PCE-P01 is a portable handheld digital differential pressure manometer used to measure differential pressure in pneumatic, compressor and pump installations, valves, tanks and heating, ventilation and air conditioning (HVAC) systems. The PCE-P01 displays min \/ max \/ average values right on the meter's screen for comparison against current measurement values.","In addition, the PCE-P01 differential pressure manometer features real-time data-logging capabilities with an adjustable interval from 1 second to 24 hours. The device comes with 4 x 30 cm \/ 11.81\" silicon tubes, 1 x 9 V block battery and 1 x AC power adapter. Also included in the delivery contents are PC-compatible software and a USB cable. The software can be used to detect and document pressure fluctuations, and to display the data graphically or in a table. For real-time data recording, simply connect the differential manometer via USB to your computer, and save the measured values ​​according to your selected time interval. You can then calculate average values ​​directly in the software or export the saved data to Microsoft Excel.
