FAQs
How do hot-wire anemometers measure air velocity?
Hot-wire anemometers operate on the principle of convective heat transfer. The sensor contains a tiny heated wire that is cooled by the passing airflow. The system precisely measures how quickly the wire cools, which directly correlates to the air velocity. The faster the air moves, the more heat is removed from the wire, allowing for highly accurate velocity calculations.
Can I measure airflow in non-standard environments?
The 1550/1560 Series is designed for clean air measurements between -4 and 158°F (-20 to 70°C) in environments without visible condensation. The system should not be used with flammable or corrosive gases, as the heated sensor could pose a safety hazard or sustain damage. While it's technically possible to use the instrument in non-flammable, non-caustic gases, the calibration is specifically for air, and measurements in other gases will not be accurate.
How do I order a multi-channel system?
Due to the highly customizable nature of the 1550/1560 Series, it's recommended to consult with a Kanomax representative or authorized distributor to configure a system that meets your specific requirements. The system requires matching the main unit (1550 or 1560) with appropriate modules, probes, and cables for your application.
How often does the Applied Physics anemometer require calibration?
For most applications, annual calibration is recommended to maintain measurement accuracy. However, organizations with specific Standard Operating Procedures (SOPs) or regulatory compliance requirements may need more frequent calibration. Kanomax provides NIST-traceable calibration certificates with all new instruments and offers recalibration services to ensure ongoing measurement reliability.
