Описание

Hanna Instruments с гордостью представляет  инновационный рН/ОВП метр edge®. Еdge 2002-02 объединил в себе последние достижения в области рН-метрии и современного дизайна. Это высокоточный прибор со множеством полезных функций в сверхтонком корпусе, толщина которого всего 13 мм. В комплект поставки входит комбинированный электрод, решающий широкий спектр задач, стоящих перед современной лабораторией . Edge является невероятно простым и удобным в использовании прибором, способным с высокой точностью измерять рН и ОВП.

Расширенные возможности диагностики рН электродов

Прибор edge обладает возможностью самодиагностики рН электродов, обеспечивающей точность измерений. В диагностику входит функция проверки калибровки CAL Check, предупреждающая пользователей о возможных проблемах во время калибровки, и функция проверки целостности стеклянного корпуса и соединений датчика.

Емкостной сенсор

Прибор edge имеет емкостную сенсорную клавиатуру, что придаёт ему современный и практичный внешний вид. Клавиатура имеет быстрый отклик и обладает достаточной чувствительностью при работе в лабораторных перчатках. Поскольку клавиатура является частью экрана, на ней нет кнопок, которые могут загрязниться остатками образца.

Большой легко читаемый ЖК экран

Прибор edge снабжён 5,5-дюймовым ЖК-дисплеем, на котором показания легко читаются с расстояния более 5 метров. Большой экран и широкий угол обзора (150°) обеспечиваются одним из удобных ЖК-дисплеев в отрасли.

Edge® рН/ОВП имеет большое количество функций, обеспечивающих точность измерений и удобство использования.

Цифровые рН электроды

Высокотехнологичные рН электроды для edge имеют встроенный микрочип, в котором хранится информация о калибровке. Информация из микрочипа загружается в память прибора при подключении  электрода. Поскольку информация о калибровке хранится в чипе рН электрода, а не в памяти прибора, то после замены электрода не требуется перекалибровывать прибор. Данная особенность позволяет существенно экономить время и растворы для калибровки при частой замене электродов.

Фунция CAL Check

Функция проверки калибровки CAL Check анализирует поведение рН электродов в буферных растворах рН во время процесса калибровки и предупреждает пользователя о возможных проблемах. Индикаторы высвечивают надпись «загрязненный буфер» и «очистите электрод». После калибровки индикаторы состояния электрода и времени отклика отображаются на экране. Состояние рН электрода оценивается по характеристикам смещения и наклона.

Проверка электрода

При работе с электродами Hanna, оснащенными 3,5 мм разъёмом, прибор edge непрерывно контролирует сопротивление измерительных рН электродов в реальном времени с целью немедленного уведомления в случае возникновения неполадок. Во время калибровки функция проверки датчика также проверяет состояние диафрагмы. Кроме того, состояние диафрагмы сравнения оценивается и отображается на дисплее.

Edge® универсальный прибор! Его можно использовать и как портативный, и как настольный прибор.

Настенное крепление

Используя каркас для настенного крепления (в комплекте), edge можно закрепить на стене, что позволяет освободить место на лабораторном столе. Каркас имеет встроенный разъем для питания edge и зарядки его аккумуляторов. Настенное крепление предназначено для экономии ценного настольного пространства.

Подставка и держатель электродов

Прибор edge комплектуется настольной подставкой со встроенным разъёмом питания edge, на которую крепится регулируемый поворотный штатив для электродов. Такая конструкция обеспечивает возможность зарядки и надёжной фиксации прибора при оптимальном угле обзора.

Edge® очень тонкий и весит всего 250 г. Время работы от батареи 8 часов. Прибор снабжён двумя разъёмами USB.

Два порта USB

Прибор edge оборудован одним стандартным USB разъёмом для экспорта данных на USB-накопитель и ещё одним микро USB разъёмом для подключения к компьютеру с целью экспорта файлов, а также для зарядки прибора при отсутствии подставки или настенного крепления.

Журнал данных

Прибор edge позволяет хранить до 1000 записей журнала данных. Каждая из них включает показания, данные стандарта GLP, дату и время.

Два режима работы

Прибор edge может использоваться в расширенном или базовом режимах эксплуатации. Расширенный режим предоставляет пользователю все имеющиеся возможности прибора, в то время как базовый режим сокращает количество функций до выполнения очень простых операций. Например, в расширенном режиме, edge предлагает калибровку по 5 точкам с использованием 2 пользовательских буферов, в то время как в основном режиме калибровка может быть выполнена только по 3 точкам и по 5 заранее запрограммированным значениям буферов.
