Bearing Checker is a portable instrument for fast and easy measurement of bearing condition in preventive maintenance. The instrument is push button controlled and basic measurement data are entered manually. Bearing Checker measures shock pulses, either with a built-in probe (BC200) or with an external sensor. The instrument can also be used as an electronic stethoscope for detecting machine sound irregularities. Measuring results are indicated by green-yellow-red symbols along with detailed evaluation of measurement values. Measurement results can also be transferred to a file for further processing, e.g. in Microsoft Excel.
