The Cardiology IV stethoscope encompasses a redesign from the ground up featuring a brand new stainless steel chestpiece, brand new fully optimised paediatric and adult diaphragms unique to the Cardiology IV, the very latest generation long life tubing, a highly tuned bell side for instant low frequencies.

This is the upgrade you have been waiting for...

As with the Cardiology III, full acoustic range adult and paediatric auscultation is available through its newly designed dual head chestpiece. Simply rotate the central spline to alternate between the two sides for superior adult and paediatric auscultation. The brand new single piece diaphragms (unique to the Cardiology IV), have further optimised acoustic sensitivity, making all sounds clearer and easier to hear. The new long life binaural (two tubes in one) are the very latest specification, and latest materials, helping raise the warranty length to an industry leading 7 years. The selector spline is now recessed to allow a perfect flush fit with the binaural tube, now featuring a visual indicator for easy identification of the operational diaphragm.

Available in many different styles and colours in the drop-down menu.
