airflow checks in ductwork
  • Measurements at grilles and vents
  • Measurements at ceiling diffusers
  • HVAC airflow balancing tasks

 

Why Choose This Model?

At 292 g, the ET-935 is lighter than the AET-955 at 311 g and the AAVM-619 at 448 g, while its -30°C minimum temperature is lower than either alternative. Its maximum air velocity of 30 m/sec matches the AAVM-619, while the AET-955 extends to 45 m/sec.
