Precision Acoustics D1602差分0.2 毫米模式水听器

Precision Acoustics Differential membrane 0.2 mm

差分膜，厚度为 0.2 毫米

For high-frequency ultrasound pressure measurements, where the minimisation of spatial averaging is important, this membrane is recommended.

在高频超声压力测量中，当需要小化空间平均效应时，推荐使用这种隔膜。

技术规格说明

* Precision Acoustics reserves the right to change the specification without notice.

* Precision Acoustics 保留在不另行通知的情况下更改规格参数的权利。

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).

保修政策：对于存在缺陷的产品，保修期为 12 个月，但用户自身造成的损坏不在保修范围内。如果设备在经过伦敦 NPL 校准后提出保修要求，那么将需要支付校准费用的一定比例作为补偿(例如，如果在保修期三个月后膜片出现故障，那么在 NPL 重新校准时的费用将相当于校准费用的 25%)。
