Technical Specifications
Microcontroller based face velocity measurement device with the unidirectional flow sensor, measurement against set point and indication of high or low value. Alert with audio visible alarm when out of range of velocity and for the reverse direction airflow. The device is with glass front and features touch buttons interface and relays for controlling light and exhaust fan contactor. The illuminated digital OLED display 1.3 inch shows the operating status and the face velocity as a numeric value in SI and Imperial system. .
