Overview — VIKING-M510T-A portable multi-parameter meter
VIKING-M510 from COLO.Science is a rugged IP65 portable instrument for pH, mV/ORP, conductivity, resistivity, TDS, salinity, ISE, dissolved oxygen and temperature. It features a bright 4.3″ color touchscreen, an intelligent OS with user/calibration/electrode/method/data management, and GLP-compliant memory (1000 groups per parameter) for traceable results. Multi-reading modes (Auto-Read, Timed-Read, Continuous) and automatic/manual temperature compensation ensure reliable measurements in the lab or in the field.
