CFM/CMM Thermo-Anemometer + IR Thermometer
The HD300 can simultaneously display of Air Flow in CFM/CMM or Air Velocity Plus Ambient Temperature and features an Infrared Thermometer that measures surface temperatures to 932 degrees F (500 degrees C) with 30:1 distance to target ratio and laser pointer.
Additional Features
The HD300 has easy to set Area dimensions that are stored in the meter's internal memory for subsequent measurements. Other features include: large (9999 count) LCD backlit display, 20-point average for airflow, and a rugged, double-molded housing.
How Does An Anemometer Measure Moving Air?
Anemometers measure moving air with a rotary sensor that acts very much like a weathervane and can be likened to the blades of a fan. The vane freely rotates in response to airflow, and as the air moves through the vane the blades turn in proportion to the speed of the air.
What Is CFM/CMM?
Cubic Feet per Minute (CFM) or Cubic Meters per Minute (CMM) are units of measure for air volume measurements. This is a measurement of the quantity of moving air through an air duct, passageway, or enclosure. In order to determine this, the area of the duct must be measured. The area value (in ft2or m2) is entered by the user, by pushbutton or keypad into the meter and an air velocity is determined.
