The Sonic Crackometer is a "plug and play" solution to hearing the unique sounds your beans make (called cracks) over the sound that your coffee roaster makes.
 
Exclusive CRC Lifetime Warranty

This is not just a "can and string".  This is definitely not a toy. The Sonic Crackometer is 100% stainless steel with special internal electronic components designed to accentuate the audio frequency cracking beans make, while minimizing all other extraneous audio frequencies.   This is a professionally made item which has benefited from our over 30 years of experience in acoustical design work.

Everything is included to attach the Sonic Crackometer to your roaster, whether your roaster is a BBQ Grill type roaster, air roaster, bread machine roaster, whirly pop roaster, or the type of roaster shown in the picture we have on site with the 2 pretty models (models, bag of beans, and roaster shown in picture not included in purchase).  Instruction manual included.  Unit plugs into 110 volts AC.
