Warranty and Product Support
Fluke Biomedical warrants this instrument against defects in materials and workmanship for one year from the date of original purchase OR two
years if at the end of your first year you send the instrument to a Fluke Biomedical service center for calibration. You will be charged our
customary fee for such calibration. During the warranty period, we will repair or at our option replace, at no charge, a product that proves to be
defective, provided you return the product, shipping prepaid, to Fluke Biomedical. This warranty covers the original purchaser only and is not
transferable. The warranty does not apply if the product has been damaged by accident or misuse or has been serviced or modified by anyone
other than an authorized Fluke Biomedical service facility. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR PURPOSE,
ARE EXPRESSED OR IMPLIED. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.
This warranty covers only serialized products and their accessory items that bear a distinct serial number tag. Recalibration of instruments is
not covered under the warranty.
This warranty gives you specific legal rights and you may also have other rights that vary in different jurisdictions. Since some jurisdictions do
not allow the exclusion or limitation of an implied warranty or of incidental or consequential damages, this limitation of liability may not apply to
you. If any provision of this warranty is held invalid or unenforceable by a court or other decision-maker of competent jurisdiction, such holding
will not affect the validity or enforceability of any other provision.

Introduction
The VT650/VT900 Gas Flow Analyzer (the
Analyzer or Product), is a general purpose gas
flow analyzer with special features for testing
mechanical patient ventilators. The Analyzer
measures bi-directional air flow, high and
differential low pressure, barometric pressure,
Oxygen concentration and airway pressure,
airway temperature and airway humidity. The
VT900 also measures ultra-low flow (±750 ml/
min) and ultra-low pressure (0 mbar to 10 mbar).
The Analyzer can be controlled externally using
USB commands or automated with available
software. The Analyzer operates on a
rechargeable Li-Ion battery or external power
supply for stationary or portable use. All figures
show the VT900 unless otherwise noted.
Key Features
• Full range, bi-directional air flow and volume
channel
• Ultra-low flow and pressure ranges (VT900)
• High pressure, vacuum and differential low
pressure
• Airway pressure, Oxygen concentration,
temperature, and humidity
• Barometric pressure
• External trigger input (VT900)
• Rechargeable Li-ion battery with up to
8 hours battery life
•USB port
• Customizable profiles that can be saved
• Numerical and graphical screens with real
time data
• Automation software available
• On-board memory
