| □ 3 Measurements in one instrument Air flow: CMM( M3/min) and CFM(FT3/min) Air velocity: m/s, ft/min, km/h, knots, mile/h Air temperature: Degree C and F □ 3 air flow mode: Instant, 2/3rd velocity Max. Average □ Use Low friction ball vane wheels to make sure high accuracy in high and low velocities □ Recall function for maximum and minimum record □ Data hold function □ High accuracy and special function built-in microcomputer circuit design □ Auto power off, Low battery indication. □ Use fast-response-time thermistor sensor for temperature measurement □ Separate probe for different environment measurement |
