Operating Principal:-

• Hotwire anemometer A wire is continuously heated at a superior temperature than ambient and continuously cooled by airflow. Constant temperature is maintained by a regulation circuit. The heating current is proportional to the airflow velocity.

Maintenance:-

• We carry out calibration, adjustment and maintenance of your instruments to guarantee a constant level of quality of your measurements. As part of Quality Assurance Standards, we recommend you to carry out a yearly checking.

Measuring Elements:-

• Hotwire air velocity: thermistance with a negative temperature coefficient. Ambient temperature: NTC sensor
  

Display:-

• 4 lines, LCD technology. Dimensions 50 x 36 mm. 2 lines of 5 digits with 7 segments (value) 2 lines de 5 digits with 16 segments (unit)
