The Traqc-9 P is the best solution for each pressure calibration job with an accuracy of 0.02%. The option for a second pressure sensor offers you the flexibility to accurate measure a wide range of pressures with the same instrument. You can choose the most suitable range for general calibration tasks, or a wider range specifically for critical measurements. The option for a PCB mounted barometric reference sensor increases this flexibility even more. The Traqc-9 allows you to power your transmitters and measure the common mA or V output signals precisely.
