Description
Overview
This is a replacement flow sensor for the ndd EasyOne Pro and EasyOne Pro LAB pulmonary function systems. It uses ndd's ultrasonic transit-time TrueFlow measurement, which has no moving parts in the flow path and does not need calibration during its lifetime. Order it to replace a damaged sensor and return the system to service.
Key Features
- Ultrasonic transit-time measurement gives contact-free, resistance-free flow sensing with accuracy independent of gas composition, pressure, temperature and humidity.
- No calibration required during its lifetime, so routine work is limited to optional syringe cal-checks.
- Low resistance (<1.5 cm H2O/L/s at 14 L/s) keeps the sensor from affecting patient effort during testing.
- Same part for EasyOne Pro and Pro LAB.
Configuration and Package Contents
- One ndd flow sensor, part number 3000-50.5.
- Single-use Spirette mouthpieces and Barriettes sold separately.
