Digital Spirometer SP70B Handheld Pulmonary Function Lung Volume Device with Bluetooth, Infrared Measurement, FVC FEV1 PEF Testing for Hospital Clinic and Family Routine Use
SP70B Digital Spirometer for Lung Volume and Pulmonary Function Testing
The SP70B is a handheld digital spirometer designed for checking lung conditions using an infrared measurement mode. It measures FVC, FEV1, FEV1/FVC and PEF, and is intended for hospital, clinic and family routine testing. The device supports personal information setup including height, age and gender. It offers health status indication, Bluetooth transmission, data memory and case review. Up to 9999 cases can be stored. Power comes from two AAA batteries, with low battery indication and automatic power off. A real-time clock display is included. This compact unit measures 138 mm (L) × 63 mm (W) × 47 mm (H) and weighs 150 g with batteries. It is classified as internally powered equipment with a type BF applied part. The working current is 80 mA. The package includes a user manual and a disposable mouthpiece. This description covers the core specifications and practical functions stated by the manufacturer, without adding unsupported claims or invented features.
Features and Construction
The SP70B combines measurement functions, data storage and Bluetooth transmission in a hand-held format. Its infrared mode is used for measuring relative items. The device is powered by two AAA batteries and includes automatic power off and low battery indication. These features support routine testing in clinical and home environments where simple setup and review are needed.
Measurement Parameters
The spirometer measures FVC, FEV1, FEV1/FVC and PEF. These parameters are commonly used in pulmonary function testing. Volume range is 0–10 L and flow rate range is 0–16 L/s. Volume accuracy is ±3% or 0.05 L (whichever is greater). Flow rate accuracy is ±5% or 0.2 L/s (whichever is greater). These stated tolerances help users understand the device's measurement limits. The working current is 80 mA.
Data Memory and Review
The SP70B can store up to 9999 cases. Data memory and case review allow previous results to be accessed on the device. This supports routine monitoring when multiple tests are recorded over time. The real-time clock display helps keep track of when cases were recorded. Bluetooth transmission provides a way to send data to a compatible device.
Uses and Placement
The device is applicable for hospital, clinic and family use for routine testing. Its hand-held size and battery power make it suitable for settings where a compact spirometer is needed. Personal information setup allows height, age and gender to be entered before testing.
Clinical and Professional Use
In hospitals and clinics, the SP70B can be used for routine pulmonary function checks. The infrared measurement mode supports relative item measurement. Health status indication presents results in a clear way. The device stores cases for later review, which can be useful during busy clinic sessions. The user manual provides operating guidance.
Everyday Home Use
For family use, the spirometer offers a compact way to carry out routine lung function testing. It runs on two AAA batteries, so no mains connection is required. The automatic power off function helps conserve battery life. A disposable mouthpiece is included. The 150 g weight with batteries makes the unit easy to hold during testing.
Benefits and Buying Value
The SP70B provides a set of measurement parameters, data storage and Bluetooth transmission in one device. It is designed for routine testing rather than specialist diagnosis. The stated accuracy tolerances and ranges give clear technical limits. The package includes the essentials needed to begin using the device.
Reuse and Low Maintenance
The spirometer uses two AAA batteries, which are widely available. Low battery indication shows when power is running low. Automatic power off helps avoid unnecessary battery drain. The disposable mouthpiece is intended for single use. The source text does not state further maintenance requirements. Cleaning or disinfection instructions beyond the disposable mouthpiece are not provided in the source data.
