NDD 2030-2 Easyone 3-Liter Calibration Syringe

In stock
Features include: 3 liter capacity, use with easy one spirometer.

While the easyone does not require calibration, it is important to note that the american thoracic society, NIOSH/OSHA, and others recommend that the accuracy of the spirometer be verified on a regular basis. This verification is easily done using the 3 liter syringe. In addition, the ultrasonic flow measurement is inherently independent of temperature, humidity, pressure, and gas composition.


  • The easyone spirometer determines flow by measuring the flight time of ultrasonic pulses
  • The time measurement is performed digitally using a precision quartz clock
  • The transducers that are used for this time measurement are mounted outside of the flow tube
  • Changing the flow tube does not change the characteristics of the transducers
Additional Specifications:
  • Product Type: Calibration Syringe
