EDZP02 Micro Air Pump Suitable for sphygmomanometer Product Features · Maximum pressure time: 10 seconds Operating temperature & humidity: 5℃～45℃; 30%RH～85%RH Under the condition of rated voltage DC 3V, the time required for the pressure in a 100cc container to rise from 0 to 300mmHg. The allowable voltage range is 2.0V DC～3.0V DC. The allowable temperature range is 5℃～45℃; the humidity range is 30%RH～85%RH. When the rated voltage is used and the pressure reaches 300mmHg, the basic performance of the air pump will not be affected. Maximum current consumption: 450mA Maximum tested noise: 55dB Under the condition of rated voltage 3V DC, the current consumed when the pressure rises from 0 to 300mmHg. Noise test steps: Connect the pump's air outlet to the test device through a pipe, and place a noise meter at a distance of 30cm from the pump. Then under the rated voltage (3V DC), the maximum value of noise is measured when the pressure rises from 0 to 300mmHg. During the noise test, the pump should be placed on a 5cm thick foam board. The maximum pressure under rated voltage is 350mmHg. Positive pressure: 0.06Mpa Flow rate: 0.2L/H Power: 1W
