Omega HHF143 anemometer calibration

In aviation, anemometers are commonly used to detect changes in air speed. The Omega HHF143 anemometer is a popular option for many MROs and FBOs. This instrument is chosen due to a high accuracy of ±1% and sensitivity to low wind speeds. To make sure that speed and temperature measurements are reliable, regular Omega HHF143 anemometer calibration and maintenance are required.

How Does the Omega HHF143 Anemometer Work?

The Omega HHF143 can be referred to as a propeller, windmill, rotating vane, or vane thermo-anemometer. In this type of anemometer, wind causes the instrument blades to revolve on a rod. The motion causes the rod of the anemometer to rotate horizontally. The instrument uses this data to calculate wind speed. The speed is then shown on the digital display.

Accuracy & Range

The air velocity data is ±1.0% of the reading ±1 digit. Temperature accuracy is ±0.3°C + 0.2% of the reading. The instrument operating temperature is 0° – 50°C (32° – 125°F). The temperature range is -20° to 100°C (-4° to 212°F). Data is displayed to 4 digits.

Omega HHF143 Anemometer Calibration

All Omega HHF143 anemometers that are purchased through the OEM are received in calibration (traceable to NIST). The manufacturer recommends yearly Omega HHF143 anemometer calibration testing. Most quality or tooling managers will schedule calibration after first use. Some organizations may require a six month Omega HHF143 anemometer calibration interval depending on quality system requirements.
