A stethoscope is a handy and necessary tool to locate noises in vehicles and machinery. It’s an excellent tool for preventative maintenance and can help diagnose a wide variety of issues, especially when there are lots of moving parts involved. It makes the job easier and speeds the process to ensure faster solutions. There are a variety of stethoscopes on the market, but how do you know which one is right for you?
There are a few different factors you should consider.
- Rod probe and clamp
Stethoscopes are often available with different sizes of rod probes. The majority of stethoscopes come with two probes in different sizes. The standard is generally 70mm and 220mm. So, if you need a specific probe length, be sure to check what is available.
Likewise, many will come equipped with more than one clamp. This allows you to examine several specific components at one time. You can mount clamps on the brake forks, injectors, damper springs, axle bearings, and more. All of these must be checked for an accurate diagnosis. The stethoscope serves that purpose.
- Frequency Range
When shopping online for a stethoscope, you will notice various frequency ranges. Industrial stethoscopes have a wide range, with the most common being 15kHz. When you choose a digital or electronic stethoscope, you will find the measurement results on the LED display. You can adjust the environmental volume by setting the output volume at the right level. They can dampen noise, reduce background noise, and amplify sound.
For accurate results, a stethoscope should be calibrated. More importantly, you should be able to re-calibrate it if necessary. Any instrument you purchase should meet in-house specifications and meet compliance expectations for legal purposes. When you invest in a tool for your business, you must know it provides accurate and reliable results.
Industrial stethoscopes are not suitable for medical purposes. They are intended for diagnostics in the automotive or industrial setting. When using an industrial stethoscope, it’s important to ensure you do not expose the tip to extreme shocks as it can damage the device.
The Right Choice
The best way to see if a stethoscope is right for you is to try it out to see, hear, and feel how it works for your intended purpose. How much and how well can you hear? See how easy or difficult it is to adjust the headset. Hold the unit by the headset and allow it to hang vertically. Are there bends or kinks that make it more difficult to use? This can indicate stiff tubing, which will tug on the ear tips and make it challenging to use.
A headset should be somewhat adjustable so each user can adjust it for their comfort. For a standard stethoscope, it’s worth checking to ensure the ear tips snap tight. This will ensure maximum safety and performance. For electronic stethoscopes, the cushioned headphones will maximise sound, and keep environmental noise at bay as well.
