The Kanomax 6820 series is a family of high‑accuracy rotating vane anemometers designed for professionals who demand reliable air velocity and volume flow measurements. With a class‑leading accuracy of ±1.0% of reading, these instruments are ideal for HVAC system balancing, laboratory airflow control, indoor air quality (IAQ) assessments, and industrial hygiene monitoring.

The series offers three models to suit different measurement needs:

• 6822 – Measures air velocity and automatically calculates volume flow (CFM or CMH).
• 6824 – Adds temperature measurement to the 6822’s capabilities.
• 6825 – Further adds relative humidity, providing a complete environmental monitoring solution.

All models feature a 2.75‑inch rotating vane probe with a measurement range of 40 to 3800 FPM (0.2 to 20 m/s) and resolution of 1 FPM or 0.01 m/s. The temperature sensor covers -4°F to 212°F (-20°C to 100°C) with high accuracy, and the humidity sensor (6825) ranges from 5 to 95% RH with ±2% RH accuracy.

Field efficiency is enhanced by the ability to store up to ten commonly used duct sizes directly in the meter, allowing instant volume flow readings without re‑entering dimensions. For data logging and remote monitoring, the 6820 series offers multiple output options: analog voltage, USB, and RS232.

Built for rugged daily use, the Kanomax 6820 series comes with a one‑year warranty and is the trusted choice for HVAC contractors, facility engineers, and environmental health professionals.
