* Precision Acoustics reserves the right to change the specification without notice. Warranty: membranes 12 months against defective product but not damage caused by user. If a warranty claim is made on devices that have been calibrated at NPL, London, a charge will be made for the used part of the calibration (e.g. in the event of failure of a membrane at three months the charge for recalibration at NPL is 25% of the calibration charge).
