温度
索林斯特尤里卡仪器使用热敏电阻测量温度，热敏电阻是一种小型半导体，其电阻随温度变化而变化。
pH 值
pH 值通过 pH 传感器和参比电极进行测量。pH 传感器是一个小玻璃球，里面装有已知 pH 值的电解质。
浊度
浊度表示通过水柱的光量。清澈的水浑浊度低；悬浮固体含量高的水浑浊度高。

ISE 离子选择电极
Solinst Eureka 的流动结参比电极比胶状电解质参比电极具有更好的长期稳定性。只需拧下电极头，在传感器中注入新鲜电解液，然后将电极头拧回原位，参比电极就能轻松恢复活力。
PAR（光合有效辐射）
大多数 PAR（光合有效辐射）传感器在与多参数水质探测仪结合使用时，都需要额外的安装支架或笼子来固定 PAR 传感器。Solinst Eureka 的 PAR 传感器不需要这样做，因为它们与探头本体相连。为方便起见，索林斯特-尤里卡公司的 PAR 传感器在不使用时可以取下并用防水插头替换。
