Contec SP-80B Bluetooth Spirometer. It is an affordable, reliable portable spirometer suitable for use both in the clinic and for home visits. The recordings can be transferred to the computer database.

It features internal flash memory for data storage and the transfer can be completed either wired via USB or wirelessly via Bluetooth.

The color LCD screen with backlight measures 2.8" and displays flow-volume and volume-time waveforms for immediate diagnosis.

It measures and calculates all basic and important respiratory parameters such as:

• Forced Vital Capacity (FVC)
• Forced Expiratory Volume in one second (FEV1)
• Peak Expiratory Flow (PEF)
• Nine total parameters
• FVC / FEV1 ratio
• Dynamic Vital Capacity (FVC)
• Forced Expiratory Volume (FEV)
• FEV1 and FVC ratio (FEV1%)
• 25% of FVC flow (FEF25)
• Mean flow between 25% and 75% of FVC (FEF2575)

It has a built-in lithium battery with power status indication and automatic shutdown after 1 minute of inactivity.
