393 Series units are useful when measuring bridge and civil structures, building vibration, floor and foundation monitoring, optical or MRI instrument studies, semiconductor manufacturing, or site surveys for sensitive equipment.
If interested in low frequencies, make sure the signal conditioning and analyzer used are specified to match. For best measurement clarity, seismic accelerometers should be used with a unity gain, battery powered signal conditioner.

Notes on Calibration
Calibration data is provided electronically (on CD or USB memory stick) or as printed copies, depending on quantity rented and end-user preference.
The Modal Shop has internal calibration intervals set for most test products at 1 year. ANSI/ISO/IEC 17025:2000 makes clear that it is the responsibility of the end-user organization (in this case, the renter) to determine the appropriate calibration
interval under the requirements of its own quality system. Per this, calibration certificates of rented equipment have "calibrated on" dates, but blank "calibration due" dates. Rentals ship with a customer specific expected return date in mind - if
equipment is expected out for 5 months, the last calibration date will be within the past 7 months. Calibration to additional standards (e.g. Z540 or specific FAA requirements) are possible, but there may be an additional charge.
The Modal Shop's Scope of Accreditation can be found here. An example of a calibration certificate can be found here. Please contact us with questions or if a different calibration will be needed for your rental sensors.
