The ADM-880C AirData multimeter measures air velocity, temperature, pressure, and airflow. During velocity or flow readings, the meter automatically measures the local temperature and barometric pressure and corrects for local air density. The multimeter stores 2,000 readings in 25 user-selectable groups and calculates the average, sum, minimum, and maximum of the readings in each group. The time and date of each reading is recorded. The meter can be programmed by the user to take readings at selected intervals. The user can select the start and stop time of the reading sequence or program the meter to take a specified number of measurements, then stop. The data can be downloaded directly to a printer or a computer spreadsheet such as Microsoft® Excel.
