SDI Diagnostics

SDI Diagnostics is a longstanding manufacturer of pulmonary function testing equipment and consumables, trusted by pulmonologists, allergists, primary care practices, and school nurses for accurate, repeatable respiratory measurement. Honest Medical carries SDI's spirometry and peak flow accessories to keep your testing workflow moving without cross-contamination worries or calibration headaches.

The SDI Diagnostics Spirotube Peakflow Mouthpieces (29-7000) anchor this collection. These disposable mouthpieces are designed to pair with peak flow meters for asthma monitoring and lung function screening, giving each patient a fresh, single-use contact point. For clinics running back-to-back patients, that means simpler infection control and faster room turnover — you swap the mouthpiece, not the meter. Buyers typically ask whether these are universal-fit and whether they're latex-free; SDI's disposable design is built for standard peak flow meter compatibility, and using manufacturer-matched mouthpieces helps preserve the airflow readings your clinical decisions depend on.

If you're stocking a respiratory or asthma-management program, ordering mouthpieces by the box keeps per-test costs predictable and ensures you never delay a screening because a consumable ran out. These are wear-and-replace items, so quantity planning around your patient volume matters more than brand-hopping.

SDI Diagnostics sits alongside other trusted diagnostic manufacturers in our catalog. If you're comparing point-of-care and testing suppliers, you may also want to browse Clarity Diagnostics, Able Diagnostics Inc, and Copan Diagnostics for complementary specimen collection and diagnostic supplies.
