Extremely high accuracy airflow velocity readings

Product Features
  • Automatically calculates volume flow in CFM (cubic feet per minute) or CMH (cubic meters per hour)
  • Enter duct width, height, or diameter in either inches or centimeters
  • Duct dimensions are stored in memory on turn-off and do not need to be re-entered
  • Store up to 10 different commonly-used duct sizes for quick, convenient readings in the field
  • Rated from 50 to 7800 feet per minute
  • Industrial grade enclosure and probe
  • Large display with backlight
  • Easy to use keypad
  • Also displays airflow in feet per minute and meters per second
  • IP40 rated (IP65 with OPTIONAL Boot & Seal)
  • ±1% of READING accuracy (AP275)
  • High Accuracy: +/- 1.0 % of reading
  • 40 fpm of air velocity sensitivity
  • Temp. Measurements from -22 to 212F
  • Three output options available:
    1. Analog voltage
    2. USB
    3. RS232
  • Rugged metal probe and vane
  • This is a high quality instrument which provides accurate air velocity and volume flow measurements in the harshest environments
  • The user can easily enter the size of the duct opening and the 6812 automatically calculates the volume flow rate from the duct
  • The duct size is automatically stored in memory on turn-off and up to 10 unique duct sizes can be stored and recalled for frequent use
  • Includes NIST-traceable calibration certificate*

*NIST TRACEABLE CALIBRATIONS are performed at our facility in ANDOVER, NJ

Yes, all our instruments come with a calibration certificate.

Kanomax recommends annual calibration to ensure accuracy.

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.

No, the temperature sensor is built into the velocity probe for the Model 6813.

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.
