Measure: MultiCal

The MultiCal is NASA’s DMM for the Space Shuttle and International Space Station. These modules convert your meter into an accurate pressure measuring system.

NASA's DMM pressure solution! MultiCal EC Declaration of Conformity DNV Certificate

The MultiCal pressure module is chosen by NASA for the Space Shuttle and International Space Station. These modules convert your meter into an accurate pressure measuring system. The analog signal is clean, accurate and fast, so you can even use MultiCals with oscilloscopes to measure dynamic pressure.

  • Converts a meter into a high accuracy pressure measuring system
  • 1k Hz pressure response
  • Connects directly to oscilloscopes
  • Lightweight
  • Runs on single 9V battery
  • Millivolt output
  • Comes with a dual banana jack cable and holster case

Applications

  • Connects to DMMs or to oscilloscopes
  • 1k Hz pressure response
  • Dynamic pressure measurements in automotive and aerospace braking systems

Included with every new MultiCal Pressure Module is an A2LA calibration certificate.
