Precision Measurement Microphone and Preamplifier Rental

Free-field | Pressure | Random Incidence | Intensity Sets

Condenser microphones offer IEC Type 1 performance and are sorted below by Response. Choose from Free-field, Pressure, Random Incidence, or Intensity Sets.

A note on Polarization voltage:
0 V condenser microphones are often noted as Prepolarized. They feature a modern design, operate from standard ICP® sensor power – the same as ICP® style accelerometers and pressure sensors. 0 V microphones offer a lower per-channel cost when cabling and signal conditioning is considered. 200 V microphones are Externally Polarized and require a separate 200 V power supply and expensive multi-pin cabling.

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.
