These stethoscopes use the patented single sided chestpiece design that combines both the bell and diaphragm modes into the same side of the chestpiece. Light pressure detects low frequency sounds.
Firm pressure produces a diaphragm response detecting high frequency sounds.
The single sided chestpiece allows detection of both frequencies without changing position and losing a landmark. All of the Littmann veterinary stethoscopes feature a patented diaphragm that assures high acoustic sensitivity and consistent frequency responses. They also feature lightweight headsets and soft-sealing ear tips which help ensure comfort and a good seal in the ear. Use Tunable technology provides convenience, versatility and enhanced acoustics. You control bell and diaphragm modes by pressure on the chestpiece rather than turning it over.
