Rugged and reliable, the YSI 556 MPS (Multi-Probe System) combines the versatility of an easy-to-use, easy-to-read handheld meter with all the functionality of a multi-parameter system. Housed in a waterproof IP-67, impact-resistant case, the YSI 556 MPS simultaneously measures dissolved oxygen (D/O), conductivity, temperature, pH, and ORP.
Features include; Field-replaceable sensor modules; Easy-to-use screw-on cap D/O membranes; Automatic push-button calibration & temperature compensation (ATC); Battery indicator; Memory for over 49,000 data sets time and date stamped; RS232 data output compatible with Ecowatch for Windows data analysis software; and Three-year warranty on the instrument and one-year on the probe modules.
An optional internal barometer can be user-calibrated and displayed along with other data, used in dissolved oxygen calibrations, and logged to memory for tracking changes in barometric pressure. Available with 4,10, and 20 m cable lengths, each unit is supplied with a replacement D/O membrane kit, 4 C cell alkaline batteries, soft-sided carrying case with enough space for the YSI 556 MPS, 4-meter cable and calibration supplies.
