压力

绝对深度传感器（压力传感器）或通风深度传感器可与其他传感器一起添加到任何 Manta 或 Trimeter 多探头上。

溶解气体总量

Solinst Eureka 的 TDG 传感器与水质监测行业的其他产品类似。不过，索林斯特尤里卡公司是少数几家提供 TDG 传感器的多探头制造商之一，这种传感器还可与溶解氧、浊度、pH 值和电导率等其他传感器一起安装在多探头上。

二氧化碳

Solinst Eureka 的 CO₂（二氧化碳）传感器是同类便携式水质仪器中的佼佼者。虽然它是一个大型传感器，但可以与溶解氧、pH 值和电导率等其他传感器一起安装在 MantaPlus 40 多探头中。

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

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。

荧光素

Solinst Eureka 使用荧光素传感器。荧光素传感器可与其他传感器（如附加荧光计、浊度、溶解氧、pH 值和电导率）一起安装在探头中。由于无需购买专用的荧光计，因此这种方法具有很高的成本效益。
