The CONTEC SP80B is a compact, handheld spirometer designed for evaluating and monitoring lung conditions. It utilizes an advanced infrared signal acquisition mode to measure relative pulmonary parameters. Featuring an integrated 2.8-inch high-definition screen, it provides real-time testing feedback alongside immediate visual flow-volume and volume-time graphs. The device operates seamlessly as a standalone unit or can sync via Bluetooth and USB to companion mobile apps and dedicated Windows PC software for clinical-grade record keeping and longitudinal trend analysis.

Comprehensive Parameter Tracking: Measures Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second ($FEV_1$), the $FEV_1/FVC$ ratio, Peak Expiratory Flow (PEF), and mid-flow rates ($FEF_{25}$, $FEF_{50}$, $FEF_{75}$, and $FEF_{2575}$).
Dual Transmission Modes: Effortless data uploading using integrated Bluetooth connectivity for mobile sync or a direct USB cable connection for PC transfer.
On-Screen Graphical Evaluation: Directly displays real-time flow-volume charts, volume-time charts, and historical trend lines without relying on a secondary device.
Smart Indicator Systems: Includes a built-in health state indication (traffic light style assessment), over-limit prompt sensors for volume/flow, and a dedicated 6-second expiration countdown indicator.
Integrated Calibration Routine: Features an integrated self-calibration function to guarantee long-term clinical reading accuracy.
High Autonomy: Operates perfectly as an independent standalone device; daily testing can be completed without ever loading a smartphone app or PC software.
Massive Built-in Memory: Avoids frequent clearing cycles by archiving up to 9,999 multi-waveform patient test records internally.
Ultra-Portable & Ergonomic: Weighing just 190 grams with an eco-friendly rechargeable lithium battery, it is highly optimized for travel and on-the-go checks.
One-Button Efficiency: Simplified user interface enables patients to initiate, capture, and store complex lung maneuvers with a single click.
Routine Clinical Monitoring: Utilized within hospitals and general physician clinics as an easy-to-sanitize tool for standard pulmonary screening and patient updates.
Home Respiratory Management: Well-suited for individuals managing dynamic conditions like Asthma, COPD, or Cystic Fibrosis who require daily, independent, and documented tracking of airway limits.
Treatment & Indicator Assessment: Used to measure the overall therapeutic success of respiratory prescriptions, evaluate post-surgical rehabilitation progress, or complete general physical routine tests.
