这是YSI WQS家族新一款先进的手持式水质多参数仪，它被设计用于点测量和剖面测量研究工作。产品采用YSI EXO新传感器技术，搭配Professional彩色显示器，可测量除叶绿素/蓝绿藻和fDOM以外的所有EXO测量参数,包括：光学溶解氧、浊度、pH、ORP、电导率、比电导率、总溶解固体、电阻、海水密度、总悬浮固体、深度、温度、硝酸盐、氨氮、氯。长达至100米的测量电缆可带或不带深度传感器，主机探头包含四个ProDSS传感器接口，主机可选GPS用于野外数据定位。
ProDSS传感器秉承YSI EXO传感器特性：具有钛质外壳，其智能传感器可被探头自动识别，多支相同传感器可被同时在同一主机上校准，然后分配给其他仪器和探头使用而不损失校准参数。长寿命的可充电锂离子电池确保野外可靠使用。ProDSS是一台真正意义上的野外仪器，它具有野外仪器要求的一切特性，如探头的快速更换、军方规格的快插接头、IP-67防水等级等等。
YSI长期致力于提供可靠的和性价比高的水质测量和监测仪器满足真实世界里的实际应用需要。
