В настоящее время большой популярностью пользуются цифровые лазерные тахометры, являющиеся просто незаменимыми приборами при выполнении операций регулировки электроблоков зажигания автомобильного двигателя, при определении порогового значения срабатывания экономайзера и др.

Высокоточный тахометр лазерного типа DT-0071 измеряет скорость вращения в интервале от 30 об/мин до 99999 об/мин на расстоянии до 1,5 м.

Областью применения тахометра DT-0071 является проведение высокоточных измерений скорости вращения предметов, находящихся на удаленном расстоянии, посредством лазера. Прибор имеет цифровой лазерный метод измерения – проводится анализ лазерного сигнала, отраженный от объекта. DT-0071 оснащен большим, удобным для чтения экраном и возможностью проведения тестирования на большом расстоянии.

Имеется встроенная память измеряемых показателей. Все измерения проводятся с точностью ± 0,02% при рабочей температуре 0-70 °C.

Питание ведется от трех батарей ААА по 1,5В. Габариты тахометра – 72мм х 136мм х 33мм, вес – 146 г.

Сегодня сверхточные тахометры лазерного типа весьма популярны. Такие приборы позволяют проводить своевременные и точные измерения скоростей вращения поверхностей.

Тахометры выпускают трех различных видов. Первый тип – бесконтактные приборы. Здесь на вал тахометра прикрепляют специальную ленту, и прибор при вращении такого вала лазером или фотоэлементом производит подсчет числа возникновений метки. Вторым типом являются контактные тахометры, оснащенные специализированным контактным элементом, предназначение которого – отсчитывание скорости вращения. Третьего типа прибор относится к комбинированным и функционально совмещает в себе первый и второй тип.

Портативный тахометр DT-006 лазерного типа имеет интервал измерений 20～50000 оборотов в минуту. Измерения тахометр проводит с точностью 2×〖10〗^(-4)×N ± 1цифра. Время, за которое прибор будет адаптирован к условиям окружающей среды (рабочая температура 0ºC-50ºC) за 1сек.

Масса прибора – 300г. Расстояние для измерений: 50-400 мм, дисплей ЖК. Габариты – 78×38×180 мм.
