«We at Vaisala have worked many years manufacturing and calibrating measurement instruments. We have gained lots of calibration experience, and working with our clients has revealed a need to increase common knowledge of what calibration is all about. We put this book together to share some of our knowledge and some commonly known basics. We hope our readers find these pages useful.»
«Мы работаем много лет в городе Вайсала над разработкой и калибровкой средств измерений. Мы провели множество калибровочных экспериментов и работаем совместно с нашими клиентами над всеобщим распространением знания о том, что такое калибровка. Мы объединились, чтобы написать эту книгу, вложив в нее свои знания и некоторые общеизвестные истины. Мы надеемся, что наши читатели сочтут её полезной.»
