HTC AVM-07 Anemometer

Q1: What parameters can the AVM-07 measure?

The AVM-07 is a multi-function anemometer that measures Air Velocity, Air Flow (volume), Beaufort Scale, Wave Height, Air Volume in CFM/CMM, and Ambient Temperature. This makes it suitable for HVAC, marine, environmental, and industrial applications.

Q2: What is the difference between Air Velocity and Air Flow?

Air Velocity measures the speed of air movement (e.g., m/s, km/h, mph). Air Flow (or Air Volume) calculates the total volume of air moving through a duct or opening per unit of time (CMM or CFM). The AVM-07 can compute air flow when you input the duct cross-sectional area.

Q3: How does the detachable vane probe help?

The external vane probe connects to the main unit via a cable, allowing you to insert the sensor into ventilation ducts, exhaust ports, or elevated areas while holding the display unit at a comfortable viewing position. This improves safety and convenience in tight or high spaces.

Q4: What velocity units are available?

You can switch between meters per second (m/s), kilometers per hour (km/h), feet per minute (ft/min), knots, and miles per hour (mph) using the UNIT button. This flexibility ensures compatibility with international standards and client reporting requirements.

Q5: How do I use the Beaufort Scale and Wave Height modes?

These modes are designed for marine and coastal use. The Beaufort Scale converts wind speed into the standardized wind force scale (0 to 12), while Wave Height mode estimates probable wave heights based on measured wind conditions. Select these via the FUNCTION button.

Q6: What is the Max Data Hold function?

Max Data Hold captures and freezes the highest reading detected during a measurement session. This is especially useful for recording peak gusts, maximum exhaust velocity, or surge conditions in ventilation systems without constantly monitoring the display.

Q7: How does the 24-group memory work?

The AVM-07 can store up to 24 sets of measurement data internally. Press the SAVE button to record a reading, and use the READ button to scroll through and recall stored values later. This eliminates the need for manual note-taking during surveys.

Q8: Can I transfer data to a computer?

Yes. The AVM-07 is equipped with a USB interface. Connect the device to your PC using the provided USB cable to download stored measurement data for analysis, reporting, and record-keeping in spreadsheet or document format.

Q9: Is the display readable in dark environments?

Yes. The AVM-07 features a large LCD with a blue backlight that illuminates the screen, making it easy to read measurements in dark basements, engine rooms, outdoor nighttime conditions, and poorly lit industrial facilities.

Q10: What type of batteries does the AVM-07 use?

The AVM-07 is battery-operated. Please refer to the user manual included in the package for the exact battery type and quantity required (typically a 9V block battery or AA cells). The auto power-off feature helps extend battery life during field use.
