pH-метр HANNA Instruments HI9829-01042

Датчик передает показания в цифровом виде с возможностью регистрации данных при отключении от контроллера. Дополнительный GPS обеспечивает отслеживание местоположения измерений. Вся система проста в настройке и удобна в использовании. Модель HI9829 легко настраивается и поставляется со всеми необходимыми аксессуарами, упакованными в прочный чехол для переноски.

pH-метры для бассейнов, будучи частным случаем приборов для анализа жидкостей, обладают уникальными особенностями, несмотря на свою внешнюю схожесть с универсальными моделями, которые также применяются в водоочистке и пищевой промышленности. Ключевая особенность их эксплуатации - необходимость более тщательного ухода и регулярной калибровки. Причина этого кроется в агрессивной хлорированной среде, жёсткий химический состав которой активнее воздействует на электрод, постепенно снижая точность его измерений. С конструктивной точки зрения, рынок предлагает два формата устройств: Портативные (предназначены для быстрого экспресс-тестирования), Стационарные (обеспечивают непрерывный мониторинг и часто интегрируют дополнительные функции, такие как замер температуры, солёности или ОВП).
