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%)。
