BVB-8207SD 4 channels VIBRATION RECORDER

* 4 channels vibration recorder, use SD card to save the 4 channels' data along with time         information, paperless.

* Applications for industrial vibration monitoring : All industrial machinery vibrates. The level     of vibration is a useful guide to machine condition. Poor balance, misalignment &                   looseness of the structure will cause the vibration level increase, it is a sure sign that the       maintenance is needed.

* Channels no. : 4 channels ( CH1 to CH4 ) vibration measurement.

* Frequency range 10 Hz - 1 kHz, sensitivity relative meet ISO 2954.

* Professional vibration meter supply with vibration sensor & magnetic base, full set.

* Metric & Imperial display unit

* Acceleration, Velocity, Displacement measurement.

* RMS, Max hold, Peak value measurement.

* Max. Hold reset button, Zero button.

* Wide frequency range.

* Data hold button to freeze the desired reading.

* Memory function to record maximum and minimum reading with recall.

* Separate vibration probe with magnetic base, easy operation.

* Real time SD memory card Datalogger, it Built-in Clock and Calendar, real time data               recorder , sampling time set from 1 second to 3600 seconds.

* Manual datalogger is available ( set the sampling time to 0 ), during execute the manual       datalogger function, it can set the different position ( location ) No. ( position 1 to position     99 ).

* Innovation and easy operation, computer is not need to setup extra software, after               execute datalogger, just take away the SD card from the meter and plug in the SD card         into the computer, it can down load the all the 4 channels measured value with the time         information ( year/month/date/ hour/minute/second ) to the Excel directly, then user can     make the further data or graphic analysis by themselves.

* SD card capacity : 1 GB to 16 GB.

* LCD with green light backlight, easy reading.

* Can default auto power off or manual power off.

* Data hold, record max. and min. reading.

* Microcomputer circuit, high accuracy.

* Power by UM3/AA ( 1.5 V ) x 8 batteries or DC 9V adapter.

* RS232/USB PC COMPUTER interface.

* Include 1 PC vibration sensor, VB-83.

* Extra vibration sensor, VB-83 can be ordered. When change the VB-83, it is not necessary     to make calibration again.
