Laboratory tests have demonstrated that shorter tubing provides a better acoustic response. In reality, most people do not have the hearing acuity to detect any performance impact from changes in tubing length unless there is a dramatic change in that length. In fact, the acoustic transmission of lower frequencies, with their longer wavelength, benefit slightly from increases in tubing length. Longer tubing tends to make the scope more convenient to use, but also adds a bit to its weight. Bottom line - tubing length is generally a matter of personal preference.

Two-tube stethoscopes, such as the ADSCOPE 600, 601, 606 and 641 (the 600, 601 and 606) feature our two-tube in one design, while the 641 actually has two separate tubes) provide better stereo separation allowing you to hear the subtle characteristics of heart sounds and murmurs more distinctly. The heavier tubing also filters out the distracting noise typical of a busy medical environment.

Generally speaking, to attenuate certain frequencies. The flat side is equipped with a membrane that is generally referred to as the diaphragm side. The conical or bell shaped side is called the bell. Body sounds generally fall within a frequency range of 50 to 2000 Hz. The diaphragm side is designed to attenuate the lower frequency and accentuate higher frequencies within this range - from 500 to 1000 Hz. The bell side is designed for lower frequencies - from 50 to 500 Hz.

To maximize performance of your ADC scope, you want to optimize the seal from the scope's chestpiece to your ears. Any leakage or obstruction will impede performance. First, align the binaurals properly so that the eartips point towards the bridge of your nose. On PROSCOPE series scopes and the ADSCOPE 641, you will need to adjust the binaurals to align the eartips correctly. On ADSCOPE series scopes, the binaurals are pre-angled 15° forward for a snug fit. But, you must make sure to position them correctly - eartips FORWARD. Next, adjust the binaural tension.

Older style Adsoft™ PVC eartips (included on all Adscope® stethoscopes manufactured prior to 2014) are equipped with a threaded insert. If your stethoscope is equipped with threaded eartips, periodically tighten the eartips to ensure security. You may apply Teflon™ tape, or clear nail polish to the binaural thread to improve security without compromising scope performance or jeopardizing warranty coverage. Do not apply the adhesive to the eartips.

Under certain conditions, the PVC tubing used in our ADSCOPES when exposed to atmospheric ozone, combined with skin oils can become rigid. If you wear your scope around the neck, try not to let it come in contact with the skin. In addition, periodic treatment with a vinyl protector (such as Armor All) once a month may delay the process. Should the tubing in your ADSCOPE become rigid, return to ADC for complimentary warranty service.

The Diagnostix 2100 and Advantage 2200 fingertip pulse oximeters can be used on children at least one year old or weighing at least 28 lbs (13kg).  The Adimals 2150 fingertip pulse oximeter is designed specifically for children with a finger thickness of  0.2” to 0.63” (5.0mm to 16.0mm).

ADC partners with the world's leading ISO 9000 subcontractors to produce components incorporating proprietary features and technologies on an exclusive basis. ADC then inspects, assembles, and packages the finished products in its Hauppauge, NY facility. Some products may have as many as 6 different countries of origin!

You can return any ADC brand or ADC manufactured product directly to ADC for warranty service. Products that are still under warranty will be serviced free of charge, and those products that are no longer covered under warranty will be repaired for a nominal fee (typically the cost of labor and parts).
