The Anemomaster™ Rotating Vane 6810 Series of anemometers offers a range of highly accurate airflow measuring devices. Models include industrial grade enclosure and probe. They automatically calculate volume flow in CFM (cubic feet per minute) or CMH (cubic meters per hour). When measuring ducts dimensions are stored in memory on turn-off and do not need to be re-entered. These vane anemomters can store up to 10 different commonly-used duct sizes for quick, convenient readings in the field. Models also available for airflow/temperature and airflow/termperature/humidity.

Does the unit come with an NIST traceable certificate?

Yes, all our instruments come with a calibration certificate.

How often does the unit need to be calibrated?

Kanomax recommends annual calibration to ensure accuracy.

Can I measure airflow in flammable and corrosive gases?

No, these are thermal anemometers that generate heat when in operation; if you expose them to a flammable gas it could cause a fire or explosion. Corrosive or caustic gases, such a chlorine, will damage the sensor on contact. While it is possible to use the instrument in a non-flammable, non-caustic gases the instrument is not calibrated for these gases and it will not measure airflow accurately.

Do you need to buy a separate probe for measuring velocity and temperature on the model 6824 Vane Anemometer?

No, the temperature sensor is built into the velocity probe for the Model 6824.

Does air temperature impact the velocity reading? Would the temperature difference impact the vane anemometer reading?

No, When using the probe within the ranges specified in the manual, there is no measurable effect of the air temperature on air velocity. Technically it does, but it is so minor, that the velocity readings will not be affected at all. Temperature outside the ranges will more likely have an effect on the lubricant used in the bearings.
