user's ,manual

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.

Multiparameter Instrument (carrying case (5061) and PC adaptor RS-232 included) used with the 556 handheld instrument.

Packed with Features：

Battery Options：
