Rapidly obtain accurate measurements of airflow distribution in HVAC systems. The versatile design of the AFH electronic balometer allows easy data acquisition on ceiling, wall-mounted, and floor-level diffusers, working in supply or exhaust. View measurements easily on the large LCD display, and store up to 100 readings in its nonvolatile memory for later analysis. Download data to your computer via the A-547 RS-232 cable (sold separately). Eliminating time-consuming calculations, this instrument utilizes a sixteen-point measurement array to display flow in cfm, m³/h, or l/s. Light weight and easy to handle, the AFH requires only one person to operate. Standard 2' x 2' hood fits over most standard grills and exhausts. Additional hood expansion kits are sold separately. Each unit includes: AFH meter, 2' x 2' hood, rugged carrying case, four universal hood-support poles, four AA batteries and calibration data sheet.
