They measure the air speed by calculating how fast the probe sensor is being cooled by the airflow.
The principles behind all hot-wire anemometers may be the same, but the quality varies. Simply put, with our temperature compensation sensor, our Anemomaster Professional is highly accurate with an accuracy of +/- 2%. This is due to several factors:
1) We calibrate the temperature compensation sensor, as well as the velocity sensor. Other manufacturers only calibrate the velocity sensor.
2)We use special high-quality materials, like our platinum sensors, that increase accuracy.
3) Our manufacturing facility uses not 1, but 4 specialized wind tunnels to test and calibrate our anemometers. These wind tunnels include a low velocity tunnel, high tunnel velocity and a variable temperature wind tunnel.
4) We’ve been making anemometers for over 80 years. During that time we’ve perfected our knowledge and refined our manufacturing process to produce a research-grade instrument.
Yes, all our instruments come with a calibration certificate.
Kanomax recommends annual calibration to ensure accuracy.
You can measure clean air between -4 and 158°F (-20 to 70°C) in an environment with no visible condensation. (Please note: the temperature range given is for the probes).
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.
