YSI 556 Multi-Probe System, Hp: 081380328072, Email : k00011100@ yahoo.com

The YSI 556 simultaneously measures dissolved oxygen, pH, conductivity, temperature, and ORP. Rugged, reliable and waterproof, the YSI 556 MPS ( Multi-Probe System) combines the versatility of an easy-to-use, easy-to-read handheld unit with all the functionality of a multi-parameter system. Featuring an IP-67, impact-resistant case, the YSI 556 MPS assists the user in conforming to GLP standards. Measurements are easy with field-replaceable DO electrode modules and easy-to-use, screw-on cap DO membranes. Two models are available. The standard model measures dissolved oxygen, pH, conductivity, temperature and ORP. The YSI 556 model with an internal barometer provides barometric pressure measurements in addition to the measurements taken by the standard model. Features: * Field-replaceable DO electrode modules * RS232 and compatible with Ecowatch™ for Windows™ data analysis software * Easy-to-use, screw-on cap DO membranes * 3-year warranty on the instrument, 1-year on the probe module and cables * Stores over 49, 000 data sets, time and date stamped * User upgradeable software from YSI * Meets IP-68 water tightness requirements, submersible to 3 feet Order the instrument, cable and accessories separately.
