Listening to machine sounds to determine the probable source of an abnormal noise is one of the most widely used methods in maintenance departments across all branches of industry. SPM introduces its Electronic Stethoscope ELS14 to aid the sound source search.

The stethoscope is a practical and easy-to-use listening device that helps pinpoint the source of mechanical noise in a broad range of applications. Bearing condition, gear and pump noise and electric relay operation are just a few of the many sounds which can be identified, amplified and assessed.

High, middle or low filters can be selected in order to single out relevant frequencies. With the push of a single button, the appropriate filter is applied. Volume is adjusted in the same simple way. Ear defenders effectively shut out ambient noise.

This lightweight one-hand operation stethoscope comes with an internal SD card and recording capabilities, enabling sounds to be played back from the device and stored as sound files for further evaluation or future comparison.

Some features of the Electronic Stethoscope ELS14 include:

• Frequency range of 20 to 30 kHz
• Filters of High, middle and low
• Casing of PC/ABS, IP55
• Weight of 295 g incl. batteries and 60 mm probe
• Batteries and SD-card, probe 60 and 290 mm, headphones with ear defenders and a convenient carrying case.
