serves to calibrate suction pump at the hospital. This tool is very important to the hospital because this tool can know suction pump inadequacies of the tool itself. Checking eligibility dipayakan medical devices for more thorough and accurate, and therefore needed a tool for calibration suction pump with the accuracy of measurements that have been through the test the feasibility of the tool by using a pressure meter standardized. Here the authors make calibrator suction pump which results will be measured and compared with the Digital Pressure Meter (DPM), which has been standardized, Modul use the system microcontroller and display with 16x2 lcd. "Calibrator Portable Suction Pump-Based Microcontroller ATMega 16" compared to the digital pressure meter to determine the accuracy of the time operated. The average value obtained from the error of taking the measurements at six points (-100mmHg, -200mmHg, -300mmHg, -400mmHg, -500mmHg, - 600mmHg) and 20 measurement with which is equal to 0,00343677%. __________________________________________________________________
