SP70B Digital Spirometer – Handheld Lung Function Tester with Bluetooth and 10L Volume Range

The SP70B digital colour spirometer is a portable lung function testing device designed for routine pulmonary assessments in hospitals, clinics, and home settings. Using infrared technology, it measures forced vital capacity (FVC), forced expiratory volume in one second (FEV1), the FEV1/FVC ratio, and peak expiratory flow (PEF). With Bluetooth connectivity and mass storage for up to 9999 patient cases, this device supports effective long-term monitoring. Its compact dimensions (138 mm × 63 mm × 47 mm) and light weight (150 g with batteries) make it easy to carry between consultation rooms or to a patient's bedside.

Key Features and Measurement Capabilities

This spirometer covers a volume range of 0 to 10 litres and a flow rate range of 0 to 16 litres per second, with accuracy levels suitable for routine clinical use (volume: ±3% or 0.05 L; flow: ±5% or 0.2 L/s, whichever is greater). Safety classification is internally powered, type BF applied part.

Comprehensive Lung Parameters

Measure FVC, FEV1, FEV1/FVC ratio, and PEF in a single test session. These parameters are essential for detecting obstructive and restrictive pulmonary patterns. The device provides clear health status indication based on your personal data, including height, age, and gender.

Bluetooth Data Transmission

Transfer test results wirelessly to a connected device for record-keeping or further analysis. The Bluetooth feature supports efficient sharing with healthcare providers without manual data entry.

Mass Storage and Review

Store up to 9999 patient cases onboard, with a case review function to access historical data. This is valuable for tracking changes in lung function over time, especially for chronic conditions such as asthma or COPD.

Design and Practical Operation

The SP70B is built for straightforward, everyday use. It includes a real-time clock display, low battery indication, and automatic power-off to conserve battery life.

Power Supply and Battery Life

Operates on two AAA batteries with a working current of 80 mA. The low battery indicator alerts you when replacement is needed, preventing unexpected shutdown during testing.

Compact and Portable Build

At just 150 g (with batteries) and measuring 138 × 63 × 47 mm, the device fits easily into a coat pocket or a small medical bag. This portability suits community health visits, home care, or clinical settings with limited workspace.

Disposable Mouthpiece System

Each test uses a single-use mouthpiece to maintain hygiene and reduce cross-contamination risk. A disposable mouthpiece is included with the device, and replacements can be sourced separately.

Why Choose the SP70B Spirometer

The SP70B offers a balanced combination of measurement accuracy, data capacity, and portability for routine pulmonary function testing. Its Bluetooth capability and large storage make it suitable for both individual and small-group practice.

Clinical and Home Use Versatility

Suitable for hospital pulmonary departments, GP clinics, and home monitoring—particularly for patients managing chronic respiratory conditions. The device supports personal information setup to generate age- and gender-adjusted results.

Practical Maintenance

With no complex cleaning procedures required (the mouthpiece is disposable), the device demands minimal upkeep. The automatic power-off prevents accidental battery drain, and the durable ABS casing withstands regular handling.

Value Through Reuse and Data Management

The ability to store up to 9999 cases with Bluetooth export reduces administrative overhead and supports longitudinal patient monitoring. This is a practical advantage for clinicians tracking treatment efficacy over several visits.
