Featuring a waterproof IP-67, impact-resistant case, the YSI 556 MPS simultaneously measures dissolved oxygen, pH, conductivity, temperature, and ORP. Or, simply purchase the cable to measure DO, conductivity, and temperature if needed. The YSI 556 MPS conforms to GLP standards.
Designed for use in applications such as surface water, groundwater, coastal/estuarine, aquaculture, and wastewater, the rugged and reliable 556 allows for the measurement of water quality parameters with digital sensors. The YSI 556 water quality meter uses smart sensor technology that allows sensors to be automatically recognized by the handheld while retaining calibration data.
