DISCONTINUED SEE YSI Propessional Plus Rugged and reliable, the YSI 556 MPS (Multiprobe System) combines the versatility of an easy-to-use, easy-to-read handheld unit with all the functionality of a multiparameter system.

The YSI 556 MPS can simultaneously measure dissolved oxygen, pH, conductivity, temperature and ORP. The instrument features field-replaceable electrodes and is compatible with EcoWatch® for Windows® data analysis software. The YSI 556 MPS stores over 49,000 data sets, has a time and date stamp with interval or manual logging.

The YSI 556 MPS conforms to GLP standards and records calibration data in the memory. The 556 MPS comes with an IP67, impact-resistant, waterproof case and an RS-232 interface to connect to a PC.
