Does it record at 200hz? the description mentiond 500ms, which is 2 hz, and it also mentiond 20ms, which is 20 hz. 200hz would be 1 sample/5 ms.

Thank you. As per information from the data sheet, the Acceleration Sampling Rate (Data Logger) is mentioned as 200Hz.

Hello, What is the difference between vibration data logger and G force data logger?

HelloA vibration data logger will log standard vibration parameters: displacement, velocity and acceleration. The VB300 G force data logger logs acceleration specifically in units of g force. The VB300 user guide is available here for you further review:http://www.extech.com/display/?id=14797Best Regards.

I need to measure vibration vs frequently of the vibrations. Will this chart these?

This device will only give you the g-force value with a time and date stamp. It won't give you the frequency of vibration.

What is the maximum number of readings? I am looking to install for about 6 months with readings every 5 minutes for a total of 45,792 readings.

Hello Claire,Thank You for your inquiry regarding the VB300. A 5 minute sample rate will get you about 3.5 months worth of datalogging, there is also a limitation of a 1000 hour battery life. The User Manual is here if you would like to review specifications further.http://www.extech.com/resources/VB300_UM.pdfBest Regards

I needed it for a temperature test and it works just like more expensive versions

This product works well. I needed it for a temperature test and it works just like more expensive versions.

No indication of testing, calibration or accuracy.

A signed and dated certificate of calibration would have added to my confidence in the readings obtained. As received, it was assembled with no indication of it being tested.
