They measure the air speed by calculating how fast the probe sensor is being cooled by the airflow.
Yes, all our instruments come with a calibration certificate.
Annual calibration is recommended to ensure accuracy. However, this can vary based on how often the anemometer is used and the environments it’s used in. Also, some companies have an SOP in place that specifies how often the instrument will need to be serviced. More specifically, regulatory compliance may dictate the calibration interval.
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.
We have three multi-channel anemometers: The 1570 is a 4-channel anemometer that just measure air velocity. The 1550 and 1560 have more channels (16 and 6 respectively) and can also measure temperature and relative humidity. These two units can be operated in a cascade configuration where multiple units can be chained together to create more channels.
These systems are designed for flexibility so you can buy exactly what you need for your specific application. The 4-channel 1570 is easy to order as it requires only the main unit and then whichever probes and cables suit your application. The 1550 and 1560 are a bit more complex as these instruments are composed of the chassis, modules, cables and probes. Each probe must have the correct corresponding module installed in the chassis to plug into. We suggest calling your distributor or Kanomax to get assistance with ordering these systems.
