We will calibrate your British Pendulum to the latest standard, which is presently BS EN 16165:2021, which superseded BS 7976-2:2002. The fee for calibration is $980.00, plus the cost of shipping to and from our lab (which preferably can be done on your FedEx or UPS account). We have an ISO-certified facility do the alignment work, and then we complete the pendulum calibration procedure with our many years of training and experience in calibrating the different brands of pendulum testers from around the world. The pendulum should be calibrated annually, and for customers in the United States, we save you having to send your instrument to Europe for several weeks. The fee assumes that we don’t have to replace any missing or broken parts. The fee is just to complete the annual calibration procedure of a functioning and complete British Pendulum, which includes a calibration report for your records and a calibration sticker for your instrument. After twenty years of calibrating our own in-house pendulums we were found to be one of the world’s most accurate pendulum test labs in an international research study. Practical experience in calibrating and using pendulums for two decades makes us the perfect choice for calibrating your pendulum.
